Abstract
Image signal processing based encoding hints for bitrate control may include an image signal processor receiving an input image signal, identifying a block of a frame based on the input image signal, generating processed image data corresponding to the block, determining a processed image indication for the block, and outputting the processed image data and the processed image indication as an encoding hint. Image signal processing based encoding hints for bitrate control may include an encoder receiving source image data for a frame, the source image data including the processed image data corresponding to the block, receiving source image indications for the frame, the source image indications including the processed image indication, determining an encoding parameter for encoding the frame based on the processed image indication, generating an encoded frame by encoding the frame using the encoding parameter, and outputting or storing the encoded frame.
