An object of the invention is to convert input RGB data to R′G′B′W data without suffering loss of gradations of the input RGB data. A display panel 12 is configured having unit pixels made up of subpixels of RGBW (red, green, blue, white). In an RGB.fwdarw.R′G′B′W conversion section 10, conversion is carried out under conditions that usage rate of W is less than 100%, and a bit width of input RGB data us larger than a bit width of R′G′B′W data after conversion. In the RGB.fwdarw.R′G′B′W conversion section 10, R1G1B1values and W values are determined so that an absolute value of a sum of values obtained by multiplying differences between respective RGB data input and respective RGB components in R′G′B′W data after conversion by a weight, becomes minimum.

An OLED display device includes an OLED display panel on which subpixels are disposed, a gamma reference voltage supply circuit supplying gamma reference voltages that are variable during driving and when sensing a threshold voltage, and a data driver supplying data voltages based on the gamma reference voltages to data lines. The data driver senses a voltage of a sensing node within each of the subpixels in sensing mode. A timing controller controls the data driver, and performs a compensation process based on the voltage sensed by the data driver.

Gaze tracking data may representing a user's gaze with respect to one or more images transmitted to a user are analyzed to determine one or more regions of interest. Compression of the one or more transmitted images is adjusted so that fewer bits are needed to transmit data for portions of an image outside the one or more regions interest than for portions of the image within the one or more regions of interest.

The present invention relates to a display device and a method for image processing thereof, in which an input image is enlarged and a part of the enlarged image is selected as an image to be displayed on the screen of a display panel, and it is possible to thereby prevent screen burn-in and to prevent a phenomenon in which pixel data is not present and thus a pixel appears black when an image is moved on the screen.

An image processing apparatus according to the present invention, includes: an input unit configured to receive a predetermined user operation for an image displayed on a display; a change unit configured to perform control of increasing a display range of the display in a case where the predetermined user operation is received by the input unit; a processing unit configured to perform gradation conversion on the image to improve gradation of a high brightness portion, based on the display range increased by the change unit; and a control unit configured to perform control of enabling the increase in the display range in accordance with the predetermined user operation in a case where the image satisfies a predetermined condition and disabling the increase in the display range in accordance with the predetermined user operation in a case where the image does not satisfy the predetermined condition.

Several embodiments of systems and methods are disclosed that create iso-perceptible image data from input image data. Such iso-perceptible image data may be created from Just-Noticeable-Difference (JND) modeling that leverages models from the Human Visual System (HVS). From a set of iso-perceptible image data set, an output image data may be selected, such that the chosen output image data has a less power and/or energy requirement to render than the input image data. Further, the output image data may have a substantially lower power and/or energy requirement than the set of iso-perceptible image data.

A method, system, apparatus, and/or device for displaying a portion of data so as to not obstruct a portion of a central visual field. The method, system, apparatus, and/or device may include a display configured to display data and a processing device coupled to the display. The processing device may be configured to determine a position of an eye of a viewer with respect to the display, define a first region of the display substantially corresponding with a peripheral vision field of the eye, define a second region of the display substantially corresponding with a central visual field of the eye, send a first portion of the data to be displayed at the first region, and send a second portion of the data to be displayed at the second output region such that a portion of the central visual field is unobstructed by the second portion of the data.

A data processing device based on a programmable logic device is described that includes at least one function circuit configured to process input data; and at least one current smoothing circuit, each corresponding to one of the at least one function circuit, and configured to smooth a current change of the programmable logic device caused when a corresponding function circuit is switched between on and off.
