Abstract

In a depth image compressing section of an image processing device, a depth image operation section generates a depth image by operation using photographed stereo images. A difference image obtaining section generates a difference image between an actually measured depth image and the computed depth image. In a depth image decompressing section of a content processing device, a depth image operation section generates a depth image by operation using the transmitted stereo images. A difference image adding section restores a depth image by adding the computed depth image to the transmitted difference image.

Dependent claims

An image processing device comprising:

a depth image obtaining section configured to obtain data of a depth image actually measured by a camera measuring a distance of a subject and having the distance as a pixel value;
a photographed image obtaining section configured to obtain data of a plurality of photographed images formed by photographing the subject from different viewpoints;
a depth image compressing section configured to compress the data of the depth image using the data of the plurality of photographed images;
and
an output section configured to output the data of the plurality of photographed images and the compressed data of the depth image.

2 more elements

A content processing device comprising:

an image data obtaining section configured to obtain data of a plurality of photographed images formed by photographing a subject from different viewpoints and data after compression of a depth image actually measured by a camera measuring a distance of the subject and having the distance as a pixel value;
a depth image decompressing section configured to decompress the data of the depth image after the compression using the data of the plurality of photographed images;
and
an output section configured to perform predetermined processing using at least the decompressed data of the depth image, and output a result.
