Description

Display device and related glasses

technical field

The invention relates to a display device capable of processing three-dimensional content, and the display device and glasses. In particular, it relates to a three-dimensional (3D) content playback system based on active shutter or passive polarized glasses and a display device, which enhances the degree of cooperation between the glasses and the display device, so as to provide an additional value-added application display device.

Background technique

In the modern information society, a large amount of information, information, news, knowledge, opinions, ideas, experience and interactive content has been electronically transformed into digital content; these contents can be played to users by audio-visual playback systems. In order to further enhance the user's audio-visual experience, playing 3D content has become one of the important development trends of the playing system in the future.

Contents of the invention

3D content playback can be realized by active shutter glasses or passive polarized light with a display device. For example, the transparency of the left and right lenses of the active shutter glasses can be controlled separately to penetrate or block the image displayed by the display device. When the display device displays a left image, the left lens of the glasses penetrates synchronously, and the right lens blocks synchronously, so as to present the left image to the left eye of the user. When the display device displays a right image, the left lens is blocked synchronously and the right lens is penetrated synchronously, so that the right image can be conveyed to the user's right eye. By transmitting the left and right images to the left and right eyes of the user respectively, the parallax between the left and right images can be used to allow the user to experience the 3D image synthesized by the left and right images, achieving the 3D display Purpose.

In order to synchronize the penetrating/shielding operation of the glasses with the picture displayed by the display device, the display device will broadcast a remote synchronization signal to the glasses, so that the glasses can set the timing of switching transparency of the lenses accordingly. However, this simple one-way broadcast communication (from the display device to the glasses) also limits the overall application of the playback system; for example, the display device cannot confirm the operating status of the glasses, nor can it reflect the operating status of the glasses to the user. When the operating state of the glasses changes, the display device cannot respond. If there are multiple users wearing their own glasses in the playback system, the display device cannot identify the glasses and cannot provide individual services for the glasses.

Shutter glasses require a power supply to drive the left and right lenses to switch between transmission and blocking. Considering the convenience and comfort of wearing, the shutter glasses are powered by batteries. However, due to the limited power of the battery, the glasses should try their best to save unnecessary power consumption to increase their operating time. Although the shutter glasses can be equipped with a power switch to allow the user to turn off the power when the glasses are not in use, this will increase the user's control burden; if the user forgets to turn off the power when the glasses are not in use, it will still cause unnecessary energy consumption. In addition, it is also difficult for the user to know the remaining power of the battery.

Although the 3D display can enhance the user's audio-visual experience, it is also easy to make the user feel tired. Therefore, it is necessary for the display device to provide a function of correctly extracting 2D content from 3D content and displaying it in 2D, so that users can still watch 3D content in 2D. In addition, if the display device only has 2D display capability, the aforementioned 2D content capture function can also make the display device compatible with 3D content.

In order to solve the above problems, one object of the present invention is to provide a kind of active shutter glasses for viewing three-dimensional image content, which includes a pair of lenses, a lens driver, a controller, a power supply circuit, a receiving circuit and a transmitting circuit . The lens driver is used to drive the lens to change the state of transparency; the lens driver changes the transparency of the pair of lenses with a frequency, wherein the frequency corresponds to the output of the 3D image content. The controller is used to control the operation of the lens driver and provide a status signal. The power circuit provides power for the lens driver and the glasses. The receiving circuit receives the remote control signal sent by the display device. The transmitting circuit generates a corresponding transmitting signal according to the status signal and transmits the transmitting signal to the display device to establish two-way communication with the display device. For example, the controller at the glasses side can reflect the power supply status of the power circuit in the status signal, and the display device can display the power supply status of the glasses to the user in the form of pictures and/or sounds, so that the user can respond early. For another example, when the user turns off the power of the glasses and/or the power supply circuit terminates the power supply to the lens driver, the glasses can also return their status before the power is turned off, so that the display device can jointly stop or pause the playback of the three-dimensional content, switch to a two-dimensional display without glasses; or, the display device can also be powered off accordingly, or enter a relatively power-saving standby state.

Similarly, the operating status of the lens driver can also be reflected in the status signal and sent back to the display device. For example, the lens driver of the present invention can simultaneously make the left and right lenses penetrate under the control of the user; the display device can also automatically switch to two-dimensional display through the response of the state signal.

The remote control signal sent by the display device is not limited to a synchronous signal, and can also include various instructions and information; and the glasses can also use status signals to respond to the remote control signal. A memory circuit can be provided at the glasses end to record operation information for the controller, and the operation information can also be reflected in a status signal to be sent back to the display device. For example, each glasses can have an identification code built in the memory circuit; the display device can send an identification command in the remote control signal, so that each glasses can return the identification code to the display device. In this way, the display device can identify each pair of glasses, and provide individual services and applications for each pair of glasses. For example, the display device can send polls to different glasses for different identification codes in the remote control signal, and each glasses judges whether the identification code in the remote control command matches its own built-in identification code, and if so, the glasses can return its own operational status. In this way, each glasses can respectively send back its operation status (such as power supply status) to the display device, and the display device can monitor and/or respond to the operation status of individual glasses respectively.

A proximity sensor can also be provided in the glasses of the present invention to sense whether the glasses approach and/or touch the user and provide a corresponding proximity signal, thereby judging whether the glasses have been worn by the user. The proximity signal can also be reflected in the status signal by the controller, so that both the display device and the glasses can operate according to the status signal. For example, when the user wears the glasses, the glasses can be automatically woken up from the power-saving standby state, and the display device can be automatically powered on and/or start 3D display through the status signal. Similarly, when the user no longer wears the glasses, the glasses can automatically enter the standby state and/or turn off the power; before turning off the power, the display device can be notified through a status signal, so that the display device stops 3D display and switches to 2D display , enter standby and/or turn off the power.

