Description

Image display remote controller, remote controller system and processing method thereof

technical field

The present invention relates to a photographic device, and in particular to a remote controller capable of displaying real-time images captured by the photographic device, a remote controller system and a processing method thereof.

Background technique

When the photographer uses the camera to take pictures, he can control the camera to take pictures of himself by utilizing the remote controller of the camera. Usually photographers need to observe behind the lens of the camera and adjust the lens to frame the view. After the photographer has finished adjusting the composition, use the remote control of the camera to shoot before moving to the lens. The camera remote control enables the camera user to take a selfie of himself without the assistance of others, and can also replace the regular photo taking function of the camera.

Because when the photographer leaves the camera and arrives in front of the lens, he cannot see the framing in the camera lens. So photographers usually don't adjust the lens when they move to the front of the lens. Therefore, the remote control is usually only used to control the camera's shutter opening and closing and exposure operations.

For example, in the current camera remote controllers, although some remote controllers have the function of controlling the zoom of the camera. However, this function cannot be effectively utilized because the photographer cannot see the framing in the camera lens when reaching the front of the lens after leaving the camera.

In addition, for a camera with a rotatable lens or a rotatable LCD screen, after the lens or LCD screen is adjusted, the photographer can see the viewfinder in the camera lens when he reaches the front of the lens. However, since the size of the LCD screen is usually small, as the distance between the photographer and the camera is extended, the photographer cannot clearly see the image in the LCD screen. In the occasion of group photo taking with a large number of people, because the photographer will be far away from the camera if he is in the crowd being photographed. Therefore, this type of camera cannot successfully compose a selfie by observing the display of the camera in a large group photo occasion.

The remote control of a traditional camera provides great convenience in controlling the camera's framing exposure, but fails to provide related functions for assisting composition. Therefore, even if the camera remote control provides various adjustment functions, such as a zoom function, in terms of controlling the function of the camera lens, the provided functions cannot be effectively utilized, and thus are useless.

Therefore, when the photographer is shooting a group or individual including himself, if he needs to adjust the composition or viewfinder, he still has to go back to the camera for adjustment. This point is just the inconvenience that can be caused in traditional cameras and remote controls.

Therefore, there is a need for a camera remote control system capable of displaying real-time images obtained by the camera on the remote control, so as to solve the problem of composition when photographers are shooting groups or individuals including themselves.

The input unit 4 is used for generating a zoom signal or a shooting signal according to a user's operation. The communication unit 2 is used for sending a zoom signal or a shooting signal to the camera 20 and receiving image data from the camera 20 . The processor 1 is used to process the image data and output it to the display 3 for display.

FIG. 4 shows the flow chart of the operation of the camera 20 and the remote controller 10 according to the preferred embodiment of the present invention. First, the remote controller 10 establishes a wireless connection with the camera 20 (step S1 ), and the camera 20 establishes a wireless connection with the remote controller 10 (step S2 ). In this embodiment, digital signals are used to transmit image data between the camera 20 and the remote controller 10 . In a preferred embodiment of the present invention, although the camera 20 and the remote controller 10 transmit image data with digital signals, it is not intended to limit the present invention. The camera 20 and the remote controller 10 can also transmit image data using analog signals. In the case of transmitting image data with analog signals, for example, the image capture unit 23 obtains the image data and converts the image data into radio frequency (Radio Frequency) signals to be sent to the remote controller 10 .

During the establishment of the wireless connection, the camera 20 and the remote controller 10 need to tune in frequency. For example, the camera 20 sends out a fixed-frequency beacon, and the remote controller 10 searches for the beacon. When the remote controller 10 searches for a beacon, it communicates with the camera 20 at the above-mentioned fixed frequency. Although wireless communication is performed at a fixed frequency in a preferred embodiment of the present invention, it is not intended to limit the present invention. The camera 20 and the remote controller 10 can also communicate wirelessly by using frequency-hopping (Frequency-Hopping) technology.

