摘要：
Provided is a video signal processing circuit capable, in a scale conversion, of rendering a circuit scale small and alleviating a deterioration of a vertical resolution. A vertical scaler is provided with a function of increasing the number of scanning lines of an input video signal. An increasing rate thereof is adjacent to 1.0. In a case that the number of unit output lines is M, the number of unit input lines is N, and the increasing rate is α, a condition of 0