The transmitting circuit function in the glasses of the present invention can be realized by the light signal of the glasses itself. The glasses can use the visible light of the light signal to indicate to the user its operating status (for example, whether the power is turned on), and the present invention can use the existing light signal of the glasses to send an encoded/modulated status signal to the display device, such as It responds to the state signal with the frequency (period) of light and dark changes in timing; the frequency of light and dark changes can be greater than the frequency that can be detected by the human eye, without affecting the original indication function of the light. And the display device side can be provided with an image capture device to capture the status signal in the light signal. In addition, the transmitting circuit of the glasses can be a transmitting circuit that emits electromagnetic waves in the infrared frequency band, which can carry the state signal of the glasses end with the infrared signal; the display device can use the existing infrared remote control receiving circuit to receive the state signal of the glasses end. The transmitting circuit of the glasses and the corresponding receiving circuit of the display device may also be an electromagnetic wave transmitting circuit and receiving circuit of a radio frequency radio or a Bluetooth radio.

Another object of the present invention is to provide a pair of glasses for 3D display, which is provided with a pair of lenses, a lens driver, a proximity sensor and a power circuit. The proximity sensor senses whether the glasses are worn and generates a corresponding proximity signal. The lens driver can decide whether to drive each lens according to the proximity signal; when the glasses are worn, the lens driver can automatically start driving each lens, and when the glasses are not worn, the lens driver can automatically stop driving the lenses to save power consumption. Alternatively, the power supply circuit can also determine whether to provide power to the lens driver according to the proximity signal. The glasses can also be provided with a transmitting circuit to generate a corresponding transmitting signal and transmit the transmitting signal according to the proximity signal and the state signal of the glasses controller.

Another object of the present invention is to provide a display device, which includes a display, a control circuit and a receiving circuit. The display device can be matched with the glasses of the present invention to form a playback system with three-dimensional display capability. Wherein, the display can operate in a 3D mode and a 2D mode to display 3D image content and 2D image content respectively. The control circuit controls the operation mode of the display and the operation of the display device/playing system. The receiving circuit receives a state signal, and the control circuit can switch the operation mode of the display according to the state signal, for example, switch from the 3D mode of 3D display to the 2D mode of 2D display. The status signal can be sent by the remote controller of the display device itself, or can be sent by the glasses.

According to the status signal actively sent by the glasses end, many value-added applications can be provided for the playback system, as discussed above. For example, the control circuit of the display device can provide a status content according to the status signal, and the status content is played by the display, so that the user of the glasses can know the operating status of the glasses through the display of the display device, such as the remaining power of the glasses, etc. . The display of the display device can switch between the two-dimensional mode and the three-dimensional mode according to the state signal, and the power supply circuit of the display device can also control the power supply state of the display device according to the state signal.

An image processing module can be set in the display device of the present invention to extract two-dimensional content from three-dimensional content. The 3D content carries at least one set of left frames and right frames, and each set of left frames and right frames forms a 3D image. A format conversion module and a scaling module can be set in the image processing module. The format conversion module can extract each group of left and right images from the three-dimensional content, and select one of them from each group of left and right images; the scaling module can scale the selected images according to the resolution of the display. .

Yet another object of the present invention is to provide a display device with glasses, which includes a display, an image capture device, an identification module and a control circuit. The image capture device is used to capture images; the identification module identifies whether the glasses are worn from the images, and provides a corresponding identification result. The control circuit controls the display according to the identification result. A transmitter circuit can also be set at the display device end, which can send a remote control signal to the glasses according to the identification result. For example, when the identification module recognizes that glasses are worn, the display can automatically start 3D display, and send a remote control signal to the glasses, so that the glasses can automatically wake up from the standby state and/or start to cooperate with 3D display. When the identification module does not recognize that the glasses are worn, the display can automatically terminate/pause the 3D mode, switch to the 2D mode, enter the standby state and/or turn off its own power, and can also send a remote control signal to the glasses before the power is turned off, so that The glasses correspondingly stop driving the left and right lenses alternately, make the left and right lenses penetrate, enter the standby state and/or turn off the power supply.

Another object of the present invention is to provide a display device, which includes a display and an image processing module. The display is used to display 2D image content; the image processing module extracts 2D image content from a 3D image content for display on the display. The 3D image content carries at least one set of left and right frames, and each left and right frame forms a 3D image; and the image processing module includes a format judging module, a format converting module and a zooming module. The format judgment module judges the format of the 3D image content, and the format conversion module extracts at least one set of left and right frames from the 3D image content according to the format, and selects one of them from each set of left and right frames to serve as Frames of 2D video content. The scaling module scales the left frame (or the right frame) selected by the display resolution scaling format conversion module.

Another object of the present invention is to provide a display device matched with a pair of glasses, which includes a display, a control circuit and a transmitting circuit. The display can operate in a 3D mode and a 2D mode; the display operates in 3D mode to display 3D image content, and operates in 2D mode to display 2D image content. The control circuit controls the display to operate in either a three-dimensional mode or a two-dimensional mode. The transmitting circuit sends a wireless signal to the glasses according to an audio signal related to an image content.

Another object of the present invention is to provide a pair of glasses for viewing a 3D image output, which includes a pair of lenses, a receiving circuit and an audio playback unit. The receiving circuit is used to receive a wireless signal, and the wireless signal is an audio signal related to the 3D image. The sound effect playing unit generates a sound effect according to the audio signal.

Detailed ways

Please refer to FIG. 1 , which shows a schematic diagram of an embodiment 10a of glasses of the present invention. The glasses 10a may be active shutter glasses for 3D display, and are combined with a display device 30a to form a playback system 100 capable of playing 3D content. The glasses 10a are provided with two lenses GR and GL, a lens driver 12a, a controller 20a, a receiving circuit RxGa and a power supply circuit 14a. In order to realize the present invention, a proximity sensor 22 is also provided in the glasses 10a.

In the glasses 10a, the lenses GR and GL are left and right lenses, respectively. The lens driver 12a is used to drive the lenses GR and GL to change the transparency so that the lenses GR and GL can respectively penetrate or block the picture displayed by the display device 30a. The receiving circuit RxGa receives the remote control signal sent by the display device 30a. The controller 20a mainly controls the overall operation of the glasses 12a, and can control the operation of the lens driver 12a according to the remote control signal received by the receiving circuit RxGa. The power circuit 14a provides power for the lens driver 12a and even the glasses 10a.

