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.
