  • Patent number: 8248361
    Abstract: The present invention relates to a display control apparatus and method, and a program which make it possible to prevent deterioration in image quality due to insufficient luminance of light from a backlight. 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 a display image. A moving image determining section (122) determines whether or not the display image is a moving image on the basis of the image signal. A correction value calculating section (123) increases the last correction value by a predetermined value to obtain a new correction value when the display image is a moving image, and decreases the last correction value by a predetermined value to obtain a new correction value when the display image is a still image.
