Display, image processing unit, and display method for improving image quality

A liquid crystal display device includes: a light source section so configured that independently-controllable emission subsections are formed on a light-exit plane of a light-guide plate; a liquid crystal display panel modulating, based on an input picture signal, light exited from each of the emission subsections in the light source section; and a display controlling section having a partitioning-drive processing section generating, based on the input picture signal, an emission pattern signal representing a light emission pattern of the emission subsections in the light source section, and a partitioning-drive picture signal. The display controlling section performs, based on the partitioning-drive picture signal, display-drive on each pixel in the liquid crystal display panel, and performs, based on the emission pattern signal, light-emission drive through allowing one or more of first light sources and one or more of second light sources to emit concurrently so as to form the emission subsections.

Liquid crystal display device

A liquid crystal display includes: a light source unit that includes a light-guiding plate with a light-exit plane partitioned into emission subsections, and one or plural sides, and light sources; a liquid-crystal-display panel that includes pixels, and modulates light emitted from the light source unit, thereby performing image display; and a display control unit that includes a partitioning-drive processing section generating each of a light-emission pattern signal and a partitioning-drive image signal, performs light-emission driving for each light source, and performs display driving for each pixel. The partitioning-drive processing section performs a gain correction of multiplying each pixel signal in the input image signal by a predetermined gain factor that is set so that a value increases as a pixel position of the pixel signal goes away from the light source, and generates the light-emission pattern signal and the partitioning-drive image signal, by using gain-corrected pixel signal.

Liquid crystal display

A liquid crystal display includes: a light source section including emission subsections; a LCD panel including pixels each having sub-pixels for four colors of R, G, B, and Z, and modulating light from the emission subsections based on input image signals for three colors of R, G, and B; and a display control section including a partitioning-drive processing section, driving the emission subsections with an emission pattern signal, and driving the four sub-pixels with partitioning-drive image signals for the four colors. The partitioning-drive processing section generates pixel signals for the four colors through performing a first color-conversion based on the input image signals, generates the emission pattern signal from pixel signals for the three colors, primary partitioning-drive image signals for the three colors from both the input image signals and the emission pattern signal, and the partitioning-drive image signals through performing a second color-conversion on the primary partitioning-drive image signals.

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.

Image processing apparatus, image processing method, and program

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 () 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 () 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 () 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.
