IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD

摘要

The present technique relates to an image processing apparatus and an image processing method capable of generating a color image of a display viewpoint using a color image and a depth image of a predetermined viewpoint. The viewpoint generation information generation unit generates viewpoint generation information used to generate a color image of a display viewpoint in accordance with a generation method of the color image of the display viewpoint obtained by performing warping processing using multi-viewpoint corrected color images and multi-viewpoint depth images. The multi-viewpoint image encoding unit encodes the multi-viewpoint corrected color images and the multi-viewpoint depth images, and transmits them with the viewpoint generation information. The present technique can be applied to, for example, a multi-viewpoint image processing apparatus.

1. An image processing apparatus comprising:
a receiving unit for receiving a bit stream obtained as a result of encoding of a color image of a viewpoint and a depth image of the viewpoint and viewpoint generation information used to generate a color image of a display viewpoint which is generated in accordance with a generation method of the color image of the display viewpoint obtained by performing warping processing using the color image and the depth image; a decoding unit for generating the color image and the depth image by decoding the bit stream received by the receiving unit; and a generation unit for generating the color image of the display viewpoint by performing warping processing using the color image and the depth image generated by the decoding unit and the viewpoint generation information received by the receiving unit, wherein:
the depth image is a depthwise image including a depth value representing a position of a subject in a depth direction at each pixel of the color image, or a parallax image including a parallax value representing a distance between each pixel of the color image and a pixel of a color image at a base point corresponding to the pixel,the receiving unit receives, as the viewpoint generation information, depth image identification information indicating that the depth image is the depthwise image or the parallax image,when the depth image is the depthwise image, the receiving unit receives, as the viewpoint generation information, depthwise minimum value information indicating a minimum value of world coordinate value at a position in the depth direction in the depthwise image and depthwise maximum value information indicating a maximum value of world coordinate value at a position in the depth direction in the depthwise image, andwhen the depth image is the parallax image, the receiving unit receives, as the viewpoint generation information, parallax minimum value information indicating a minimum value of the distance of world coordinate value in the parallax image and parallax maximum value information indicating a maximum value of the distance of world coordinate value in the parallax image.
