In one embodiment, a method is provided. The method includes comparing a first hue of a displayed test pattern with a second hue of a generated test pattern to determine one or more differences in hue. The displayed test pattern is displayed on a display of a media viewing device, and the media viewing device receives and displays digital content. The displayed test pattern includes a first plurality of steps, and a first step of the first plurality of steps includes the first hue. The generated test pattern includes a second plurality of steps, and each step of the second plurality of steps includes the second hue. The one or more differences in hue are utilized to determine a quality of the digital content displayed on the media viewing device.

A display device, includes: a first processor configured to increase or decrease values of color components representing three colors and included in a first video signal, in accordance with values corresponding to the values of the color components representing three colors; a second processor configured to convert a second video signal into a third video signal, the second video signal including the color components representing three colors and having the values increased or decreased by the first processor, and the third video signal including color components representing four colors; and a display configured to display the third video signal including the color components representing four colors.

A burn-in compensation method and a computing device configured for burn-in compensation is disclosed. The burn-in compensation can minimize or eliminate a burn-in of an OLED display having areas with different pixel densities. Each area of the OLED display may be divided into zones that include one or more pixels and a burn-in factor may be computed for the zones. A limiting burn-in factor may be determined from a limiting zone that exhibits the highest burn-in. Other zones with burn-in factors that area significantly different from the limiting burn-in factor can be adjusted so that the pixels in the adjusted zones can be driven to radiate similar light at a power similar to the liming zone. The burn-in compensation may be performed for each area and a transition region may be created between areas to minimize light artifacts after burn-in compensation.

A display device according to an embodiment of the present application comprises a storage configured to store gamut mapping data, a controller configured to, when an image signal is input, convert the input image signal into an output signal based on the gamut mapping data, and a display configured to display an image based on the output signal, wherein the controller changes the gamut mapping data according to the input image signal.

Disclosed is a display device which includes a display panel that includes a plurality of pixels and includes a display area displaying an image, a panel controller that receives an external input signal from an external source and generates a control signal for dividing the display area into a first area and a second area which is disposed adjacent to the first area based on the external input signal, and an instrument module that stretches the first area and the second area of the display panel in response to the control signal. The number of the pixels per unit area in the first area is different from the number of the pixels per unit area in the second area.

An embodiment of the present disclosure provides a method for processing an image. The method comprise: determining weights corresponding to candidate colors for a target color based on an original color of a pixel in the image; selecting a target color of the pixel from the candidate colors based on the weights; and converting the original color of the pixel into the target color to obtain a target image. According to the embodiment of the present disclosure, by determining the weights of the candidate colors, the image can be converted into the target image comprising only the candidate colors, thereby using a limited number of candidate colors to represent the target image.
