The present invention relates to a system for storing and reproducing a panoramic image. More specifically, the panorama memory function is implemented by controlling the frame memory when shooting or displaying a video movie camera. The present invention relates to a panorama image storage and reproducing system that can provide a more interesting and useful image with vivid image quality when shooting.

When playing video signals shot with a video movie camera and viewing them on a monitor, the video cassette recorder (VCR) 's special playback function allows the user to view a certain part of the video on a still or slow screen.

The special playback function of the video cassette recorder (VCR) is to allow the video cassette recorder (VCR) deck to view the image on the screen obtained through the stop or slow speed through the mechanical control of the tape running speed. .

However, the above-described conventional technology has a problem that the screen is considerably deteriorated due to mechanical limitations, so that it is difficult for a user to obtain a clear screen, and only a continuous frame image can be played back at a slow screen playback.

Therefore, if you want to take special effects such as continuous shooting of several frames per second, which you can achieve by applying the panorama shooting function to some still cameras for still images of high-end type using a movie camera, It can only be obtained through editing with an editor.

Accordingly, an object of the present invention is to solve the above-described problems, and not to control the traveling speed of a video cassette recorder (VCR) tape, but to control the frame memory when shooting or displaying in a video movie camera. By implementing the shooting function, it is to provide a panorama image storage and playback system that can provide a more interesting and useful video with clear picture quality when shooting a continuous motion of sports such as tennis, golf.

As a means for achieving the above object, the configuration of the present invention comprises: a charge coupling element for converting the brightness of the subject into a charge to produce an electrical signal; An analog-digital converter for converting a continuous analog signal into a digital signal; A camera image signal processor for converting the digitalized image signal into a luminance signal and a color difference signal; A frame memory for storing the luminance signal and the color difference signal output from the camera image signal processor in units of frames; A memory controller configured to control read and write timing of the frame memory according to a user setting mode; A signal converter for receiving a luminance signal and a color difference signal directly output from the camera image signal processor and a luminance signal and a color difference signal output through the frame memory, and converting a signal by a control signal output from the memory controller; It consists of encoders that produce color video image signals that conform to each broadcast standard.

By the above configuration, the most preferred embodiment that can be easily carried out by those skilled in the art with reference to the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the configuration of the system for storing and reproducing a panoramic image according to an embodiment of the present invention is

A charge coupling device 1 for converting the brightness of the subject into electric charges to produce an electrical signal; An analog-to-digital converter (2) which receives a continuous analog signal output from the charge coupling device (1), converts it into a digital signal and outputs the digital signal; A camera image signal processor (3) which receives the digitalized image signal from the analog-to-digital converter (2), converts it into a luminance signal and a chrominance signal, and outputs the converted signal; A frame memory (4) for receiving the luminance signal (Y) and the color difference signals (Cr, Cb) output from the camera image signal processor (3) and storing them in units of frames; A memory controller (5) for controlling the read and write timing of the frame memory (4) in accordance with a user setting mode; A signal converter for receiving a luminance signal and a color difference signal output directly from the camera image signal processor 3 and a luminance signal and a color difference signal output from the frame memory 4, respectively, and converting and outputting a signal by a control signal ( 6); The encoder 7 is configured to receive a signal output from the signal converter 6 and to produce a color video image signal conforming to each broadcasting standard.

The operation of the system for storing and reproducing a panoramic image according to the embodiment of the present invention according to the above configuration is as follows.

The charge coupling device 1 converts the brightness of the subject into a charge to generate an electrical signal.

The analog-to-digital converter 2 receives a continuous analog signal output from the charge coupling device 1, converts it into a digital signal, and outputs the digital signal.

The camera image signal processor 3 converts the image signal digitalized by the analog-digital converter 2 into a luminance signal Y and a color difference signal Cr, Cb and outputs the same.

The frame memory 4 receives the luminance signal Y and the color difference signals Cr and Cb output from the camera image signal processor 3 and stores them in units of frames.

The memory controller 5 controls the read and write timing of the frame memory 4 according to a user setting mode.

The signal converter 6 receives the luminance signal Y and the color difference signals Cr and Cb output directly from the camera image signal processor 3 and the luminance signal and the color difference signal output from the frame memory 4, respectively. The function of the multiplexer switches the signal by the control signal and outputs the signal.

The encoder 7 receives a signal output from the signal converter 6, generates and outputs a color video image signal conforming to each broadcasting standard.

First, the luminance signal and the chrominance signal output from the camera image signal processor 3 start the panorama special shooting mode so that the divided screen of the size set by the user is controlled by the control of the write timing of the memory controller 5. The frame memory is set by the user by decimating the video signal and storing it in an area of a part of the frame memory 4, and then storing a frame after a time set by the user in the next area of the frame memory. The video signal is stored repeatedly until all of them are stored in one split screen.

While the divided screen is stored in the frame memory 4, a path in which the original image signal currently input through the charge coupling device 1 is directly connected to the signal converter 6 through the camera image signal processor 3. After the output of the panoramic image of the frame memory 4 is finished, the panoramic image of the user setting interval is output from the frame from then on, and the panoramic image output in this way is after a certain time, The screen returns to the original image.

This panorama function is particularly useful for shooting continuous shooting in sports modes such as tennis and golf, and it is also possible to adjust the aspect ratio of the decimation when saving to the frame memory (4). You can get it.

As described above, in the embodiment of the present invention, when shooting or displaying in a video movie camera, by controlling the frame memory, by implementing a panorama shooting function, it is more interesting and useful when shooting a continuous motion of sports such as tennis, golf It is possible to provide a system for storing and reproducing a panoramic image having an effect of displaying an image with a clear image quality.
