Abstract:
1. An image signal processing apparatus configured to convert an interlaced signal into a progressive signal, comprising: a first conversion unit configured to convert the interlaced signal into a progressive signal by 2·2 pull-down inverse conversion; a second conversion unit configured to convert the interlaced signal into a progressive signal by motion adaptive IP conversion; a decision unit configured to arithmetically operate a correlation value of two successive field images of the interlaced signal and decide based on the correlation value whether or not the two successive field images originate from a single frame image wherein the number of pixels in a vertical direction is equal to that of the field images; and a selection unit configured to select a result of the conversion by said first conversion unit or a result of the conversion by said second conversion unit in response to a result of the decision by said decision unit.
