Patent ID: 8299993

Claim:
An image display apparatus comprising: an image display device including a drive control unit capable of changing a scanning direction; an image processing device for performing image processing on an inputted image signal to output the processed image signal to said image display device, said image processing device including a sample-hold circuit which changes a sample hold timing of each of a plurality of color signals in accordance with a change in the scanning direction of said image display device and an array order of RGB color pixels equipped by said image display device; and a setting device for setting an image processing for said image processing device to change at least one of a brightness level and a contrast level of the image signal from said image processing device in accordance with the scanning direction of said image display device, before a scanning process for the image signal is performed by said image display device and said image processing device, wherein said setting device sets the image processing to change at least one of the brightness level and the contrast level to decrease a difference between a first output signal characteristic of said sample-hold circuit caused by a first sample hold timing of each of the color signals for a first scanning direction according to the array order of the RGB color pixels and a second output signal characteristic of said sample-hold circuit caused by a second sample hold timing of each of the color signals for a second scanning direction according to the array order of the RGB color pixels.
