摘要： 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.

摘要： A control system for a variable-cylinder internal combustion engine, which is capable of attaining excellent fuel economy by executing a partial-cylinder operation mode as long as possible, while suppressing vibration and noise during the partial-cylinder operation mode. A control system switches the operation mode of a variable-cylinder internal combustion engine between an all-cylinder operation mode in which all of a plurality of cylinders (#1 to #3, and #4 to #6) are put in operation, and a partial-cylinder operation mode in which some (#1 to #3) of the plurality of cylinders are deactivated. During the partial-cylinder operation mode, the control system 1 calculates a degree-of-continuation parameter SDTQCSNH indicative of a degree of continuation of a state where detected load TQECMDF on the engine is within a predetermined range of load between a first reference value TQCSNH and a second reference value TQCSEH smaller than the first reference value (steps 10 to 13), and determines whether or not the operation mode should be switched to the all-cylinder operation mode, based on the degree-of-continuation parameter SDTQCSNH (step 14).

摘要： An optical state modulation unit is provided to apply an optical intensity modulation in temporal domain on a display image generated from an inputted image signal for different gray scale values such that the optical intensity modulation performed at least one of the gray scale values of the display image falls into a region at which the flicker is perceptible to human vision when a recorded image obtained by image-capturing the display image is viewed, while remaining imperceptible when the display image is directly viewed. The optical state modulation unit provides the optical intensity modulation such that the average optical intensity of the display image based on the image signal with the optical intensity modulation is the same as that of the display image generated from the image signal without the optical intensity modulation at each gray scale value.
