摘要： PROBLEM TO BE SOLVED: To provide an image processing method, generating a virtual visual point image of high quality even in the presence of an occlusion area. SOLUTION: Images taken by cameras 11a and 12a are separated to order-corresponding image data Pe1a and Pe2a and non-order-corresponding image data Pe1b and Pe2b. A DP matching processing part 29 independently performs DP matching of these data. An area-based virtual visual point image generation part 30 generates, on the basis of the matching results, pixel values of a virtual image using pixel values out of the occlusion area.

摘要： PROBLEM TO BE SOLVED: To make images correspond to each other with high precision. SOLUTION: A template deformation part 55 generates plural deformed templates by linear interpolation from a template inputted from a template setting part 53 and inputs them to matching arithmetic parts 54-1 to 54-n. The matching arithmetic parts 54-1 to 54-n perform template matching on an epipolar line by using an image of the epipolar line among reference images stored in image memories 52-1 to 52-n and the deformed templates. Selection parts 56-1 to 56-n determines the deformed template having the highest similarity according to the result of the template matching and regards the current coordinate values as parallax.

摘要： PROBLEM TO BE SOLVED: To achieve more realistic remote dialogue with a feeling of presence without complicating the entire system. SOLUTION: A photographic object is picked up from mutually different angles by at least two cameras, foreground image areas including the photographic object and their background image areas are separated, respectively, from the respective picked up images, mapping is performed by every pixel position while associating with the photographic object among the respective separated foreground image areas, relative positional information indicating relative positional relation of the photographic object to the respective cameras is generated, a pixel position constituting a virtual viewpoint image which should be newly generated according to the generated relative positional information and its luminance components are calculated from mutually mapped pixel positions the luminance components and the virtual viewpoint image to be constituted of the calculated pixel position and its luminance components is transmitted to the outside.

摘要： PROBLEM TO BE SOLVED: To provide a constitution capable of determining compatibility of a floodlight pattern image for distance measurement in a stereo-image method, and capable of generating a highly accurate distance image. SOLUTION: A floodlight pattern for three-dimensional shape measurement is evaluated by a pattern changing rate, a characteristic quantity, a dispersion value, pattern matching or the like, to determine the pattern, and thereby mismatching in inter-image correspondence or in distance image generation processing is removed to enable to generate the highly accurate distance image. A pattern changing rate, a characteristic quantity, or pattern matching is executed based on a photographed image of a measuring object on which the generated floodlight pattern is projected, to evaluate the photographed image. If the image is judged to be incompatible, generation of mismatching is suppressed in generation processing of the distance image by a feedback constitution for generating and floodlighting a new pattern, to thereby enable to generate the highly accurate distance image.
