Abstract: PROBLEM TO BE SOLVED: To easily realize a super-resolution effect. SOLUTION: When the frame rate of the display device of an image display part 13 is F and the number of display pixels is (x×y), an image input part 11 inputs an image of which the frame rate is F and the number of pixels is (ix×jy), and converts the image into an input frame Fa of an inner data format. An image conversion part 12 converts the resolution of the input frame Fa supplied from the image input part 11 into resolution which can be displayed on the image display part 13, and generates a display frame Fb ((x×y) pixels). When the image conversion part 12 performs conversion processing of prescribed resolution based on the moving speed of the image in each prescribed block, a visual effect that an observer viewing the image of the display frame Fb recognizes the resolution exceeding the displayed resolution can be realized.

Abstract: PROBLEM TO BE SOLVED: To provide a device and a method for efficiently detecting a corresponding point among a plurality of images captured from a plurality of different points of view. SOLUTION: Block division is performed on an L image out of the L image and an R image which are captured from different points of view. A degree of similarity between blocks of the L image and an image area configuring the R image is calculated. A likelihood of the corresponding image area candidate of the R image for each of blocks configuring adjacent blocks of the L image is calculated based on a positional relationship of the corresponding image area candidate. Further, evaluation values of the corresponding image area candidates of the R image for the blocks of the L image are calculated from the degree of similarity and the likelihood, and by comparing the calculated evaluation values, an image area of the R image corresponding to the blocks of the L image is determined. Further, by using a reduced image or using dynamic programming, further speedup is attained. COPYRIGHT: (C)2011,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To more simply detect deviation in photographing timing of a stereo camera to be performed.SOLUTION: An image obtained by imaging a presentation signal in which luminance is periodically varied at a predetermined frequency by two right and left cameras configuring a stereo camera is input to a producing part 91. The producing part 91 produces right and left capture signals indicating a temporal change of luminance of the presentation signal from the supplied right and left images. When a frequency of the presentation signal is larger than a Nyquist frequency of a frame rate of the camera, a filter processing part 93 extracts right and left folding signals of a specific frequency from the capture signal by a filtering process. A matching processing part 94 detects a phase deviation of the right and left folding signal, then a deviation amount calculating part 95 detects a deviation of imaging timing of the camera from the phase deviation of the folding signal. This invention is applicable to a signal processing apparatus.
