Abstract: The present disclosure relates to an image processing apparatus and an image processing method that make it possible to generate a texture image of high picture quality at a predetermined viewpoint using an omnidirectional image. A plurality of real cameras image a plurality of reference images at a plurality of viewpoint positions in a plurality of sight line directions. A great weight is applied to a reference image in a sight line direction close to a virtual viewpoint specified in response to a movement of a head mounted display and having a virtual viewpoint position and a sight line direction to generate a virtual viewpoint image by weighted averaging, and the virtual viewpoint image is displayed on the head mounted display. The present disclosure can be applied, for example, to a home server or the like that generates a display image of a predetermined viewpoint from an omnidirectional image.

Abstract: 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.
