Publication number: 20170019685Abstract: In a sample adaptive offset (SAO), the coding efficiency is improved by selecting an optimum mode among a plurality of modes based on a technique called a band offset and an edge offset. However, a processing amount of the SAO tends to increase when an optimum mode and an offset value are set, and this may result in an increase in a circuit size or power consumption. In this regard, the present disclosure proposes to enable reducing a processing amount of a cost calculation of the sample adaptive offset. According to the present disclosure, there is provided an image processing apparatus, including: a control unit configured to set an offset value to be applied to a pixel of an image, from among candidates of the offset value restricted according to a bit depth of the image; and a filter processing section configured to perform a filter process of applying the offset value set by the control unit to the pixel of the image.Type: ApplicationFiled: March 18, 2015Publication date: January 19, 2017Applicant: SONY CORPORATIONInventors: Yoshitaka MORIGAMI, Takefumi NAGUMO, Junichi TANAKA, Hironari SAKURAI
