  • IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD
    Publication number: 20120195513
    Abstract: The present invention relates to an image processing device and an image processing method that enable a set of images of multiple visual points which images form a stereoscopic image to be recognized in a case of multiplexing and coding the images of the multiple visual points which images form the stereoscopic image even when the coded data is decoded from the middle in a decoding device. A coding system performs coding such that a picture of a random access point is a picture of an L-image of an LR pair and a picture of an R-image is a picture subsequent to the picture of the random access point in coding order. The present invention is applicable to devices for coding stereoscopic images, for example.

  • IMAGE INFORMATION DECODING APPARATUS AND IMAGE INFORMATION DECODING METHOD FOR MOTION PREDICTION AND/OR COMPENSATION OF IMAGES
    Publication number: 20120189219
    Abstract: The present invention is directed to an image information encoding apparatus, used in receiving compressed image information through network media when processing of such compressed image information is performed on storage media. A picture sorting buffer delivers information of picture type of frame Picture_type to a picture type discrimination unit. The picture type discrimination unit transmits command to a motion prediction/compensation unit on the basis of that information. The motion prediction/compensation unit generates predictive picture by using filter coefficients having the number of taps lesser than that of P picture with respect to B picture for which operation quantity and the number of memory accesses are required to more degree as compared to P picture on the basis of that command.

  • IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD
    Publication number: 20120114260
    Abstract: The present invention relates to an image processing device and an image processing method whereby encoding efficiency of image prediction encoding can be improved. A horizontal processing unit 31 performs horizontal packing as horizontal processing to manipulate the horizontal-direction array of pixels of each of a first thinned-out image and a second thinned-out image arrayed in checkerboard fashion, obtained by thinning out the pixels of each of a first image and a second image different from the first image every other line in an oblique direction, wherein pixels of first and second thinned-out images are packed in the horizontal direction. A combining unit 33 generates a combined image which is combined by adjacently arraying the post-horizontal processing first and second thinned-out images after horizontal processing, as an image to serve as the object of prediction encoding.
