METHOD AND DEVICE FOR ENCODING/DECODING IMAGE USING COLOR SPACE CONVERSION, AND METHOD FOR TRANSMITTING BITSTREAM - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240121391 titled 'METHOD AND DEVICE FOR ENCODING/DECODING IMAGE USING COLOR SPACE CONVERSION, AND METHOD FOR TRANSMITTING BITSTREAM
Simplified Explanation
The abstract describes an image encoding/decoding method and device that involves determining quantization parameters, transform coefficients, and residual samples of image blocks based on color space conversion.
- Determining quantization parameter based on color space conversion:
- The method involves deciding the quantization parameter of a block depending on whether color space conversion is applied to the residual sample of the block.
- Determining transform coefficient based on quantization parameter:
- The transform coefficient of the block is determined based on the quantization parameter obtained in the previous step.
- Determining residual sample using transform coefficient:
- The residual sample of the block is calculated using the transform coefficient determined in the previous step.
- Resetting the value of the residual sample based on color space conversion:
- The value of the residual sample is reset depending on whether color space conversion is applied.
