<p>PROBLEM TO BE SOLVED: To provide a semiconductor device having an eye-friendly display function.SOLUTION: When a display unit displays text, a difference between a gray level of the text and a gray level of a background of the text is reduced depending on a scrolling speed of a screen of the display unit. In other words, during fast scrolling, text visibility is lowered by bringing the gray level of the text closer to the gray level of the background. It can prevent a user from following the text with eyes at the time of fast scrolling, thereby reducing unnecessary movement of eye muscles and also reducing stimuli to the optic nerve, so that eye strain can be reduced.</p> |
