ABSTRACT:
An image processing apparatus extracts a local image from an original image which is supplied by an image input unit, the local image corresponding to a local area, designated by a coordinate data input unit, and being supplied to an image output unit. The apparatus extracts local image data by using coordinate data associated with boundary pixels positioned in boundary lines between the local image and other parts of the original image. The extracted local image data are then provided to the image output unit in accordance with horizontal and vertical synchronizing signals applied from a generator.
