ABSTRACT:
A method and an apparatus for image processing capable of solving the problem of out of standard image signals, with a least amount of a deterioration of the image quality and a distortion of the image produced at the central region of the image. In this apparatus, the out of standard image signals having missing portions are treated by a horizontal blanking width correction process in which only those parts of the video signals corresponding to horizontally peripheral regions of the image are enlarged to supplement the missing portions of the video signals, and then the parts of the video signals corresponding to the central region of the image and the horizontally peripheral regions of the image are combined to obtain full video signals without missing portions.
