By setting the color temperatures of displays included in a display system to a desired value, the life of the displays and display system is extended. A method for setting color temperatures of multiple displays (10) included in a display system (100) includes acquiring outputable maximum luminances of the displays (10) at each of multiple color temperatures, the outputable maximum luminances being maximum luminances that the displays (10) are able to output at each of the color temperatures, comparing the outputable maximum luminances of the displays (10) at the same color temperature and determining the lowest maximum luminance value for each of the color temperatures, the lowest maximum luminance value being the lowest of the outputable maximum luminances, setting, as a common set color temperature, a color temperature corresponding to the highest of the lowest maximum luminance values identified for each of the color temperatures, and setting color temperatures of at least two of the displays (10) to the common set color temperature.

Provided is a liquid crystal display device that can further reduce flicker. The liquid crystal display device includes a control unit that controls the luminance of a backlight using PWM dimming. The backlight includes n (n4) number of backlight blocks that are turned on at different timings, and the n number of backlight blocks are turned on in an order different from the order in which the backlight blocks are physically arranged.

Provided is a photosensor device that even when the width and thickness of a bezel are reduced, can cause a sensor unit to smoothly exit and enter the bezel. Using drive means, a photosensor device (1) causes a sensor unit (3) to perform multiple rotation operations (4a, 4b, 4c, 4d). Thus, the sensor unit (3) is allowed to approach a display screen (101a) of an image display panel (101) for a measurement and to be stored in a bezel (20) after the measurement.


A technique to remove fog from an image more appropriately has been called for. An image processing system is provided, including: a luminance evaluation value deriving unit that derives a luminance evaluation value of an at least partial region of an image; a saturation evaluation value deriving unit that derives a saturation evaluation value of the at least partial region of the image; a contrast evaluation value deriving unit that derives a contrast evaluation value of the at least partial region of the image; and a haze depth estimating unit that derives a haze depth estimate value of the image based on the luminance evaluation value, the saturation evaluation value, and the contrast evaluation value.


A technique to remove fog from an image more appropriately has been called for. An image processing system is provided, including: a high saturation pixel extracting unit that extracts, from one frame among a plurality of frames included in a moving image, a high saturation pixel having a saturation higher than a predetermined threshold; a high saturation pixel rate deriving unit that derives a high saturation pixel rate indicative of a percentage of the high saturation pixels in the one frame; and a scene change judging unit that judges whether or not a scene change is included in the moving image based on different criteria depending on whether or not the high saturation pixel rate in the one frame is higher than a predetermined threshold.

To allow fog removal even in a densely foggy image. A fog density calculating unit 11 calculates the fog density of an input image given, by using a separated illumination light component. A reflectance component fog removing unit 13 performs fog removal on a reflectance component calculated by a reflectance calculating unit. An illumination light component fog removing unit 14 performs fog removal on the separated illumination light component. Here, the degree of fog removal by the reflectance component fog removing unit 13 is higher than the degree of fog removal by the illumination light component fog removing unit 14. Thereby, the degree of fog removal of the reflectance component can be raised without significantly raising the level of fog removal of the illumination light component.
