Abstract

PURPOSE:To obtain a satisfactory picture by increasing the information volume as much as possible at the time when the picture photographed by a wide angle lens with a CCD image pickup element having a large number of picture elements is appreciated in the high vision size. CONSTITUTION:The picture having an ordinary television size 1 is trimmed to a high vision size 3, and it is left as it is in the vertical direction but is compressed to the ordinary television size only in the horizontal direction by the digital video processing. At the time of reproducing, the picture is left as it is in the vertical direction but is enlarged to the high vision size only in the horizontal direction by the digital video processing so that it can be appreciated.

Description

The present invention relates to a video tape recorder with a video camera and a video device.

[Prior Art] Conventional videotape recorders with video cameras and video equipment are usually recorded and reproduced by cutting the upper and lower sides of a TV size with black masking when trimming to a high-definition size.

[Problems to be Solved by the Invention] In the conventional video tape recorder and video equipment with a video camera as described above, when the normal TV size is trimmed to the high-definition size, the upper and lower parts are masked by black masking so that the amount of information on the screen is also masked. Is cut by the amount of, and the screen becomes unclear when viewed on a high-definition TV or projector.

[Means for Solving Problems] In order to solve the above problems, the present invention uses a CCD image pickup device having as many pixels as possible to trim an image taken by a wide-angle lens to a high-vision size. Then, by digital image processing, only the horizontal direction is compressed to the normal TV size while recording in the vertical direction, and 100% of the amount of information that can be recorded on the video tape is used to convert the normal TV size to the high-definition size. This is a device that minimizes the reduction in the amount of information that sometimes occurs.

[Sayo] The present invention has the above-mentioned configuration, and is a video device for recording and reproducing a normal TV size, in which a high-definition size image is compressed in the vertical direction as it is by a digital image processing, and is once a normal TV size. By recording back in full frame and returning to high definition size by digital video processing during playback, you can get a wide screen normal image that is wider than ordinary TV size. By the above method, not only the image of the video tape recorder with the video camera but also the high-definition size software and the wide size movie software can be clearly viewed by the above recording / playback method.

[Embodiment] In FIG. 1, 1 is an entire screen of a normal TV size, 2 is a portion to be cut for trimming to a high-definition size, 3 is a trimmed high-definition size screen, and 4 is a picture taken on a high-definition size screen. The three round circles that were made. In FIG. 2, 5 is a high-definition-size image compressed by digital image processing in the vertical direction as it is and compressed only in the horizontal direction to a normal TV size
An image of a full frame recorded on a video device is an elliptical circle. Fig. 3 shows an image enlarged to the high-definition size only in the horizontal direction while maintaining the vertical direction by digital image processing again. This makes it possible to use 100% of the information capacity of video equipment when viewing on a high-definition television or projector.

[Brief description of drawings]

Fig. 1 shows a high-definition image that is trimmed to a normal TV size and has three regular circles on the screen. In Fig. 2, the high-definition size is compressed to the TV size only in the horizontal direction, so the regular circle is a vertically elongated ellipse. In Fig. 3, the TV size is enlarged to the high-definition size only in the horizontal direction, so the ellipse is back to a perfect circle.

Claims (1)

[Claims] In video tape recorders and video equipment with video cameras that convert video and audio into electrical signals for recording and playback,
We use a CCD image sensor with a high number of pixels, take a picture with a wide-angle lens, trim this from a normal TV size to a high-definition size, and compress it to the TV size only in the horizontal direction at the same ratio in the vertical direction by digital image processing. A device that allows you to record and play back digital images once again in the vertical direction, but only in the horizontal direction for high-definition viewing.
