Patent ID: 8368685

Claim:
An image display apparatus comprising: a signal input unit that receives a complex image signal including an image signal having a plurality of frames and a synchronization signal corresponding to the image signal, and outputs the image signal and the synchronization signal; a signal-for-display generator that converts a signal input from the signal input unit to a signal for displaying with a display element; a non-uniformity corrector that corrects non-uniformity in the display element; an apparatus state-detector that detects a state of a display apparatus including the display element, the apparatus state-detector including: an apparatus-orientation detector that detects first and second orientations in which the display apparatus is disposed, the first and second orientations being different from each other; and an apparatus operating-time detector that detects an operating time of the display apparatus in the first orientation and an operating time of the display apparatus in the second orientation, the apparatus operating-time detector detecting a time when power of the display apparatus is switched off; an arithmetic unit that calculates a correction amount based on the state of the display apparatus, the state of the display apparatus including: the orientations in which the display apparatus is disposed; a relationship among the operating time of the display apparatus in the first orientation, the operating time of the display apparatus in the second orientation, and a time taken until saturation of the display device; and the time when power of the display apparatus is switched off; and a display unit that receives a complex image signal corrected by the non-uniformity corrector, and displays the corrected complex image signal.
