A display pipe may include a video pipe outputting pixels of a video stream in a first color space, e.g. YCbCr color space. The display pipe may also include a first color space converter to convert the output pixels to a second color space, e.g. to RGB color space, producing a conversion output in which some of the converted output pixels have values that are invalid pixel values in the second color space. The display pipe may also include a blend unit that performs blending operations in the second color space on the converted output pixels to produce a blended conversion output that includes blended pixels in the second color space. A second color space converter in the display pipe may convert the blended pixels from the second color space to the first color space, and correctly display the converted blended pixels on a display screen. |
