VIDEO SIGNAL PROCESSING CIRCUIT, CONTROL METHOD OF VIDEO SIGNAL PROCESSING CIRCUIT, AND INTEGRATED CIRCUIT

摘要

An abnormal display appears when writing of pixel data in a GRAM contends with reading of pixel data of a scanning line segment including pixels corresponding to that pixel data. Pixel data corresponding to each pixel of a scanning line segment stored in a latch circuit (3) is displayed on a display screen (8). When writing of pixel data in the GRAM (2) contends with reading of pixel data corresponding to each pixel of a scanning line segment from the GRAM (2) to the latch circuit (3), a control means (4) delays reading of pixel data corresponding to each pixel of the scanning line segment and performs reading of the pixel data corresponding to each pixel of the scanning line segment again from the GRAM (2) to the latch circuit (3).
