METHOD FOR ENCODING A PLURALITY OF INPUT IMAGES, AND STORAGE MEDIUM HAVING PROGRAM STORED THEREON AND APPARATUS

摘要

A method for encoding a plurality of input images is provided. The method includes the steps of generating a first residual image from a difference between a first input image and a corresponding first predicted image, converting, into a remainder, a pixel value included in a region of the first residual image which should be defined by a remainder, generating a second residual image from a difference between a second input image and a corresponding second predicted image, converting, into a remainder, the pixel value included in a region of the second residual image which should be defined by a remainder, and coding the first residual image after the conversion, the second residual image after the conversion, and additional information specifying the region which should be defined by a remainder in each of the first residual image and the second residual image.

1. A method for encoding a plurality of input images, comprising:
obtaining a plurality of first input images each containing first information on an object and a plurality of second input images each containing second information on the object, the plurality of second input images corresponding to the plurality of first input images, respectively, the second information being different from the first information; for one of the first input images, calculating a first predicted image from information contained in at least one of another one of the first input images and a corresponding one of the second input images; generating a first residual image from a difference between the one of the first input images and the corresponding first predicted image; specifying a region whose pixel value should be defined by a remainder, among pixels constituting the first residual image, based on a pixel value of the first residual image; converting, into a remainder, the pixel value included in the specified region of the first residual image which should be defined by a remainder; for one of the second input images, calculating a second predicted image from information contained in at least one of another one of the second input images and a corresponding one of the first input images; generating a second residual image from a difference between the one of the second input images and the corresponding second predicted image; specifying a region whose pixel value should be defined by a remainder, among pixels constituting the second residual image, based on a pixel value of the second residual image; converting, into a remainder, the pixel value included in the specified region of the second residual image which should be defined by a remainder; and encoding the first residual image after the conversion, the second residual image after the conversion, and additional information specifying the region which should be defined by a remainder in each of the first residual image and the second residual image.
