Abstract
PURPOSE: To simplify a circuit by writing image data to an image memory with a signal dividing an image signal period and reading the data out with a signal dividing one cycle of a composite image signal which consists of an image signal period and a non-image-signal period. CONSTITUTION: The image data are written to either of two memories L1 and L2 in a line memory 103, and image data read out of the line memory 103 are supplied to a column-side driving circuit 105 through a switch 104. To write the image signal data to the image memory 103, the image signal period Tv is divided into N periods and sampling is performed at intervals of a time Tv/N. To read the image signal data out, image signal data of one image signal period Tv are read out of the image memory 103 at intervals of a time Tc/M in one cycle Tc of the composite image signal. Here, M>=N (M and N are positive integers) and Tc/M>Tv/N. Consequently, the circuit can be simplified.
