Abstract:
1. A display control apparatus which is supplied with an input synchronizing signal and an input video signal, and which generates display data on the basis of the input synchronizing signal from the input video signal, and supplies the display data to display means, comprising: a video mode determination unit which determines a video mode on the basis of the input synchronizing signal; a display data generation unit which generates display data from the input video signal; a frame memory which stores the display data in correspondence to a frame; and a memory control unit which controls writing and reading of the display data with respect to the frame memory, wherein the memory control unit writes first display data generated from an input video signal of a first frame into the frame memory, reads the first display data from the frame memory in a second frame subsequent to the first frame, and supplies the first display data to the display means, and wherein, when the video mode determination unit detects a change in a cycle of the input synchronizing signal during the second frame period, in response to the detection the memory control unit repeatedly supplies the first display data to the display means during a subsequent predetermined number of frame periods.
