Patent number: 9875695Abstract: A display device uses a control unit to analyze an image obtained by picturing a user using an image-capturing unit and detect a line of sight of the user with respect to the display region of a display unit. Further, the control unit identifies observation condition information indicating the condition of the user viewing the display region based on the detected line of sight of the user. A display control unit writes the image signal in the display region of the display unit for each frame, wherein the display control unit halts, for a predetermined frame period, writing of the image signal in a controlled region when the identified observation condition information meets a predetermined requirement, the controlled region being at least a part of the display region.Type: GrantFiled: February 24, 2014Date of Patent: January 23, 2018Assignee: SHARP KABUSHIKI KAISHAInventor: Hikaru Kuki

Publication number: 20160035289Abstract: The phenomenon of the hue of an image displayed in a liquid crystal display changing depending on whether or not CABC is employed is reduced. An image processing device sets a predetermined first brightness as the backlight brightness if CABC is not to be performed, and if CABC is to be performed, sets, for each frame of an image signal displayed on the liquid crystal panel, a second luminance determined according to the gradation of the pixels in the frame. If CABC is to be performed, the image processing device corrects the gradation values of the primary colors of the pixels in each frame of the image signal according to the second luminance set for that frame and on the basis of the display characteristics of the liquid crystal panel.Type: ApplicationFiled: February 26, 2014Publication date: February 4, 2016Applicant: SHARP KABUSHIKI KAISHAInventors: Ken INADA, Hikaru KUKI, Asahi YAMATO
