摘要： An apparatus for performing subpixel rendering of an RGBW display panel is provided. The apparatus receives an input gray level data to acquire a luminance value of each subpixel of a RGB pixel set including two RGB pixels adjacent to each other. The apparatus calculates a rendered luminance value of each subpixel of a display pixel set including two display pixels adjacent to each other according to the luminance values. The display pixel set of the RGBW display panel includes red, green, blue, and white subpixels. The rendered luminance value of the white subpixel of one of the display pixels is determined according to the saturation value of the corresponding RGB pixel and the luminance value of each subpixel of the corresponding RGB pixel. The apparatus acquires a gray level value of each white subpixel of the display pixel set according to the rendered luminance values.

摘要： The subject technology receives image data including a representation of a physical item. The subject technology analyzes the image data to determine an object corresponding to the physical item. The subject technology identifies a set of colors corresponding to a set of regions of the determined object. The subject technology analyzes second image data to detect a second object corresponding to a representation of a particular body part of a user. The subject technology generates augmented reality content based at least in part on the identified set of colors and the detected second object. The subject technology causes display, at a client device, the augmented reality content applied to the detected second object.

摘要： Systems and methods for displaying super saturated color. Image data for display on a display or viewing device with a potential white luminance in a standard system with a maximum luminance is processed such that colors near the white point are reduced to a limited luminance. As the chroma of the displayed color is increased, a luminance attenuation is decreased. The scaling of the reduction is operable to be a linear function, a non-linear function, or any other function.

摘要： The present invention relates to provision of a method and/or a device for transmitting and receiving a broadcast signal on the basis of color gamut resampling. The method for transmitting a broadcast signal, according to one embodiment of the present invention, comprises the steps of: resampling first color gamut-based content data into second color gamut-based content data; generating signaling information which includes color gamut resampling information indicating information on the resampling; respectively encoding the generated signaling information and the second color gamut-based content data; and transmitting the encoded content data and the encoded signaling information.

摘要： A system and method for converting raw frame data to a video file. Instead of converting all raw frame raw for each frame, embodiments create a mapping table and compare a mapping of the raw frame data for a current frame with a mapping of the raw frame data for a previous frame to determine if raw frame data changed from a previous frame to the current frame. Embodiments convert only the new raw frame data and update the mapping table with the new raw frame data, whereby the processing resources and time needed to convert raw frame data into a video file may be greatly reduced.

摘要： In an example display system, a range of colors around a region may be identified and compared to a color of the region with respect to a perception threshold. In that example, a modification of the color within the region may be determined based on the range of colors around the region and a display may be caused to present the region in a modified color based on the range of colors around the region with respect to the perception threshold.

摘要： A device for controlling a data interface of a display apparatus, can include a timing controller to encode one data transfer packet including image data according to a pixel clock to output the one data transfer packet to an interface line, and a source driver to decode the one data transfer packet to recover the image data. Also, the image data includes first image data of a first color and second image data of a second color between a first delimiter signal having a first logic value and a second delimiter signal having a second logic value, a most significant bit of the first image data is closer to the first delimiter signal than a least significant bit of the first image data, and a most significant bit of the second image data is closer to the second delimiter signal than a least significant bit of the second image.

摘要： A display apparatus and a timing controller thereof is disclosed. The timing controller detects a size of an image by using image data, generates first output image data according to the size of the image, and generates second output image data by using the first output image data. The second output image data is generated according to a saturation value of the first output image data.
