Detailed ways

Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

The camera device of the present invention may be an independent digital camera, or may be realized by an electronic device with a camera function. For example: notebook computer (notebook), mobile phone (mobilephone) or digital personal assistant (PersonalDigitalAssistant, PDA) and so on. In order to clearly illustrate the difference between different camera devices in the present invention, one of them is defined as the master camera device 110 , and the other camera devices are defined as the slave camera devices 120 . Please refer to FIG. 1A , which is a schematic diagram of the architecture of the present invention.

The main camera device 110 has a first camera unit 111 , a first processing unit 112 , a first storage unit 113 and a first transmission unit 114 . The first processing unit 112 is electrically connected to the first camera unit 111 , the first storage unit 113 and the first transmission unit 114 , as shown in FIG. 1B . The first camera unit 111 is used for shooting digital images. The first camera unit 111 may be implemented by a Charge-coupled Device (CCD) or a Complementary Metal Oxide-Semiconductor (CMOS). The first processing unit 112 stores the captured digital images in the first storage unit 113 .

The first storage unit 113 of the present invention is further divided into a personal image area 116 and an image sharing area 115 . Besides the capacity of the personal image area 116 and the image sharing area 115 can be determined by the preset value, it can also be determined by the user. The first storage unit 113 can be different according to different imaging devices, for example: the imaging device is a digital camera, then the first storage unit 113 can be a memory card; if the imaging device is a notebook computer, then the first storage unit 113 can be For hard disk or pen drive. Both the personal image area 116 and the image sharing area 115 can store digital images.

When the digital images are stored in the image sharing area 115, other camera devices can view the digital images shared by other camera devices through the transmission method described later. And the digital images in the personal image area 116 can only be viewed by the camera device at the local end. For example, if the digital image A is stored in the personal image area 116 of the master camera device 110 , the slave camera device 120 cannot view the digital image A.

Similarly, the slave camera device 120 has at least a second processing unit 122 , a second storage unit 123 and a second transmission unit 124 , and a second camera unit 121 can be optionally provided. The second processing unit 122 is electrically connected to the second camera unit 121 , the second storage unit 123 and the second transmission unit 124 . The second storage unit 123 is also divided into an image sharing area 125 and a personal image area 126 .

The slave camera 120 can transmit data with the first transmission unit 114 of the master camera 110 through the second transmission unit 124 . In the present invention, wireless transmission is used as an illustration. The transmission types of the first transmission unit 114 and the second transmission unit 124 can be but not limited to IEEE802.11 series, Bluetooth wireless transmission, ultra-wideband wireless transmission, third-generation mobile communication technology, Worldwide Interoperability for Microwave Access, WiMAX (IEEE802.16a)) or LTE (LongTernEvolution) (3GPP long-term evolution technology LongTernEvolution, LTE).

In order to clearly illustrate the operation process of the present invention, please also refer to FIG. 2 , which is a schematic diagram of the operation process of the present invention. The shared transmission method of the present invention includes:

Step S210: dividing the storage unit of the master camera device and the slave camera device into an image sharing area and a personal image area;

Step S220: The master camera device acquires the capacity of the image sharing area of other slave camera devices;

Step S230: Connect all the image sharing areas of the slave camera device and the master camera device to form a virtual shared area;

Step S240: the master camera device and the slave camera device mount the virtual shared area; and

Step S250 : When the master camera device or the slave camera device shoots digital images and stores the digital images in the virtual shared area, then transmit the digital images to the image shared area of other camera devices.

Firstly, the storage unit of each camera device is divided into shared image areas 115 , 125 and personal image areas 116 , 126 . After the master camera device 110 is connected to other slave camera devices 120 , the capacity of each image sharing area 115 and 125 is obtained. The main camera device 110 sequentially connects each image sharing area 115 , 125 according to the connection sequence of the slave camera devices 120 to form a virtual sharing area 340 . Therefore, no matter the main camera device 110 or the slave camera device 120 can see the virtual shared area 340 in its own operating system. For the master camera 110 or the slave camera 120 , the virtual shared area 340 seen has the same capacity. Therefore, the process of writing files by the master camera 110 or the slave camera 120 can be regarded as a seamless process. In addition, during the process of connecting the slave camera device 120 to the main camera device 110 , account and password verification settings can also be added, so as to prevent unknown users from stealing digital images.

Please refer to FIG. 3 , which is a schematic diagram of connection of each image sharing area of the present invention. Assume that there is one master camera 310 and two slave cameras 120 (respectively the slave camera 320 and the slave camera 330 ) in FIG. 3 . The first storage unit 311 of the main camera 310 is divided into an image sharing area A1 and a personal image area P1. The second storage unit 321 of the camera device 320 is divided into an image sharing area B1 and a personal image area P2. The third storage unit 331 of the camera device 330 is divided into an image sharing area C1 and a personal image area P3 . The master camera device 310 is connected to the slave camera device 320 and the slave camera device 330, and the image sharing area A1, the image sharing area B1, and the image sharing area C1 are concatenated, and the concatenated storage space is defined as a virtual shared area 340 .