The situation of three-dimensional display by the playback system 100 can be described as follows. The display device 30a will send a remote control signal to the glasses 10a, so that the glasses 10a can be synchronized with the display device 30a. When the display device 30a displays a left image, the left lens GL of the glasses 10a transmits it synchronously, and the right lens GR blocks it synchronously, so as to present the left image to the left eye of the user. When the display device 30a displays a right image, the left lens GL is blocked synchronously and the right lens GR is transmitted synchronously, so that the right image can be conveyed to the user's right eye. By transmitting the left image and the right image to the left eye and the right eye of the user respectively, the parallax between the left image and the right image can be used to allow the user to feel the 3D image synthesized by the left image and the right image.

A speaker 16 (such as a monophonic or multi-channel earphone) and/or a vibrator 18 can also be optionally provided on the glasses 10a. The three-dimensional content (three-dimensional image content) played by the display device 30a may include sound data (audio signal) and/or vibration data; when the display device 30a plays the three-dimensional content, the sound data and/or vibration data may be carried in the The remote control signal is transmitted to the glasses 10a and received by the receiving circuit RxGa of the glasses 10a. The speaker 16 can convert the sound data into sound waves, and the vibrator 18 converts the vibration data into vibrations that the user can actually feel, so as to enhance the user's sense of presence when watching three-dimensional content.

In the glasses 10a according to an embodiment of the present invention, the proximity sensor 22 is used to sense whether the glasses 10a are worn, and generate a corresponding proximity signal SC. The controller 20a can control the lens driver 12a according to the proximity signal SC to determine whether to drive the lenses GR and GL. That is to say, when the proximity signal SC reflects that the glasses 10a are worn, the lens driver 12a drives the lenses GR and GL for three-dimensional display; when the glasses 10a are not worn, the lens driver 12a stops driving the lenses GR and GL, to save power consumption.

Alternatively, the controller 20a can also control the operation of the power supply circuit 14a according to the proximity signal SC to determine whether to provide power to the lens driver 12a and/or the entire glasses 10a. For example, when the proximity sensor 22 senses that the glasses 10a are worn by the user, it means that the user is ready to watch 3D content, and the power circuit 14a can supply power to the lens driver 12a to start driving the lenses GR and GL. Relatively, when the proximity sensor 22 senses that the glasses 10a are not worn (such as when the user takes off the glasses 10a), the controller 20a and the power supply circuit 14a can enter into a power-saving standby state; for example , the power supply circuit 14a can stop supplying power to the lens driver 12a and the receiving circuit RxGa (even the speaker 16 and/or the vibrator 18), and only supply power to the proximity sensor 22, so that the proximity sensor 22 can periodically sense the glasses 10a is worn by the user. When the proximity sensor 22 senses that the glasses 10a are worn again, the controller 20a can be woken up from the standby state, and the power supply circuit 14a will also fully supply power to the receiving circuit RxGa and the lens driver 12a (and the speaker 16 and/or or vibrator 18). In addition, when the glasses 10a are not worn, the power circuit 14c can be turned off, and even the proximity sensor 22 stops working. The user can turn on the power of the glasses 10a again through a power switch (not shown in FIG. 1 ) of the glasses 10a.

In other words, the glasses 10 a according to the embodiment of the present invention can be automatically activated/deactivated according to whether the glasses are worn, without the need for the user to manually activate/deactivate the active shutter glasses. The glasses 10a of the present invention can also more effectively save unnecessary power consumption and prolong the service life of the active shutter glasses.

When implementing the glasses 10a of the present invention, the proximity sensor 22 can be a push-type mechanical switch, which is set on the glasses 10a at a position where it will be in contact with the user, such as the position P1 close to the bridge of the nose, and/or on the temples The position P2, as shown in Figure 1. When the user wears the glasses 10a, the push-type mechanical switch at the above position is pressed due to contact with the human body, so that the proximity sensor 22 can detect that the glasses 10a have been worn. Conversely, when the user no longer wears the glasses 10a, the push-type mechanical switch is released, and the proximity sensor 22 can detect that the glasses 10a are not worn. In addition, the proximity sensor 22 can also be made of piezoelectric material, which can respectively send out different electrical signals as the proximity signal SC under the condition of force and no force. Furthermore, the proximity sensor 22 can also be an infrared or ultrasonic rangefinder, and when it senses an object approaching, it can be determined that the glasses 10a have been worn. For another example, the proximity sensor 22 can also be formed by a transmitter and a receiver (such as a low-power infrared transmitter and a photosensitive circuit), the transmitter is arranged at one end of the glasses, and the receiver is arranged at the other end, forming a path between the two signal, when the signal between the two is blocked, it means that the glasses 10a have been worn.

Please refer to FIG. 2 , which shows another embodiment 200 of a playback system according to an embodiment of the present invention. The playback system 200 uses the display device 30b together with the glasses 10b to perform 3D display. The display device 30b includes a display 32, a control circuit 40b, a power circuit 46b, a transmitting circuit TxDb, a video circuit 34b, a video processing module 36b, a frame buffer 38 and a driving circuit 42b. The video circuit 34b receives video and audio content, and performs appropriate demodulation/decoding to extract data to be played from the content, such as picture data, sound data and/or vibration data. Utilizing the memory space provided by the frame buffer 38, the image processing module 36b extracts each frame (frame) from the frame data, and arranges the timing of playing each frame. The driving circuit 42b drives the display 32 to display the image provided by the image processing module 36b. The control circuit 40b mainly controls the operation of the display device 30b, and the power circuit 46b controls the power supply in the display device 30b.

