SEMICONDUCTOR DEVICE, METHOD FOR DRIVING SEMICONDUCTOR DEVICE, AND PROGRAM
First Claim
1. A semiconductor device comprising:
- a pixel portion configured to display image information in a first mode and a second mode;
an input portion configured to sense an input by a user; and
a light supply portion configured to emit light to the pixel portion with first luminance in the first mode and with second luminance in the second mode,wherein the first mode is selected when the input has higher speed than a predetermined value and the second mode is selected when the input has lower speed than the predetermined value, andwherein the first luminance is lower than the second luminance.

Abstract
To reduce eye fatigue of a user and perform eye-friendly display. An information processing device provided with a display portion and an input portion has a first mode in which the contrast or the brightness of a displayed image is adjusted and a second mode in which the contrast or the brightness of a displayed image is set to the initial set value. In the case where an image is displayed and a signal such as a scroll instruction is input to the input portion, the contrast or the brightness of the displayed image is adjusted depending on the content of the scroll instruction; thus, the information processing device can perform eye-friendly display.

8. A semiconductor device comprising:
-
a pixel portion configured to display image information in a first mode and a second mode; a light supply portion configured to emit light to the pixel portion with first luminance in the first mode and with second luminance in the second mode; and an arithmetic device configured to supply a control signal to the light supply portion and an image signal for displaying the image information in the pixel portion, wherein the first mode is selected depending on the control signal when an area of a dark portion in the image information is larger than a predetermined value and the second mode is selected depending on the control signal when the area of the dark portion in the image information is smaller than the predetermined value, and wherein the first luminance is lower than the second luminance. - View Dependent Claims (9, 10, 11, 12)