Since the virtual sharing area 340 is composed of the image sharing area A1, the image sharing area B1 and the image sharing area C1, the capacity of the virtual sharing area 340 is the sum of the image sharing area A1, the image sharing area B1 and the image sharing area C1.

After completing the setting of the virtual shared area 340 , the master camera 310 , the slave camera 330 and the slave camera 330 will mount the virtual shared area 340 . Therefore, the master camera device 310 , the slave camera device 320 and the slave camera device 330 can all access the contents of the virtual shared area 340 . For the access process of each camera device to the virtual shared area 340 , please also refer to FIG. 4A , which is a schematic diagram of a digital image transmission operation flow of the present invention.

Step S411: Generate a preview icon according to the captured digital image, and transmit the preview icon to the image sharing area of other camera devices; and

Step S412: After other camera devices select the preview icon from the image sharing area, the camera device that shoots the digital image transmits the digital image to the camera device that selects the preview icon.

Assume that after the main camera device 310 shoots a digital image, the main camera device 310 stores the digital image in the image sharing area A1 to which it belongs. The first processing unit 112 generates a corresponding preview icon 422 according to the digital image (herein defined as the original image 421 ), as shown in FIG. 4B . The image size or resolution of the preview icon 422 is smaller than the image size or resolution of the original image 421 . After the first processing unit 112 generates the preview icon 422, the first processing unit 112 will transmit the preview icon 422 to the image sharing areas B1 and C1 of the slave camera device 320 and the slave camera device 330 through the first transmission unit 114 or The preview icon 422 is only transmitted when the virtual shared area 340 is browsed from the camera device 320 and from the camera device 330 . Therefore, the slave camera device 320 and the slave camera device 330 can watch the digital image captured by the main camera device 310 from the virtual shared area 340 .

When the slave camera 320 selects any preview icon 422 from the virtual shared area 340 , the second processing unit 122 will send a request to the master camera 310 for the original image 421 . When the master camera device 310 receives a request, the master camera device 310 will transmit the digital image to the slave camera device 320 . Finally, the slave camera 320 records the digital image in the personal image area P2, as shown in FIG. 4C. In the same way, for the slave camera 320, the photo preview icon 422 taken by this machine can also be transmitted to other camera devices (such as the master camera 310 or the slave camera 330) or to other camera devices in this way. The transmission is only performed when browsing the virtual shared area 340 .

In addition to the above-mentioned transmission methods, the present invention can also access the contents of the virtual shared area 340 in the following ways. Please refer to FIG. 5 , which is a schematic diagram of another digital image transmission operation flow of the present invention.

Step S511: the camera device records the digital image in its associated image sharing area, and the camera device transmits the digital image to other camera devices;

Step S512: After receiving the digital image, other camera devices record the digital image in the image sharing area to which they belong; and

Step S513: When any digital image is selected in the virtual shared area of other camera devices, the camera device records the selected digital image in the personal image area.

Assume that after the main camera device 310 shoots a digital image, the main camera device 310 stores the digital image in the image sharing area A1 to which it belongs. The master camera device 310 directly transmits the digital image to the other slave camera devices 320 and 330 . The slave camera device 320 and the slave camera device 330 first store the digital images in the image sharing areas B1 and C1. When the user selects any digital image from the virtual shared area 340 of the secondary camera device 320 and the secondary camera device 330, the secondary camera device 320 and the secondary camera device 330 will move the selected digital image to the personal image area P2, P3 among.

In addition to the above purposes, the virtual shared area 340 of the present invention can also be used as a temporary storage device. When all camera devices are connected, first obtain the capacity of the image sharing area A1, B1, and C1 of each camera device. The images are sent to the image sharing areas A1 , B1 , and C1 belonging to other camera devices in the virtual sharing area 340 and have sufficient capacity for storage. For example, when the personal image area P1 of the main camera device 310 has insufficient space, the user can store the digital image in the virtual shared area 340 after shooting. At the same time, the master camera 310 will store the digital image in the image sharing area P2 (or P3 ) of the other slave cameras 320 (or 330 ).

The method and system for transmitting shared digital images to multiple photographic devices proposed by the present invention can transmit the digital images to other photographic devices in real time after any digital image is captured by any photographic device.

Of course, the present invention can also have other various embodiments, and those skilled in the art can make various corresponding changes and deformations according to the present invention without departing from the spirit and essence of the present invention, but these corresponding Changes and deformations should belong to the scope of protection of the appended claims of the present invention.
