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 (121) 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 (142) finds the difference between the backlight luminance from the backlight luminance calculating section (121), and a backlight luminance from an addition section (141). A multiplication section (143) 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 (141) 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 (124) 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.
