Image processing method and apparatus

An image processing apparatus, comprising:

• a receiving interface configured to receive, from a camera, a first plurality of frames of raw images having a first resolution;
• and
• a processor coupled to the receiving interface and configured to:
• preprocess the first plurality of frames to obtain a first intermediate image, wherein the preprocessing comprises channel splitting and pixel rearrangement, wherein the first intermediate image comprises sub-images belonging to a plurality of channels, and wherein a sub-image of each channel comprises only one color component;
• process the first intermediate image with a first deep learning network that simultaneously performs demosaicing (DM), super-resolution (SR) reconstruction, and noise reduction, to obtain a first target image, wherein the first target image has a second resolution that is greater than the first resolution;
• and
• perform at least one of brightness enhancement or color enhancement on the first target image to obtain a second target image.
