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

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);
• rewriting the first to A-th pixels at a first refresh rate in the case where the number of the counted pixels is greater than or equal to a set pixel number;
• and
• rewriting the first to A-th pixels at a second refresh rate which is lower than a first refresh rate in the case where the sum of the number of the counted pixels and a value (A−B) is smaller than the set pixel number.

A method for driving an information processing device in which image signals are input to a plurality of pixels, comprising the steps of:

• detecting the proportion of pixels to which image signal having a gray scale level within a set range are input in the plurality of pixels;
• rewriting the plurality of pixels at a first refresh rate in the case where the detected proportion is greater than or equal to a set proportion;
• and
• rewriting the plurality of pixels at a second refresh rate which is lower than a first refresh rate in the case where the detected proportion is smaller than the set proportion.
