Patent ID: 8780145

Claim:
An image display apparatus comprising: a panel that includes a plurality of picture elements that change transmittance of light according to picture level; a detection unit that detects, in one-image portions of said panel, picture levels for each of said plurality of picture elements from picture signals that indicate said picture level of each picture element; and a processor that adjusts the transmittance of light of said plurality of picture elements such that the image produced by said picture signals is brighter when a value corresponding to brightness that is based on the picture levels of one-image portions that were detected by said detection unit is greater than a predetermined threshold value, wherein said detection unit calculates an average picture level as said value that corresponds to brightness from said picture levels of one-image portions, and wherein said processor, when said average picture level is greater than said predetermined threshold value, increases said transmittance of light of said plurality of picture elements in proportion to the average picture level.
