Color Rendering for Images in Extended Dynamic Range Mode

机译:扩展动态范围模式下图像的彩色渲染

摘要

Pixel values of image content are lowered in response to setting a display mode so that the lowered pixel values of the first image content are mapped to a first color gamut. The first color gamut is defined by a nominal range space and is lower than a native color gamut of a display panel. The native color gamut is defined by the nominal range space and an extended range space that is outside of the first color gamut. One or more parameters are obtained for the image content in the display mode. A color boosting operation is performed for, from among the lowered pixel values of the image content in the nominal range space, each of first pixel values that meet one of the parameters. A color associated with each of the first pixel values is proportionally enhanced without changing a corresponding hue to utilize the extended range space.
