Abstract
The present invention provides an image encoding method and an image decoding method. The image decoding method, according to the present invention, comprises the steps of: decoding information associated with a clipping range of a current block; and performing sample adaptive offset (SAO) filtering on the basis of the information associated with the clipping range, wherein the information associated with the clipping range may include information on the maximum and minimum values of a pixel value included in the current block.
Claims15
An image decoding method, comprising:
- decoding information associated with a clipping range of a current block;
- and
- performing sample adaptive offset (SAO) filtering on the basis of the information associated with the clipping range,
- wherein the information associated with the clipping range includes information on a maximum value and a minimum value of a pixel value included in the current block.
An image encoding method, comprising:
- determining a clipping range of a current block;
- performing sample adaptive offset (SAO) filtering on the basis of the clipping range;
- and
- encoding information associated with the clipping range,
- wherein the information associated with the clipping range includes information on a maximum value and a minimum value of a pixel value included in the current block.
An image decoding device, comprising:
- a decoding unit decoding information associated with a clipping range of a current block;
- and