Next, the image capturing unit in the camera 20 captures the image data 30 (step S4 ) and transmits the image data 30 to the processing unit 21 . The processing unit 21 processes the image data 30 captured by the image capturing unit (step S5). In a preferred embodiment of the present invention, during the image processing process, the processing unit 21 samples image data and performs analog-to-digital conversion on the sampled data. The processing unit 21 divides the converted digital image data into multiple data frames, and compresses the multiple data frames. Then the processing unit 21 transmits the compressed data frame to the communication unit 22 for transmission. However, the above-mentioned image processing program is not intended to limit the present invention. For example, the camera 20 can also directly compress the image data and send it out without dividing the converted digital image data into multiple data frames. In other embodiments, analog-to-digital conversion may not be required.

The communication unit 22 in the camera 20 captures the compressed image data 30 and transmits the compressed image data 30 to the remote controller 10 via wireless communication by sending the compressed complex data frames to the remote controller 10 (step S6 ). The camera 20 keeps repeating the operations of capturing image data, processing image data and transmitting image data.

The remote controller 10 receives the compressed data frames via the communication unit 2 to receive the image data 30 (step S10 ). The communication unit 2 transmits the received compressed complex data frame in which the image data is recorded to the processing unit 1 .

The processing unit 1 in the remote controller 10 processes the image data 30 (step S12). During the image processing, the processing unit 1 decompresses the received compressed complex data frame, and reassembles the decompressed data frame into the digital image data 30 . In other embodiments, if the image data 30 is not divided into multiple data frames, the processing unit 1 in the remote controller 10 directly decompresses the received compressed image data into the image data 30 during processing the image data 30 .

In this embodiment, the display 3 is a display capable of receiving digital image data. The processing unit 1 outputs the processed digital image data 30 to the display 3 . The display 3 displays the video content recorded in the video data 30 (step S14).

It should be noted that in the preferred embodiment of the present invention, although the display 3 is a display capable of receiving digital image data, it is not intended to limit the present invention. Therefore, an analog display can also be used. In the case of using an analog display, the processing unit 1 needs to convert the digital image data into analog image data, and then input the analog image data to the analog display.

The remote control 10 of the preferred embodiment of the present invention can display the image captured by the camera 20 in real time, so when the user of the remote control 10 is shooting a group or individual including himself, it can help the user compose the picture. When the remote control 10 provides the function of adjusting the camera 20 to take images, the remote control 10 can also display the real-time images captured by the camera 20 after being adjusted in real time. Next, taking the remote control 10 with a zoom function as an example, the operation between the remote control 10 and the camera 20 will be described. Although the zoom function is used as an example in this embodiment, it is not intended to limit the present invention, and similar operations can also be applied to other functions of adjusting the camera.

When the user operates the input unit 4 , the input unit 4 generates a zoom signal 40 . After the zoom signal 40 is input to the processing unit 1, the processing unit 1 transmits the zoom signal 40 to the camera 20 via the communication unit 2 (step S16).

After the camera 20 receives the zoom control signal 40 (step S18 ), the processing unit 21 in the camera 20 adjusts the focal length of the lens via the focus adjustment unit 24 according to the zoom control signal 40 (step S20 ). During the adjustment process of the lens focal length, the image capturing unit 23 captures the image during the zooming process. And the image data during the zooming process is transmitted by the processing unit 21 to the remote controller 10 via the communication unit 22 . After the lens focal length is adjusted, the image capture unit 23 captures the zoomed image (step S22 ) and transmits the zoomed image data 31 to the processing unit 21 . The processing unit 21 processes the zoomed image data 31 (step S24). The communication unit 22 transmits the zoomed image data 31 processed by the processing unit 21 to the remote controller 10 (step S26 ).

The communication unit 2 of the remote controller 10 receives the zoomed image data 31 (step S28 ) and transmits the received zoomed image data 31 to the processing unit 1 . The processing unit 1 processes the zoomed image data 31 (step S30 ), and transmits the processed zoomed image data 31 to the display 3 . The display 3 displays the zoomed image data 31 processed by the processing unit 1 (step S32).

Thus, the remote controller 10 can display the real-time image captured by the camera 20 on the display 3 for reference by the user. The user can adjust the focus of the camera 20 according to the real-time image displayed on the display 3 .
