Abstract
The present technique relates to an image processing apparatus and method that allow to suppress an increase in processing time. The image processing apparatus includes an information control unit that obtains information required for image processing for a focused pixel, using only information belonging to a slice including the focused pixel, the focused pixel being a processing target, and the information being obtained using reference information belonging to a different pixel than the focused pixel; and an image processing unit that performs the image processing using the information obtained by the information control unit. The present disclosure can be applied to image processing apparatuses.
Claims10
An image encoding apparatus, comprising:
- circuitry configured to:
- generate a decoded image based on image data associated with a picture, wherein the picture is divided into a plurality of processing units;
- classify a focused pixel of the decoded image into a class based on an amount of change in a pixel value of the focused pixel and a neighboring pixel;
- set a first flag which indicates whether to classify each processing unit of the plurality of processing units into a class, wherein
- the neighboring pixel and the focused pixel belong to a processing unit of the plurality of processing units;
- and
- execute an adaptive loop filter process based on a filter coefficient, wherein the filter coefficient is based on the classified class.
