ABSTRACT:
An image processing apparatus converts an interlaced signal including a signal converted so as to be matched to a frame rate of an input video signal with original images arranged on a basis of a predetermined sequence as the video signal into a progressive signal. The image processing apparatus includes a field-interpolated signal generator generating a progressive field-interpolated signal by interpolating a signal at a selected position corresponding to a scanning line to be interpolated in a present field, the signal at the selected position belonging to one of a field preceding the present field and a field succeeding the present field; and a double image detector determining whether a pixel in the field-interpolated signal forms a part of a double image, and replacing a pixel in the field-interpolated signal which forms a part of a double image in the field-interpolated signal with a predetermined substitute signal.
