<P>PROBLEM TO BE SOLVED: To more appropriately display an image by simple processing. <P>SOLUTION: In an LCD (Liquid Crystal Display) controller in which read-out timing of data of one pixel from a V(Video RAM) RAM is earlier than write-in timing of data of one pixel to the VRAM, a default value Ddef is usually set to the readout timing (S320), and when difference (Ac1-Ac2) between address counter Ac1 for write-in and address counter Ac2 for read-out becomes the prescribed value Aref or less, the read-out timing is set to a set value Dlow same as the write-in timing (S330). Thereby, the occurrence of overtaking phenomenon in which read-out of data overtakes write-in of data can be evaded, image can be more appropriately displayed for a liquid crystal display. <P>COPYRIGHT: (C)2011,JPO&INPIT |