Similar to the glasses 10a in FIG. 1, the glasses 10b in FIG. vibrator18. The control circuit 40b in the display device 30b can send a remote control signal Sm to the glasses 10b via the transmitting circuit TxDb; for example, the remote control signal Sm can include a synchronization signal for three-dimensional display. The controller 20b of the glasses 10b can coordinate the operation timing of the lens driver 12b to cooperate with the display device 30b to realize three-dimensional display. In addition, in addition to transmitting the remote control signal, the transmission circuit can also transmit another wireless signal (or included in the remote control signal) to the glasses according to the audio signal in an image content to further generate sound effects, such as music or vibration. Please note that the display device in this embodiment may not have the ability to receive wireless signals. The glasses can also only have a receiving circuit and an audio playback unit. When the user wears the 3D glasses to watch the 3D content, the 3D glasses can receive the audio signal related to the 3D content, and convert it into a sound effect, such as music or vibration, and play it through the sound effect playing unit. For example, the 3D glasses may include earphones with wireless receiving circuits, such as bluetooth earphones, and the bluetooth earphones can receive audio signals sent from the display device and generate sound effects accordingly.

In order to improve the function of the display device 30b, the image processing module 36b of an embodiment of the present invention can extract the 2D content from the 3D content, and display the image of the 2D content on the display 32 . In other words, the display 32 can operate in a 3D mode and a 2D mode, displaying content in 3D format and content in 2D format respectively, wherein the content in 2D format can be extracted from the content in 3D format , to display content in 3D format in 2D. As mentioned above, watching the 3D content displayed in 3D for a long time is more likely to make the user feel tired and even feel uncomfortable; A comfortable way to watch 3D content. When the 3D content is interleaved with the left and right images displayed on the display, the user who directly watches the image with the naked eye without shutter glasses will feel that the image is shaken and blurred due to the parallax between the left and right images.

In order to correctly display the 3D content in a 2D format, as shown in FIG. 2 , the image processing module 36 b of the present invention is provided with a format judgment module 52 , a format conversion module 54 and a scaling module 56 . The format judging module 52 judges which format carries the left frame and the right frame of the 3D image in the 3D content, and the format conversion module 54 extracts the left frame and the right frame from the 3D content according to the protocol of each format (which can be temporarily stored in frame buffer 38), and select one of them to form a two-dimensional content frame. For example, the format converting module 54 can fixedly select the left frame in each 3D image to form 2D content and play it. In this way, the user can comfortably watch 3D content displayed in 2D. In addition, the images obtained by the format converting module 54 may not necessarily conform to the resolution of the display 32 , and the scaling module 56 is used to properly scale each image horizontally and/or vertically so that each image can conform to the resolution of the display 32 . The operation of the image processing module 36b of the present invention will be further described later. In another embodiment, the image circuit, the control circuit and the drive circuit may also be included in the image processing module.

In addition to the function of displaying 3D content in 2D, an image capture device 58 and a recognition module 62 may be added to the display device 30b of the present invention to provide further value-added applications for the playback system 200 of the present invention. Among them, the image capture device 58 is used to capture the image; the identification module 62 identifies whether the glasses 10b are worn from the image, and provides a corresponding identification result RI; and the control circuit 40b can control the display 32 according to the identification result RI (and display device 30b). For example, when the recognition module 62 recognizes that the glasses 10b are worn, the control circuit 40b can automatically enable the display 32 to start three-dimensional display. When the identification module 62 does not recognize that the glasses 10b are worn, the control circuit 40b can automatically enable the image processing module 36b to start capturing 2D content from the 3D content, and the display 32 can also terminate the 3D mode and automatically switch to the 2D mode to display 3D content in 2D.

Or, when the identification module 62 does not recognize that the glasses 10b are worn, the control circuit 40b can also automatically cause the display device 30b to suspend playback and enter a power-saving standby state; the power supply circuit 46b can suspend supplying power to the drive circuit 42b and the display 32 to save unnecessary power consumption. The power supply to the image circuit 34b, the image processing module 36b, and the frame buffer 38 can also be suspended (or only part of the power is reserved to temporarily store the playback progress); the power supply of the transmitting circuit TxDc can be terminated, and some functions of the control circuit 40b can also be suspended Can be turned off to further reduce power consumption. However, the power circuit 46b can supply power to the image capture device 58 and the identification module 62, so that the image capture device 58/identification module 62 can periodically identify whether the glasses 10b are worn again. When the glasses 10b are worn again, the identification module 62 can use the identification result RI to wake up the control circuit 40b, and enable the power supply circuit 46b to automatically restore full power supply to the display device 30b.

In another embodiment, when the recognition module 62 does not recognize that the glasses 10b are worn, the display device 30b can further turn off the display device 30b, and even the image capture device 58 and the recognition module 62 are completely stopped; the user A power switch (not shown) of the display device 30b can be used to turn on the power of the display device 30b again. Or, when the identification module 62 does not recognize that the glasses 10b are worn, the control circuit 40b can ask the user via the display 32 with an image or voice whether to switch to the two-dimensional mode or whether to make the display device 30b enter a power-saving standby mode. state, and/or whether to turn off the power of the display device 30b. For another example, when the identification module 62 does not recognize that the glasses 10b are worn, the control circuit 40b can decide whether to switch to the 2D mode or enter the standby state according to the characteristics of the 3D content; for example, if the 3D content is a 3D live broadcast, The control circuit 40b switches to two-dimensional display when the glasses 10b are not worn. If the 3D content is not rebroadcasted in real time, the control circuit 40b can enter a standby state.

In other words, through the operation of the image capture device 58 and the identification module 62, the user can trigger the automatic switching operation of the display device 30b of the present invention by putting on and taking off the shutter glasses. In another specific embodiment, the control circuit 40b of the display device 30b can also control the glasses 10b according to the recognition result RI. For example, when the recognition module 62 does not recognize that the glasses 10b are worn, the control circuit 40b of the display device 30b may carry a standby instruction in the remote control signal Sm, and send it to the glasses 10b through the transmitting circuit RxGb. After the glasses 10b receive the remote control signal, the controller 20b of the glasses 10b can enable the power supply circuit 14b to perform energy-saving operations, such as stopping power supply to the lens driver 12b (and the speaker 16/vibrator 18), and the controller 20b can also turn off some function to reduce unnecessary power consumption, but the receiving circuit RxGb can obtain proper power supply to continuously receive subsequent remote control signals. When the display device 30b recognizes that the glasses 10b have been put on again, the display device 30b can wake up the glasses 10b with a remote control signal, so that the glasses 10b can resume full operation.

