Image coding method, image coding apparatus, image decoding method, image decoding apparatus, and image coding and decoding apparatus
View Patent ↗The image coding method for coding an input image includes: converting, into a bin string, an offset value used in an offset process to be applied to a pixel value of a reconstructed image corresponding to the input image; and performing bypass arithmetic coding on the bin string using a fixed probability.
1. An image decoding method for decoding a coded image, the method comprising:
performing, using a processor, bypass arithmetic decoding on a bin string using a fixed probability;
converting the decoded bin string into a sample adaptive offset value; and
applying, in a sample adaptive offset process, the sample adaptive offset value to a pixel value of a reconstructed image corresponding to the coded image.
2. An image decoding apparatus that decodes a coded image, the apparatus comprising
a control circuit and storage electrically connected to the control circuit,
wherein the control circuit executes:
performing bypass arithmetic decoding on a bin string using a fixed probability;
converting the decoded bin string into a sample adaptive offset value; and
adding, in a sample adaptive offset process, the sample adaptive offset value to a pixel value of a reconstructed image corresponding to the coded image.
