Abstract

An information processing device including a display unit and an input unit is driven by a first step of inputting an input signal from the input unit, a second step of starting to move an image displayed on the display unit, a third step of lowering luminance of the image, a fourth step of checking whether the image reaches a position of predetermined coordinates, a fifth step of increasing the luminance of the image in the case where the image reaches the position of the predetermined coordinates, and a sixth step of stopping moving the image so as to perform eye-friendly display with the display unit.