When using the image capture device 58 and the recognition module 62 to actually realize the image recognition of wearing glasses, various embodiments can be implemented as follows. Image recognition can search for faces in the captured images. After searching for a face, since there will be a difference in color and/or brightness between the frame/lens of the shutter glasses and the face, it can be used to determine whether the user is The shutter glasses 10b have been worn. The front of the glasses 10b facing the display 32 can also be provided with a specific form of barcode (such as the barcode 68 in FIG. 2 ), texture, pattern, and color for identification. Alternatively, the front of the glasses 10b has a specific shape, and the recognition module 62 can compare whether the front shape of the glasses 10b appears in the captured image, and judge whether the user has worn the glasses 10b accordingly.

In addition, since the lenses GR and GL of the glasses 10b switch between shielding and transmission under the control of the display device 30b, this feature can also be used to identify whether the user is wearing the glasses 10b. For example, when the display 32 is displaying the left picture and the right picture and controlling the lenses GR and GL, the image capture module 58 can also capture images synchronously and compare the differences between the images; The image recognizes that the user's right eye is blocked but can see the left eye, and the image captured while the right frame is displayed recognizes that the user's left eye is blocked but can see the right eye, and/or when both lenses are GR When both GL and GL are under controlled occlusion, it is captured and recognized that both eyes of the user are occluded, which means that the user has worn shutter glasses. Alternatively, the image capture module 58 can also capture images at a higher frequency (higher than the frequency at which the display updates the screen), and analyze the frequency of light and dark changes of the face according to a series of images captured. /or the frequency of light and dark changes of the same part of the face matches the frame update frequency, and it can also be judged that the user has worn the shutter glasses 10b based on this.

In one embodiment of the present invention, the user can manually control the glasses 10b so that both the lenses GR and GL continue to pass through (that is, turn off the 3D function of the 3D glasses) to view 2D displayed images. When the recognition module 62 recognizes that the user has worn the glasses 10b and both lenses GR and GL are transparent, the display 32 of the display device 30b can automatically switch to the 2D mode, for example, to display 3D content in 2D.

In yet another embodiment of the present invention, the image capture device 58/identification module 62 can identify whether the glasses 10b are worn according to the light signal on the glasses 10b. The glasses 10b can use the visible light of the lights (such as the lights 66 ) to indicate the operating status to the user, for example, whether the glasses are powered on. As shown in Figure 2, the controller 20b can reflect the operating status of the glasses 10b to a light signal control signal SL, and the transmitting circuit TxGb provided on the glasses 10b sends out a light signal visible to the user according to the light signal control signal SL. ; And the display device 200 of this embodiment can use this light signal to determine whether the user wears the glasses 10b. For example, when the recognition module 62 recognizes that the user is wearing glasses from the captured image, and the light spots on the glasses match the characteristics of the light signal, it can be determined that the user is wearing the glasses 10b.

By utilizing the existing indicator lights of the glasses 10b, the present invention can further expand the functions and applications of the display device 200. For example, the glasses 10b can send coded/modulated signals to the display device 30b by using the light signal sent by the transmitter TxGb, and further establish a two-way communication channel with the display device 30b. As shown in FIG. 2, a modulation circuit 64 can be set in the glasses 10b of this embodiment to modulate the state signal STb provided by the controller 20b; for example, the modulation circuit 64 can make The transmitting circuit TxGb can reflect the content of the state signal STb with the frequency (period) of light and dark changes in timing. The frequency of this light and dark change can be greater than the frequency that can be detected by human eyes, without affecting the original indication function of the indicator light. When the image capture device 58 of the display device 30b captures the image of the light signal, the identification module 62 can demodulate it, so that the control circuit 40b of the display device 30b can receive the status signal STb fed back by the glasses 10b.

After the two-way communication channel is established between the glasses 10b and the display device 30b, more value-added applications can be provided. For example, the controller 20b of the glasses 10b can reflect the power supply status of its power supply circuit 14b in the status signal STb, and the display device 30b can display the power supply status of the glasses (such as remaining power, estimated operating time, power supply will End-of-life warnings, etc.) are played to the user in the form of pictures and/or sounds, so that the user can respond as soon as possible. In addition, as mentioned above, the lens driver 12b of the present invention can simultaneously make the left and right lenses GR and GL penetrate under the control of the user; at this time, the glasses 10b can also notify the display device 30b through the state signal STb, so The display device 30b can automatically switch to two-dimensional display.

The remote control signal Sm sent from the display device 30b to the glasses 10b may include not only synchronous signals necessary for three-dimensional display, but also various instructions and information; and the glasses 10b may also use the transmitting circuit TxGb to send a status signal STb in response to the display. The remote control signal Sm of the device 30b. For example, the glasses 10b have a memory circuit 24 for recording operation information for the controller 20b. These operating information can be reflected in the state signal STb to be sent back to the display device 30b.

Please refer to FIG. 3 , which shows another embodiment 300 of the playback system of the present invention. In the playback system 300, the glasses 10c are matched with the display device 30c. The display device 30b is provided with a display 32, a control circuit 40c, a power supply circuit 46c, a transmitting circuit TxDc, a receiving circuit RxD, an image circuit 34c, an image processing module 36c, a frame buffer 38 and a drive circuit 42c. The operation of image circuit 34c, image processing module 36c, frame buffer 38 and driving circuit 42c is similar to image circuit 34b, image processing module 36b, frame buffer 38 and driving circuit 42b among Fig. 2; Image processing module 36c is the same The 2D content can be extracted from the 3D content, so that the screen of the display 32 can display the 3D content in 2D. The control circuit 40c mainly controls the operation of the display device 30c, and the power circuit 46c controls the power supply in the display device 30c.

