Patent ID: 7202850

Claim:
An image display control apparatus that controls light transmittance of liquid crystals of a liquid crystal display screen for displaying an image based on an inputted image signal and controls, according to the light transmittance of the liquid crystals, an amount of light emitted by a backlight unit for illuminating a back of the liquid crystal display screen based on the image signal, the image display control apparatus comprising: an image state detection unit operable to detect a state of the image based on the image signal; an image signal transformation unit operable to transform the image signal by performing predetermined signal processing on said image signal based on the state of the image detected by the image state detection unit, and control the light transmittance of the liquid crystals based on the transformed image signal; and a resource control unit operable to: assign an arithmetic operation resource, which performs an arithmetic operation, to the image state detection unit, instead of to the image signal transformation unit, at a predetermined time when the image state detection unit is to use the arithmetic operation resource; and assign the arithmetic operation resource to the image signal transformation unit, instead of to the image state detection unit, at a predetermined time when the image signal transformation unit is to use the arithmetic operation resource, which is different than the predetermined time when the image state detection unit is to use the arithmetic operation resource, wherein the image state detection unit detects the state of the image using the assigned arithmetic operation resource, and the image signal transformation unit transforms the image signal using the assigned arithmetic operation resource.
