Abstract: In some embodiments, color and contrast enhancement video processing may be done in one shot instead of adjusting one of color and contrast enhancement, then the other, and then going back to the first one to readjust because of the second adjustment. In some embodiments, global lightness adjustment, local contrast enhancement, and saturation enhancement may be done at the same time and in parallel. Lightness adjustment improves visibility of details for generally dark or generally light images without changing intended lighting conditions in the original shot, and is used to enhance the range of color/saturation enhancement. Local contrast enhancement done in parallel improves visual definition of objects and textures and thus local contrast and perceived sharpness.

Abstract translation: 在一些实施例中，可以一次进行颜色和对比度增强视频处理，而不是调整颜色和对比度增强之一，然后调整另一个，然后返回到第一个以由于第二调整而重新调整。 在一些实施例中，可以同时并行地进行全局亮度调整，局部对比度增强和饱和度增强。 亮度调整提高了一般黑暗或一般较轻的图像的细节的可视性，而不改变原始照片中的预期照明条件，并且用于增强色彩/饱和度增强的范围。 并行的局部对比度增强可以提高对象和纹理的视觉定义，从而提高局部对比度和感知锐度。
