<P>PROBLEM TO BE SOLVED: To provide a technique for more properly controlling transfer of image data for plural usages through the same internal bus, in accordance with the situation in which the image data for plural usages are transferred concurrently. <P>SOLUTION: Under a situation in which a data acquisition request signal is output from each video transfer controller 34, a PCI access controller 12 elongates the periods of a clock LcdClk, a horizontal synchronization signal LcdHsync, and a vertical synchronization signal LcdVsync which an LCD controller 21 supplies, for operation, to an LCD display part 22 to be longer than those in usual times. This saves the transfer frequency of the image data for the LCD display part 22 and ensures the proper transfer of the image data to each video transfer controller 34. <P>COPYRIGHT: (C)2012,JPO&INPIT |
