摘要： A display position information acquisition section of an image display device outputs display position identification data for identifying a display position on the screen. An LED output value calculation section divides an input image into a plurality of areas and obtains LED data which is data for emission luminances of LEDs in the areas. At this time, emission luminances of LEDs in a non-display area are set to 0 on the basis of the display position identification data. A display luminance calculation section obtains display luminances of the areas based upon the emission luminances. A partial display correction filter generation section generates a partial display correction filter having correction data for each pixel stored therein, based upon the display position identification data. An LCD data calculation section obtains liquid crystal data based upon the input image, the display luminances, and the correction data.

摘要： A luminance gradient calculating unit of a stereoscopic image generating device calculates luminance gradient indicating amount in change of luminance between a pixel of interest and an adjacent pixel, a right eye image generating unit corrects luminance of the pixel with that correction amount of the same sign as the luminance gradient such that the greater the absolute value of luminance gradient or the smaller the distance is the greater the luminance is. The left eye image generating unit performs correction of the luminance of the pixel with a correction amount of the opposite sign of the luminance gradient. This enables stereoscopy due to difference generated in luminance distribution between the left eye image and right eye image, and also the position of pixel is not changed and thus can be kept from appearing in double or not readily appearing in double.

摘要： When first and second region-processing sections (510, 520) calculate in parallel backlight luminances required for an input image halved by a regional image division section (505) included in an area-active drive processing section (5) of a liquid crystal display device, LED data (Db1, Db2) are exchanged for each other, allowing reference to backlight luminances not calculated for one region but calculated for the other region. As a result, when an area is illuminated by surrounding backlight sources, the actual display luminance can be calculated correctly. Thus, pixel display can be provided with correct display tones across the entire screen, thereby preventing a reduction in display quality.

摘要： In a three-dimensional image generating apparatus, a luminance gradient calculating portion calculates a luminance gradient, which indicates the amount of change in luminance between a pixel of interest and a pixel adjacent thereto, a right-eye image generating portion corrects a pixel luminance in a correction amount having the same sign as the luminance gradient, and a left-eye image generating portion corrects a pixel luminance in a correction amount having the opposite sign to the luminance gradient. As a result, there is a difference in luminance distribution between left-eye and right-eye images, so that stereoscopic viewing is made possible without calculating depth information, and there is no change in pixel positions, so that the images do not appear doubled or they are resistant to appearing doubled.

摘要： An object of at least one embodiment of the present invention is to provide a liquid crystal display device and a driving method thereof, in which a contour of an image is clearly recognized during movie display even in a case where a backlight is turned on and off so as to change intervals at which the backlight turns on. In at least one embodiment, the liquid crystal display device includes a liquid crystal panel and the backlight that irradiates the liquid crystal panel with light, one frame period including a turn-on period during which the backlight turns on and a turn-off period during which the backlight turns off, luminance being changed by changing turn-on intervals of the backlight, the turn-on intervals of the backlight being changed by changing lengths of the turn-on period and the turn-off period. The liquid crystal display device further includes an OS process circuit for controlling a drive voltage to be applied to the liquid crystal panel by setting an amplitude of the drive voltage to be applied to the liquid crystal panel during a gray scale transition. The OS process circuit sets the amplitude of the drive voltage to be applied to the liquid crystal panel during the gray scale transition so as to be greater as the turn-on period of the backlight is longer under a condition where gray scales that have not been subjected to a gray scale transition is equal to gray scales that have been subjected to the gray scale transition in a case where the turn-on period of the backlight varies.
