摘要： A display control apparatus may include a necessary light emission level calculation unit that calculates a necessary attention block light emission level of a back light in an attention block which satisfies a necessary luminance based on an image signal. A first neighborhood block light emission level calculation unit may calculate a light emission level of first neighborhood blocks which satisfies a deficient luminance by a light emission contribution amount to the attention block through light emission in first neighborhood blocks of the attention block which satisfies the deficient luminance by the back light in the attention block. The back light in the attention block emits the light at the largest light emission level at which the light can be emitted and back lights in the first neighborhood blocks emit the light at the first neighborhood block light emission level.

摘要： 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. An addition section (124) adds the correction value to the backlight luminance to correct the backlight luminance. The present invention can be applied to a liquid crystal display apparatus.

摘要： The present invention relates to a display control apparatus and method, and a program that are capable of appropriately controlling the luminance of light to be emitted by backlights with simple processing. On the basis of an input image signal, a peripheral-representative-value computation unit (141) computes, as a peripheral representative value, luminance that is output by backlights of a block of interest and blocks in the periphery thereof among the backlights formed from a plurality of blocks. A peripheral-contribution-amount computation unit (142) divides the peripheral representative value by light-emission efficiency based on a light-emission profile that is an output luminance distribution when the block of interest emits light so as to compute the amount of peripheral contribution by peripheral blocks to the block of interest. A light-emission level computation unit (143) computes the backlight luminance as a light-emission level by dividing a necessary amount of light emission of the block of interest by the amount of peripheral contribution. The present invention can be applied to a display device, such as a liquid-crystal display.
