IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD

摘要

The present technology relates to an image processing apparatus and an image processing method capable of improving an encoding efficiency of a parallax image using information with regard to the parallax image.;A depth correction unit performs a depth weighting prediction process using a depth weighting coefficient and a depth offset based on a depth range indicating a range of a position in a depth direction, which is used when a depth value representing the position in the depth direction as a pixel value of a depth image is normalized, with the depth image as a target. A luminance correction unit generates a depth prediction image by performing a weighting prediction process using a weighting coefficient and an offset after the depth weighting prediction process is performed. A target depth image to be encoded is encoded using a depth prediction image and a depth stream is generated. The present technology can be applied to, for example, an encoding apparatus of a depth image.

1. An image processing apparatus, comprising:
a depth motion prediction unit which performs a depth weighting prediction process using a depth weighting coefficient and a depth offset based on a depth range indicating a range of a position in a depth direction, which is used when a depth value representing the position in the depth direction as a pixel value of a depth image is normalized, with the depth image as a target; a motion prediction unit which generates a depth prediction image by performing a weighting prediction process using a weighting coefficient and an offset after the depth weighting prediction process is performed by the depth motion prediction unit; and an encoding unit which generates a depth stream by encoding a target depth image to be encoded, using the depth prediction image generated by the motion prediction unit.
