PROBLEM TO BE SOLVED: To provide a technique for more properly controlling transfer of image data for each usage, in accordance with a situation in which the image data for a plurality of usages are transferred concurrently through the same internal bus.SOLUTION: Under a situation in which a data acquisition request signal is output from each video transfer controller 34, a PCI access controller 12 causes 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 suppress a transfer frequency of the image data for the LCD display part 22 and ensures proper transfer of the image data to each video transfer controller 34. |
