摘要： An image generation method for generating image information of an image C by using an image A and an image B having a resolution higher than that of image A. Image C having the same resolution as image B is generated by enlarging image A; presence or absence of a point in image B corresponding to each pixel position of image C and the position of the relevant corresponding point are estimated; and to each pixel position in image C for which it is estimated that there is a corresponding point, image information of the corresponding position in image B is assigned. It is possible to generate image information at each pixel position in image C for which it is estimated in the corresponding point estimation that there is no corresponding point, by using the image information assigned according to an estimation result that there is a corresponding point.

摘要： A method for encoding an image using an intraframe prediction is provided which includes selecting a gradient of a pixel value that is indicated by an image signal to be predicted among a plurality of gradient candidates, generating a predicted signal by applying a gradient in accordance with the distance from a prediction reference pixel based on the gradient, intraframe-encoding the image signal to be predicted based on the predicted signal, and encoding information indicating the size of the selected gradient. Alternatively, the method includes estimating the gradient of a pixel value that is indicated by an image signal to be predicted based on an image signal which has already been encoded, generating a predicted signal by applying a gradient in accordance with the distance from a prediction reference pixel based on the gradient, and intraframe-encoding the image signal to be predicted based on the predicted signal.

摘要： A video encoding apparatus used in encoding of a multi-viewpoint image. The apparatus generates a synthetic image for a camera used for obtaining an encoding target image, by using an already-encoded reference camera image having a viewpoint different from the viewpoint of the camera used for obtaining the encoding target image, and disparity information between the reference camera image and the encoding target image, thereby encoding the encoding target image. A predicted image for a differential image between an input image of an encoding target area to be encoded and the synthetic image generated therefor is generated, and a predicted image for the encoding target area, which is represented by the sum of the predicted differential image and the synthetic image for the encoding target area, is generated. A prediction residual represented by a difference between the predicted image for the encoding target area and the encoding target image of the encoding target area is encoded.

摘要： By using parallax compensation which performs prediction by using parallax between video images, the video images are encoded as a single video image. Reference parallax for a target image to be encoded is set, wherein the reference parallax is estimated using a reference image; area division in an image frame is set; parallax displacement for each divided area is set, wherein the parallax displacement is the difference between the reference parallax and parallax for the parallax compensation; data of the area division is encoded; and data for indicating the parallax displacement is encoded. During decoding, reference parallax for a target image to be decoded is set, wherein it is estimated using a reference image; data for indicating area division, which is included in encoded data, is decoded; and data of parallax displacement, which is included in the encoded data, is decoded for each area indicated by the area division data.
