1. A motion information generating apparatus for generating data indicative of motion of a predetermined portion of an image in a series of video picture frames formed of image data and displayed on a video monitor receiver, comprising:
- designating means for designating a one-dimensional segment of each frame of said series of video picture frames successively displayed on said video monitor receiver, said one-dimensional segment extending across said predetermined portion of said image;
digital memory means for storing digital image data of said series of video picture frames;
means for reading out from said memory means digital image data corresponding to said predetermined portion for each frame of a consecutive series of video picture frames and said one-dimensional segment of said frame designated by said designating means; and
image processing means for processing said image data read out from said means for reading out and producing therefrom an information signal indicating motion of an edge in said predetermined portion of said image on the basis of image data in said series of video picture frames.

3. A motion information generating apparatus for generating data indicative of motion of a predetermined portion of an image in a series of video picture frames formed of image data and displayed on a video monitor receiver, comprising:
-
first memory means for storing therein and reading out therefrom digital image data of one frame of said series of video picture frames supplied from a video signal source; designating means for designating a one-dimensional segment of the one frame of said series of video picture frames stored in said first memory means, said segment extending across said predetermined portion of the image displayed on said video monitor receiver; means for reading out from said first memory means image data corresponding to said predetermined portion for each frame of a consecutive series of said video picture frames and said one-dimensional segment of said one frame designated by said designating means; image processing means for processing said image data read out from said means for reading out and producing therefrom a digital information signal indicating motion of an edge in said predetermined portion of said image on the basis of said image data in said consecutive series of video picture frames; and second memory means for storing therein said digital information signal produced by said image processing means. - View Dependent Claims (4, 5)
