ABSTRACT:
An image movement detecting apparatus for use with a television camera. An image is inputted from the television camera at intervals of time. The image is scanned in a series of scan lines to detect a pixel in each of the scan lines, the detected pixel forming an edge point in the image. The image processing apparatus calculates values each of which indicates a distance between detected pixels forming the same edge point in new and last images inputted successively. The calculated values are averaged to calculate a movement of the new image with respect to the last image. The calculated movement is added to a movement of the last image with respect to a reference image having no influence of movement of the television camera to calculate a total movement of the new image with respect to the reference image.
