Method for driving information processing device and program and information processing device

摘要

In order to reduce the frequency of rewriting pixels, gray scales of image signals input to a plurality of pixels provided in a display portion are checked before displaying each image. Specifically, in the case where image signals having medium gray scale levels are input to many of the plurality of pixels, display is performed by normal driving (for example, driving in which rewriting pixels is performed at a frequency higher than or equal to 60 times per second); otherwise, display is performed by driving with a small number of frequencies of rewriting pixels (for example, driving in which rewriting pixels is performed at a frequency lower than or equal to once per second). With this method, an information processing device which can reduce users' eye strain and perform eye-friendly display can be provided.

主权项

1. A method for driving an information processing device in which image signals are input to first to A-th pixels (A is a natural number greater than or equal to 2), comprising the steps of:
counting pixels to which an image signal having a gray scale level within a set range are input in the first to B-th pixels (B is a natural number smaller than A) of a next image before displaying the next image; rewriting the first to A-th pixels at a first refresh rate in the case where the number of the counted pixels (CTR) is greater than a set pixel number, and the next image refreshed at the first refresh rate is displayed; and rewriting the first to A-th pixels at a second refresh rate which is lower than the first refresh rate to reduce flicker in the case where the sum of the number of the counted pixels (CTR) and a value (A−B) is smaller than the set pixel number, and the next image refreshed at the second refresh rate is displayed, wherein the counting pixels is stopped at the time point when the number of the counted pixels (CTR) is greater than the set pixel number, and the first to A-th pixels are rewritten at the first refresh rate.
