To further surely prevent burning, even when any image data is selected for slide show display.
A control section 8 calculates a value A (a pixel value) of each color of each area of the plurality of image data selected by a user. The control section 8 accumulates the value A (the pixel value) of the displayed image data for each divided area, every time the image data is switched at slide show display time. When an accumulated value of the value A (the pixel value) is a predetermined threshold or more, in any area of the divided area, the plurality of image data used for slide show display is replaced with the other image data so that the image data including the accumulation value of the value A (the pixel value) in the area is suppressed or decreased may be displayed next.