Similar to the glasses 10b in FIG. 2 , the glasses 10c in FIG. 3 are equipped with a controller 20c, a lens driver 12c, lenses GR/GL, a receiving circuit RxGc, and a memory circuit 24, and can optionally be equipped with an earphone 16 and a vibrator 18. The control circuit 40c in the display device 30c can send a remote control signal Sm to the glasses 10c via the transmitting circuit TxDc; for example, the remote control signal Sm can include a synchronization signal for three-dimensional display, when the receiving circuit RxGc of the glasses 10c receives the remote control signal Sm, The controller 20c can coordinate the operation timing of the lens driver 12c to cooperate with the display device 30c to realize three-dimensional display.

In order to realize the present invention, a transmitting circuit TxGc can be additionally added in the glasses 10c according to an embodiment of the present invention, to encode/modulate the state signal STc provided by the controller 20c into an electromagnetic wave transmitting signal and transmit it; correspondingly, the display device The receiving circuit RxD in 30c can receive the state signal STc in the transmitted signal, and demodulate/decode it into an electronic state signal STc, so that the control circuit 40c of the playback circuit 30c can receive the state signal STc returned by the glasses 10c. By combining the transmitting circuit TxGc/receiving circuit RxD and the transmitting circuit TxDc/receiving circuit RxGc, a two-way communication channel can be established between the glasses 10c and the display device 30c. The receiving circuit RxD of the display device 30c may be an existing remote control receiving circuit of the display device 30c itself. Alternatively, the receiving circuit RxD can also be additionally added without using the remote control receiving circuit of the remote controller. The transmitting circuit TxGc and the receiving circuit RxD can use infrared rays, radio frequency radios, bluetooth radios or even physical wires to transmit the status signal STc.

As discussed in FIG. 2 , using the two-way communication channel established between the glasses 10c and the display device 30c of the present invention, many value-added applications can be expanded for the playback system 300 of the present invention. For example, the controller 20c of the glasses 10c can reflect the power supply status of its power supply circuit 14c and/or the operating status of the glasses 10c in the status signal STc, so that the display device 30c can display on-screen (On-Screen Display) The power supply status and/or the operation status of the glasses 10c are prompted to the user. Since the space for the shutter glasses to display their operating status is very limited, most of them can only reflect the simple and basic operating status (such as the status of the power switch) with indicator lights, and it is difficult to display the operating details of the glasses 10c in a friendly and intuitive manner; and , the user must take off the shutter glasses to see the indicator light on the status display. Utilizing the technology of the present invention, the user can directly see the operation details of the glasses 10c on the display 32 without taking off the shutter glasses.

In addition, when the user turns off the power of the glasses 10c and/or when the power supply circuit 14c of the glasses 10c stops supplying power to the lens driver 12c, the transmitting circuit TxGc of the glasses 10c can also transmit its status back to the display device 30c before the power supply is interrupted, so that The display device 30c can automatically terminate or suspend playing the three-dimensional content and switch to the two-dimensional display jointly; or, the display device 30c can also enter an energy-saving standby state thereupon (pausing and/or reducing the impact on the drive circuit 42c, display 32, and video circuit). 34c, the image processing module 36c, the frame buffer 38, the power supply of the transmitting circuit TxDc and/or the control circuit 40c, but maintain the power supply of the receiving circuit RxD), or turn off the power supply (the power supply of the receiving circuit RxD is also terminated). Correspondingly, when the user uses the glasses 10c again (for example, turning on the power switch of the glasses 10c again), the glasses 10c can also actively use the status signal STc to trigger the display device 30c to wake up from the standby state, continue to play the three-dimensional content and/or by The 2D display switches back to 3D display. That is to say, when the user manipulates the glasses 10c, the display device 30c can also automatically perform corresponding operations, which is equivalent to using the glasses 10c to remotely control the display device 30c.

When the display device 30c sends instructions or information to the glasses 10c in its remote control signal Sm, the glasses 10c can also respond with the status signal STc. For example, the playback system 300 can be equipped with a plurality of shutter glasses 10c, and different shutter glasses 10c can each have an identification code built in its memory circuit 24; the display device 30c can send an identification command in the remote control signal Sm, so that Each glasses 10b returns an identification code to the display device 30c. In this way, the display device 30c can identify each pair of glasses, and provide individual services and applications for each pair of glasses. For example, the display device 30c can send polls to different glasses for different identification codes in the remote control signal Sm, so that each glasses can respectively send back its operating status (such as power supply status) to the display device 30c, and The display device 30c can also monitor and/or respond to the operating status of individual glasses. With the remote control signal Sm, the display device 30c can provide corresponding services and applications for each glasses. For example, the display device 30c can record the length of operation of each glasses, the time when the operation starts and ends, and/or the three-dimensional content and viewing progress of each glasses, or carry out content access control, for example, Viewing certain 3D content with certain glasses is prohibited. Alternatively, when the power of a certain glasses is about to run out, the display device 30c can notify the user of the glasses through the speaker of the glasses, but does not disturb the users of other glasses. In addition, the display device 30c can also record some preset operating parameters for each pair of glasses, for example, the preset volume of the speakers of each pair of glasses; speaker to set the preset volume. Compared with the glasses 10c, the display device 30c will have better operating resources (such as more data storage space, faster and better processor, etc.), so it can provide more and better added value for each glasses application. When making the display device 30c identify different glasses, the display device 30c may actively assign the identification codes of the glasses to the glasses. In another embodiment, the display device can also carry sound data and/or vibration data in remote control signals or other wireless signals to be sent to the glasses for reception. The sound waves and sounds emitted by the user through the glasses can enhance user The sense of presence in viewing.

