Abstract
The invention provides an image display apparatus that includes: a frame memory into which inputted image data is stored; a statistical computation section that performs statistical computation on a gradation value of each pixel on the basis of the image data for each frame image; a correction section that corrects the image data stored in the frame memory on a frame-by-frame basis by means of a statistical computation result calculated at the statistical computation section; an image display section that performs image display by means of the image data corrected at the correction section; a light source control section that calculates a control amount applied to the amount of light emitted from a light source on the basis of the corrected image data and then controls the amount of light emitted from the light source in accordance with the control amount; and a still picture judgment section that makes a judgment as to whether the frame image constitutes a still picture or not. In such a configuration of the image display apparatus according to an aspect of the invention, the statistical computation section suspends the statistical computation till the frame image is updated if the still picture judgment section judges that the frame image constitutes a still picture.
