Abstract:
1. Picture angle detection equipment for detecting the angle of a picture related to a pixel to be interpolated on the basis of an inputted video signal, comprising: a binary pattern generation device that binarizes said inputted video signal in a predetermined detection region including a plurality of scanning lines and said pixel to be interpolated, to generate a binary pattern; a reference pattern generation device that generates a binary picture having a plurality of directions as a plurality of reference patterns; a comparison device that compares the binary pattern generated by said binary pattern generation device with each of the plurality of reference patterns generated by said reference pattern generation device, and that detects the angle of the picture related to said pixel to be interpolated on the basis of the results of the comparison; and a continuity detection device that detects whether or not the angle of the picture detected by said comparison device with respect to said pixel to be interpolated has continuity from the angle of a picture detected on an upper or lower interpolation scanning line, to output the angle of the picture detected by said comparison device as an angle signal when there is continuity, while not outputting the angle of the picture detected by said comparison device when there is no continuity.
