Abstract
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<α<2 is satisfied. That is, α is adjacent to 1.0. A number-of-a-plurality-of-time reading-out circuit performs a reading-out by a 3-time clock toward the input video signal. In addition, the number-of-a-plurality-of-time reading-out circuit is configured in such a manner as not to select the video signal read out by an address overtaking. A horizontal scaler interpolates the number of dots of a horizontal direction according to the number of horizontal dots of a liquid crystal panel.