The glasses 10c can also combine the technology of the present invention in FIG. 1 , adding a proximity sensor 22 in the glasses 10c to sense whether the glasses 10c are worn by the user, and provide a corresponding proximity signal SC to the controller 20c. For example, when the proximity sensor 22 senses that the user has taken off the glasses 10c, the controller 20c can not only make the glasses 10c enter the standby state or completely turn off the power supply, but also can stop the power supply to the transmitting circuit TxGc before the power supply circuit 14c stops supplying power to the transmission circuit TxGc. The corresponding state signal STc is sent first, so that the display device 30c can perform adaptive operation, for example, the display device 30c can automatically switch to two-dimensional display, or the display device 30c can also automatically enter the standby state or turn off the power. Of course, the display device 30c can also ask the user, and the user decides the follow-up operation that the display device 30c should perform. In contrast, when the proximity sensor 22 detects that the user wears the glasses 10c again, not only the glasses 10c can be automatically awakened to start operating, but also the status signal STc sent by the transmitting circuit TxGc can be used to control the operation of the display device 30c, such as Wake up the display device 30c from the standby state, make the display device 30c continue the previously paused 3D playback, switch the display device 30c from the previous 2D display to 3D display, and/or prompt the user to indicate the subsequent operation. In other words, the proximity sensor 22 can not only automatically save power consumption for the glasses 10c itself, but also can further control the display device 30c to improve the operating efficiency and application value of the display device 30c.

In one embodiment, if the proximity sensor 22 is realized by a push-type mechanical switch, an appropriate elastic damping can be set on the mechanical switch; when the user takes off the glasses, the elastic damping will keep the mechanical switch temporarily closed. The state of being pressed will not immediately trigger the power supply circuit 14c to stop supplying power, so that the transmitting circuit TxGc has enough time to return the corresponding state signal STc. Alternatively, when the proximity sensor 22 responds with the electronic proximity signal SC that the user has taken off the glasses 10c, the power supply circuit 14c may stop supplying power to the transmitting circuit TxGc after a period of delay, so that the transmitting circuit TxGc has time to activate the glasses 10c. The status is passed back to the display device 30c.

Please refer to Fig. 4 to Fig. 9, what each figure illustrates is the embodiment of various three-dimensional content; As described above, image processing module 36b and 36c (Fig. 2D content is extracted from it to display 3D content in 2D. The 3D content is a 3D image combined with 2D images, and the data corresponding to the 2D images will be recorded in the 3D content in units of scanning lines. For example, multiple pieces of pixel data are recorded in each scanning line, and each pixel data corresponds to the three primary color components of a pixel; by combining the pixel data recorded in each scanning line, the corresponding pictures in the 3D content can be combined. In Fig. 4, the data CO_L(i) and CO_R(i) respectively correspond to a left frame and a right frame to synthesize a three-dimensional image; the data CO_L(i+1) and CO_R(i+1) respectively correspond to The left frame and the right frame of the next 3D image. By playing the 3D images sequentially with the shutter glasses, 3D dynamic images can be presented.

In the embodiment of FIG. 4 , the three-dimensional content carries the data CO_L(i), CO_R(i), CO_L(i+1) and CO_R(i+1) in a frame interleave format; In this format, the data CO_L(i) corresponding to the left frame is recorded on scan lines s(k1), s(k1+1) to s(k1+M-1), and the data corresponding to the right frame in the same 3D image CO_R(i) is recorded on subsequent scan lines s(k2), s(k2+1) to s(k2+M−1). In the next 3D image, the data CO_L(i+1) and CO_R(i+1) corresponding to the left frame and the right frame are sequentially recorded on the scanning lines s(k3) to s(k3+M-1) and s respectively. (k4) to s(k4+M-1), wherein k2 is greater than or equal to (k1+M), k3 is greater than or equal to (k2+M), k4 is greater than or equal to (k3+M), and so on. Scanning lines s(k1) to s(k1+M-1) can be arranged in the same vertical synchronization (horizontal synchronization) cycle; that is, scanning lines s(k1) to s(k1+M-1) can be form a frame. Similarly, the following scan lines s(k2) to s(k2+M-1), scan lines s(k3) to s(k3+M-1) and scan lines s(k4) to s(k4+M-1) -1) can be arranged in the following three vertical synchronization periods respectively.

When the image processing module 36b/36c of the present invention wants to extract two-dimensional content from the three-dimensional content in FIG. Two adjacent frames; each adjacent frame is played sequentially, and two-dimensional dynamic images can be presented without shutter glasses. When the image processing module 36b/36c is running, the format conversion module 54 can temporarily store the left and right frames of the same 3D image (such as the frames corresponding to the data CO_L(i) and CO_R(i)) in the frame buffer from the 3D content In the device 38, the data corresponding to the left frame is transmitted to the scaling module 56 for scaling, so as to be driven and displayed on the display 32 through the driving circuit 42b/42c. Of course, the image processing module 36b/36c can also fixedly select the right frame in the 3D content to form each frame in the 2D content.

In the embodiment of FIG. 5, data CO_Lo(i) and data CO_Le(i) respectively correspond to the odd field (interleaving) and the even field in the left picture; data CO_Ro(i) and data CO_Re( i) respectively correspond to the odd field and the even field in the right picture. In this three-dimensional content format, data CO_Lo(i), CO_Le(i), CO_Ro(i) and CO_Re(i) are sequentially recorded on scan lines s(k1) to s(k1+Mo-1), s( k2) to s(k2+Mo-1), s(k3) to s(k3+Me-1) and s(k4) to s(k4+Me-1), where k2 is greater than or equal to (k1+Mo) , k3 is greater than or equal to (k2+Mo), k4 is greater than or equal to (k3+Me), and so on; and Mo and Me can be the same or different. Scanning lines s(k1) to s(k4+Me) can be arranged in two vertical synchronization periods, wherein, scanning lines s(k1) to s(k2+Mo-1) correspond to the same vertical synchronization period, and scanning line s (k3) to s(k4+Me-1) correspond to the next vertical sync period.

The embodiment of FIG. 5 is applied to the three-dimensional content format of frame packaging and field alternative. When the image processing module 36b/36c of the present invention operates on the 3D content in this format, the data CO_Lo(i) of the scan lines s(k1) to s(k1+Mo-1) and the scan lines s(k3) to s The data CO_Le(i) of (k3+Me−1) is combined to form the left frame corresponding data CO_L(i) to form a frame in the 2D content.

