Information processing apparatus and video data luminance control method
First Claim
1. A luminance control device for controlling a luminance of video data displayed on a display panel, comprising:
- a difference value between a luminance of a current frame of the video data and a luminance of a preceding frame for a pixel; and
a luminance compensation value based on a first compensation amount and a second compensation amount, wherein the first compensation amount increases in accordance with an increase in the difference value and wherein the second compensation amount decreases in accordance with the increase in the difference value.

Abstract
An information processing apparatus capable of displaying video data on a display panel includes a unit which calculates for each pixel the difference value between the luminance of the current frame of the video data and that of the preceding frame, a selection unit which executes for each pixel a process of selecting a compensation amount having a smaller value among the first compensation amount obtained by applying the calculated difference value to the first luminance compensation characteristic in which the compensation amount increases in accordance with an increase in difference value and the second compensation amount obtained by applying the calculated difference value to the second luminance compensation characteristic in which the compensation amount decreases in accordance with the increase in difference value, and a luminance change unit which changes for each pixel the luminance of the current frame by using the compensation amount selected by the selection unit.
