Patent Images
1. A moving image processing system comprising:
- a) a moving image signal recording apparatus having recording means for recording a moving image signal on a recording medium;
b) extracting means for extracting a still image from said moving image signal to be recorded by said recording means in response to a start of recording of said moving image signal by said recording means;
c) compressing means for compressing the still image extracted by said extracting means; and
d) an external storage device which receives the still image compressed by said compressing means and is able to store still images corresponding to a plurality of pictures, said external storage device being removably attached to said recording apparatus.

Abstract
A system facilitates a search operation and managing work on video signals having a numerous amount of information such as signals for moving images by removably mounting, on a video camera or a video signal recording device, a storage device for storing a specified picture or pictures included in the moving images. The system is arranged to extract the specified picture from the moving images for every given period of time, so that a video signal having a numerous amount of information can be searched without any difficulty.