The embodiment in FIG. 6 is to record the left and right images in the 3D content in a line alternative manner. The left frame data CO_L(i) corresponding to the same 3D image will be recorded on scan lines s(k), s(k+2), s(k+4) to s(k) at intervals of one scan line. +2*M-2), and the data CO_R(i) corresponding to the right picture is alternately recorded on scanning lines s(k+1), s(k+3), s(k+5) to s(k+ 2*M-1). The scan lines s(k) to s(k+2*M−1) can be arranged in the same vertical sync period. When the image processing module 36b/36c of the present invention operates on three-dimensional content in this format, it can scan lines s(k), s(k+2), s(k+4) and so on to s(k+2*M- 2) Combining the data CO_L(i) corresponding to the left frame to form a frame in the 2D content.

The embodiment in FIG. 7 records 3D content in a side by side format. Each scan line in the 3D content is divided into front and rear segments, and each segment corresponds to multiple pixels; for example, the scan line s(k) is divided into scan line segments s(k)a and s(k)b , the scan line s(k+1) is divided into scan line segments s(k+1)a and s(k+1)b, and so on. The left frame data CO_L(i) corresponding to the same 3D image will be respectively recorded in the scan line segments s(k)a, s(k+1)a to s(k+M-1)a, corresponding to the right frame data CO_R(i) is recorded in scan line segments s(k)b, s(k+1)b to s(k+M-1)b. The scan lines s(k) to s(k+M−1) can be arranged in the same vertical sync period. When the image processing module 36b/36c of the present invention operates on 3D content in this format, it can be retrieved from scan line segments s(k)a, s(k+1)a to s(k+M-1)a The left frame corresponding to the data CO_L(i) forms two-dimensional content.

The embodiment in FIG. 8 records three-dimensional content in an up and down (or top and bottom) format. In the same 3D image, the data CO_L(i) and CO_R(i) corresponding to the left frame and the right frame are respectively recorded in the scan lines s(k1) to s(k1+M1-1), and the subsequent scan line s(k2 ) to s(k2+M2-1); where k2 is greater than (k1+M-1), M1 can be equal to M2, and scanning lines s(k1) to s(k2+M2-1) can be arranged in the same vertical synchronization cycle. For this 3D content format, the image processing module 36b/36c of the present invention can retrieve the left frame corresponding to the data CO_L(i) from the scan lines s(k1) to s(k1+M1-1) to form 2D content.

In the embodiment of FIG. 9, each 3D image in the 3D content is formed by data CO_L(i) combined with a depth data CO_D(i). The left and right frames in the 3D image can be formed by the data CO_L(i) and depth data CO_D(i) is calculated, while data CO_L(i) is recorded on scan lines s(k1) to s(k1+M1-1), and depth data CO_D(i) is recorded on scan lines s(k2) to s(k2+M2-1), where k2 is greater than (k1+M-1), and the scanning lines s(k1) to s(k2+M2-1) can be arranged in the same vertical synchronization period. For this kind of three-dimensional content format, the content processing module 36b/36c of the present invention can first obtain the data corresponding to the left and right pictures from the scan line s(k1) to s(k2+M2-1), and fix it in the left and right pictures to select one of them One to form two-dimensional content.

In the embodiments shown in FIG. 4 to FIG. 9 , the total number of pixel data in each scan line/scan line segment is not necessarily equal to the number of pixels on the full screen of the display 32 ( FIG. 2 / FIG. 3 ). For example, the resolution of the display 32 may be 1920*1080, that is, there are 1920 pixels in the horizontal direction and 1080 pixels in the vertical direction. However, in the embodiment of FIG. 7, each scan line segment may only have 960 pieces of pixel data, and the data CO_L(i) and data CO_R(i) are recorded in 1080 scan line segments respectively (that is, M=1080 in FIG. 7 ). . When the display 32 is to display the image corresponding to the data CO_L(i) (or CO_R(i)) in a full-screen two-dimensional manner, the scaling module 56 can perform appropriate related interpolation and/or scaling processing (such as horizontal scaling) to Based on 980 pixel data on 1080 scan line segments, the full screen resolution of 1920*1080 is expanded.

Similarly, in the embodiment of FIG. 8 , the data CO_L(i) and CO_R(i) can be respectively recorded in 540 scan lines (ie M=Mt=540), and each scan line contains 1920 pieces of pixel data. Therefore, when the picture corresponding to the data CO_L(i) (or CO_R(i)) is displayed two-dimensionally, the scaling module 56 will also perform scaling processing (such as vertical scaling) so as to use the full screen resolution of 1920*1080 Dimensional display data CO_L(i) (or CO_R(i)) corresponds to the screen.

To sum up, compared with the known playback system, the 3D content playback system of the present invention can improve the performance and application value of the shutter glasses itself by using the proximity sensor installed on the glasses end, and can also cooperate with the two-way communication between the glasses and the display device The pipeline provides many value-added applications for the entire playback system. In another type of embodiment, the present invention can also provide many value-added applications for the playback system by using the image capture device and the recognition module at the display device side. The above-mentioned value-added applications can improve the performance of the playback system, save unnecessary power consumption, and allow users to use the playback system more intuitively and conveniently.

The above-mentioned various embodiments of the present invention can also be applied to 2D display, which extracts 2D content from 3D content according to the spirit of the present invention, and displays it in 2D. It can be applied to a 2D display device without 3D display capability, so that the 2D display device can be compatible with the 3D content provided by the 3D source, and display the 3D content in 2D correctly and comfortably. The 2D display device of an embodiment may include a display and an image processing module, capable of extracting 2D content from 3D content in various formats for display. The image processing module in this example includes a format judgment module, a format conversion module and a scaling module. The format judging module judges which format is used to carry the left frame and the right frame of the 3D image in the 3D content, and the format converting module can fixedly select the left frame of each 3D image to form the 2D content and play it. The scaling module is used for appropriately scaling each picture horizontally and/or vertically, so that each picture can conform to the resolution of the display. The image processing module of the present invention can be integrated with the control circuit of the display device in the same chip, for example, the microcontroller in the chip executes firmware and/or software program codes to realize the control circuit and the image processing module.

In summary, although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Anyone familiar with the technical field may make various modifications without departing from the spirit and scope of the present invention.
