Abstract: A display control device includes an insertion unit configured to insert a determination image into a static region of time-series images, the static region being a region in which a pixel value does not change over time, a processing unit configured to execute warping processing on an image into which the determination image is inserted, and a determination unit configured to determine whether or not a result of a CRC computation performed on the static region of the image after the warping processing matches first reference information.

Abstract: An image display control device with a local dimming function includes: a brightness control unit to control brightness of a plurality of light sources based on first image information representing images to be displayed on a display unit, the light sources being included in a backlight; a pixel compensation unit to generate second image information by correcting pixel values included in the first image information based on the brightness of each light source; a first statistics obtaining unit to obtain first statistical data with respect to the pixel values included in the first image information; a second statistics obtaining unit to obtain second statistical with data respect to pixel values included in the second image information; and an anomaly detection unit to detect an anomaly of the brightness control unit or the pixel compensation unit based on the difference of the second statistical data from the first statistical data.

Abstract: A control device that executes a local dimming process of a display, the control device, includes a memory; and a processor configured to execute a process including identifying a changed area in which an image is changed in a frame to be displayed on the display, analyzing, in a case where the changed area is identified, every time a frame to be displayed on the display is received, the image in the changed area in the received frame, in a corresponding one of first units for processing so that the image in the changed area is analyzed in the first units for processing over multiple frames by time division processing, and generating control information for controlling the local dimming process for a corresponding area on the display, every time an analysis result with respect to the image in the first unit of processing is output.
