Abstract
There is provided an image processing apparatus and an image processing method which are capable of reducing a processing amount of a cost calculation, the image processing apparatus including: a filter processing section configured to perform a filter process of applying an offset to a pixel of a decoded image that is decoded; and a control unit configured to control a mode used when the filter process is performed and an offset for the mode according to an encoding parameter used when an image is encoded.
Claims18
An image processing apparatus, comprising:
- a filter processing section configured to perform a filter process of applying an offset to a pixel of a decoded image that is decoded;
- and
- a control unit configured to control the offset for an encoding parameter used when an image is encoded only for a mode selected according to a parameter indicating that an orthogonal transform is not applied to the image,
- wherein the control unit is further configured to
- control a mode used when the filter process is performed, and
- control whether or not execution of the filter process is restricted according to the controlled mode,
- wherein the control unit restricts an SAO mode so as not to select edge offset as the offset, and
- wherein the filter processing section and the control unit are each implemented via at least one processor.
An image processing method, implemented via at least one processor, the method comprising:
- performing a filter process of applying an offset to a pixel of a decoded image that is decoded;
- controlling the offset for an encoding parameter used when an image is encoded through the at least one processor only for a mode selected according to a parameter indicating that an orthogonal transform is not applied to the image;
- controlling a mode used when the filter process is performed;
- controlling whether or not execution of the filter process is restricted according to the controlled mode;
- and
- restricting an SAO mode so as not to select edge offset as the offset.
