Abstract: A display control device according to the present invention includes an illuminance value obtaining unit for obtaining an illuminance value of a display screen, a display image controlling unit for controlling a display image on the display screen on the basis of the illuminance value obtained, a distance determining unit for determining whether a distance between an object present around the display screen and the display screen is equal to or shorter than a threshold, and an illuminance value obtaining method determining unit for causing the illuminance value obtaining unit to apply a first obtaining method of the illuminance value when it is determined that the distance is not equal to or shorter than the threshold and causing the illuminance value obtaining unit to apply a second obtaining method of the illuminance value when it is determined that the distance is equal to or shorter than the threshold.

Abstract: The followings are included: a capacitive sensor (101) having a detection region that extends in a parallel direction with respect to an operation surface (301) for accepting a 3D gesture by an operation body, the detection region being in an area close to the operation surface (301); and an infrared sensor (102) having a detection region having directivity in a direction perpendicular to the operation surface (301). The capacitive sensor (101) and the infrared sensor (102) are arranged such that a 3D gesture by the operation body can be detected in the parallel direction and the perpendicular direction with respect to the operation surface (301).

Abstract: Provided is a display control device and the like which reduces an uncomfortable feeling when a user visually recognizes a display screen by determining an obtaining method of an illuminance value of the display screen depending on presence or absence of a proximity object with respect to the display screen and controlling a display image on the display screen on the basis of the obtained illuminance value.

Abstract: The present invention causes noise in a low-luminance portion to become less prominent when a backlight is divided into a plurality of regions and the luminance of the backlight is controlled in accordance with a video signal corresponding to each of the regions. An area active control portion (2) divides a video signal into a plurality of regions and outputs a first feature amount for every region. An LED control portion (3) determines a first luminance for each of the divided regions of an LED backlight (5) in accordance with the first feature amount of every region. Within a range where the total value of an LED drive current is no greater than a predetermined allowable current value, a magnification constant is uniformly multiplied by the first luminance to determine a second luminance.

Abstract: The present invention effectively suppresses not only occurrences of halos but also degradation of the black level. This image display device has a liquid crystal panel (17) that displays images according to an image signal and a backlight (14) in which LEDs are used and controls the light emission brightness of the LEDs for each division region, which is obtained by dividing the backlight (14) into a plurality of regions, on the basis of a prescribed relation between a gradation value for an image region corresponding to each division region and the LED light emission brightness.

Abstract: Light leakage and black float are reduced in dark ambient while a perception of high contrast is achieved when a backlight is divided into a plurality of areas and backlight brightness is controlled depending on a video signal corresponding to each area. An area active control portion (2) divides a video signal into a plurality of areas and outputs a first feature value for each area. An LED control portion (3) acquires a first brightness for each divided area of an LED backlight (5) depending on the first feature value of each area, and acquires a second brightness for each area that is acquired by uniformly multiplying a specific multiplying factor acquired depending on the lighting ratio of the LED backlight (5) with respect to the first brightness within a range where a total value of the LED driving current does not exceed a predetermined permissible current value.

Abstract: In general, when a user views an image displayed on a display apparatus, visual environments, such as ambient brightness, a distance from the user to the display apparatus and so on, may disadvantageously cause the image displayed on the display apparatus to become difficult to view. Moreover, it is complicated and troublesome for the user to enter information of ambient light amount and others when setting a picture quality. An image display apparatus holds both question constituent information related to visual environments and choice information serving as answers to questions constituted by the question constituent information, and further holds a plurality of picture quality control rules suitable for visual environments assumed in accordance with the choice information serving as the answers.
