An electronic-drum module for connection to one or more electronic-drum pads is provided. The module includes an electronic display; a first memory storing audio files for playback when the playback is triggered by a signal received from a pad; and one or more processors coupled to the display and the memory. The processors are configured receive an instruction to transfer a set of samples. The set of samples is associated with a priority-instruction and includes a first subset of samples and a second subset of samples. The processors are also configures to transfer the first subset of samples from a second memory to the first memory based on the priority-instruction before transferring the second subset of samples and to transfer the second subset of samples from the second memory to the first memory.

The present disclosure generally relates to a method and device of encoding a color picture having color components (Ec) comprising obtaining (11) a luminance component (L) and two chrominance components (C1, C2) from the color picture to be encoded. The method for encoding a color picture having color components comprising obtaining at least one chrominance component from the color picture to be encoded, the method further comprises: —determining a first factor based on the value of each pixel (i) of said luminance component; —obtaining at least one final chrominance component by scaling said at least one chrominance component by said first factor; and—encoding (13) said at least one final chrominance component.

A method is disclosed that comprises mapping a high-dynamic range luminance picture to a standard-dynamic range luminance picture based on a backlight value Ba.sub.c associated with the high-dynamic range luminance picture.

Disclosed is a method of RGBW compensation based on color aberrations of white subpixel and an apparatus thereof: when aberrations exist between a color coordinate point Ws of white subpixel and a standard white color coordinate point Wd under sRGB, analyzing color coordinates of every subpixel on the RGBW panel, and then dividing a triangle with vertices points Rs, Gs and Bs into three triangle regions based on Ws as the center point; based on ranges of the three triangle regions, a triangle region where Wd is located is confirmed; a first data is calibrated by performing compensating the white subpixel corresponding by the center point Ws via a predetermined normalized proportion through two subpixels corresponding to the other two points within the triangle region surrounding and locating Wd. Through the aforementioned manner, the present invention is capable of calibrating aberrations of white subpixels in order to normalize images of RGBW panels.

A display management processor receives an input image with enhanced dynamic range to be displayed on a target display which has a different dynamic range than a reference display. The input image is first transformed into a perceptually-quantized (PQ) color space, preferably the IPT-PQ color space. A color volume mapping function, which includes an adaptive tone-mapping function and an adaptive gamut mapping function, generates a mapped image. A detail-preservation step is applied to the intensity component of the mapped image to generate a final mapped image with a filtered tone-mapped intensity image. The final mapped image is then translated back to the display's preferred color space. Examples of the adaptive tone mapping and gamut mapping functions are provided.

According to an example, a system for electronic display illumination comprises a display, a sensor communicatively coupled to the display to detect a user and a user eye gaze, and a processing resource communicatively coupled to the sensor. In some examples, the processing resource may determine an active screen area and an inactive screen area of the display based on the user eye gaze; instruct a display controller to adjust a display value of the inactive screen area; and transmit active screen area data to a secondary display.
