<p><P>PROBLEM TO BE SOLVED: To provide video processing apparatus in which a video signal is digitally compressed as a moving picture and the video data is sent to a CPU or a storage medium, and also the compressed video data from the CPU or the storage medium is digitally expanded and at the same time the moving picture can be displayed on a monitor screen at an arbitrary position and in arbitrarily enlarged or reduced size. <P>SOLUTION: In the video processing apparatus, an isolation circuit is positioned between an AD converter and a video memory and between a video code expansion circuit and the video memory, the video signal is displayed on the monitor screen in arbitrarily enlarged or reduced size and at the same time the video data produced by a code compression of the video signal is stored in a computer, etc., and also a code expansion of the data which is produced by a code compression of the video signal and sent from the computer, etc. is performed and the video can be displayed on the monitor screen in arbitrarily enlarged or reduced size. <P>COPYRIGHT: (C)2004,JPO</p> |
