PROBLEM TO BE SOLVED: To provide a display device capable of lowering the possibility of slide show completion on its midway for shortage of a charging power, a display control method, and a display control program.SOLUTION: The display device can carry out a slide show displaying a plurality of images specified by a user on a display while successively changing over the images according to a display condition by a charging power charged in a battery. The display device acquires a total expected consumption electric energy required for displaying all images by the slide show while referring to consumption-power information (S3). A charging electric energy charged in the battery is detected (S4). The display device decides whether the charging electric energy is a total expected consumption electric energy or more (S5). When the charging electric energy is smaller than the total expected consumption electric energy (S5: NO), the display device changes the display condition so as to lower a consumption electric energy consumed by the slide show (S6). |
