Title:
COMPLEX DEVICE AND METHOD FOR DRIVING ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/229912
Kind Code:
A1
Abstract:
The present invention provides a display device with which it is possible to display an image at an optimum luminance without making a user aware of doing so. This method is for driving an electronic device having a display unit, an image pick-up unit, and an illuminance detection unit, the method comprising: a first step for detecting, through the image pick-up unit, that the user is visually recognizing the display unit; a second step for making a measurement of external light illuminance using the illuminance detection unit in the case when the user is visually recognizing the display unit; a third step for, according to the value of a measured external light illuminance, determining whether or not a display luminance is to be corrected; a fourth step for displaying an image at a prescribed luminance in the case when it has been determined in the third step that no correction is to be made to the display luminance; a fifth step for determining a correction value in the case when it has been determined in the third step that the display luminance is to be corrected; and a sixth step for displaying the image at a corrected luminance on the basis of the correction value determined in the fifth step.
