Abstract: Systems and methods for improving operation of an electronic device, which includes an image data processing pipeline that processes input image data. In the processing pipeline, a first processing block generates first processed image data by performing a first function on the input image data; another one or more processing blocks, which includes a second processing block coupled to a first output of the first processing block, generates second processed image data by performing a second function on the first processed image data when received from the first processing block; and a third processing block coupled to the first output and a second output of the other one or more processing blocks performs a third function on the first processed image data when received from the first processing block and performs the third function on the second processed image data when received from the other one or more processing blocks.

Abstract: Systems and methods for improving operational flexibility of a display pipeline coupled to a display panel that facilitates display of an image by controlling luminance of a display pixel based on display image data. The display pipeline includes a format convert block that receives source image data that indicates target luminance of the display pixel using a source format; determines a color scaling factor associated with a color component in the source image data based on the source format; and generates internal image data that indicates target luminance of the display pixel using an internal format based on application of the color scaling factor to the source image data. Additionally, the display pipeline includes an image data processing block coupled to the format convert block, which processes the internal image data before the display image data is generated to facilitate improving perceived image quality when the image is displayed.
