Image processing method and related device

An image processing method, wherein the method comprises:

• determining, based on an obtained first high dynamic range (HDR) image, first base-layer data and first enhancement-layer data that correspond to the first HDR image, and first metadata, wherein the first metadata is used in conversion of target data, and the target data is the first base-layer data and/or the first enhancement-layer data, wherein the conversion comprises one or more of:
• color space conversion, color gamut conversion, or color compensation;
• and
• encoding the first base-layer data, the first enhancement-layer data, and the first metadata, to obtain a bitstream.

A computer device, comprising a processor, wherein the processor is coupled to a memory storing instructions and/or program codes, and is configured to read and execute the instructions and/or program codes stored in the memory, to cause the computer device to perform operations comprising:

• obtaining first base-layer data, first enhancement-layer data, and first metadata, wherein the first base-layer data is base-layer data corresponding to a first high dynamic range (HDR) image, and the first enhancement-layer data is enhancement-layer data corresponding to the first HDR image;
• performing conversion on target data according to the first metadata to obtain target conversion data, wherein the target data is the first base-layer data and/or the first enhancement-layer data, wherein the conversion comprises one or more of:
• color space conversion, color gamut conversion, or color compensation;
• and
• determining a second HDR image based on the target conversion data.

A non-transitory computer-readable storage medium configured to store a bitstream, wherein the bitstream is determined based on a method comprising:

• determining, based on an obtained first high dynamic range (HDR) image, first base-layer data and first enhancement-layer data that correspond to the first HDR image, and first metadata, wherein the first metadata is used in conversion of target data, and the target data is the first base-layer data and/or the first enhancement-layer data, wherein the conversion comprises one or more of:
• color space conversion, color gamut conversion, or color compensation;
• and
• encoding the first base-layer data, the first enhancement-layer data, and the first metadata, to obtain the bitstream.
