Abstract
The present invention relates to a display control apparatus and method, and a program which make it possible to suppress deterioration in the image quality of an image. A backlight luminance calculating section () finds the backlight luminance of light to be radiated by a backlight, on the basis of the image signal of an image. A subtraction section () finds the difference between the backlight luminance from the backlight luminance calculating section (), and a backlight luminance from an addition section (). A multiplication section () multiplies the found difference by a cyclic coefficient indicating the degree of contribution of the difference to correction of the backlight luminance, obtaining a correction value. The addition section () adds the correction value to the backlight luminance to correct the backlight luminance. Also, from the image signal and the backlight luminance, a division section () calculates the transmittance of light in a liquid crystal panel that displays an image by transmitting light from the backlight. The present invention can be applied to a liquid crystal display apparatus.
