摘要： PROBLEM TO BE SOLVED: To allow the actual world pseudo experience of two or more users with the same visual point. SOLUTION: This image information processor for generating a display image according to a visual point designated by a user from preliminarily held image data communicates with a control device having a control part communicable with two or more image information processors for generating the display image to control the visual point information commonly used in the image information processors on the basis of the visual point information from the image information processor. This image information processor comprises a transmission part for transmitting the visual point information to the control part; a receiving part for receiving the visual point information for generating the display image from the control part; and an image generation part for reading the image data corresponding to the visual point information from the preliminarily stored image data for generating the display image, generating the display image, and outputting it to a display part.

摘要： PROBLEM TO BE SOLVED: To store image in an efficient data form by selectively using a data form which uniformly represents an image as the same color, a data form which represents the image in a reversible type or a data form which represent the image as irreversible type and storing it. SOLUTION: Multivalued image data is inputted to an image inputting part 1. This storage system has a 1st storage step which generates 1st image data that uniformly represents an image in a prescribed area which is shown by multivalued image data as the same color and stores it in an image file 21, a 2nd storage step which generates 2nd image data that similarly represents the image in the prescribed area as a reversible type and stores it in the file 21 and a 3rd step which generates 3rd image data that similarly represents the image in the prescribed area as irreversible type and stores it in the file 21. Multivalued image data is stored in the file 21 by selectively using any of the 1st to 3rd storage steps.

摘要： PROBLEM TO BE SOLVED: To easily generate or reproduce shape data for a complicated object by describing the shape of a three-dimensional object and the shape of a space based on information including a three-dimensional position, a direction and a surface color, describing the shape and the shape of the space based on an actually photographed image, making both descriptions coexist and generating a virtual environment. SOLUTION: Whether to generate a geometrical shape model 3a and surface attribute data 3b or to read data separately generated by a different processing is selected and generation is performed or data generated by a different generator are read. Then, whether to generate light beam space data 3c arranged in the virtual environment or to read the light beam space data 3c generated beforehand is selected and generation or read is performed. Then, they are mutually arranged and a three-dimensional world is constructed. At the time, at the time of expressing the virtual environment, elements (coordinate transformation data, the shape data, the surface attribute data and illumination, etc.) for constituting the virtual environment are expressed by a tree structure.

摘要： PURPOSE:To geneate an interpolated image with high accuracy based on multiple viewpoint images. CONSTITUTION:An epipola plane image (EPI) is generated by arranging lines on the same position in sequence of a viewpoint based on images from plural viewpoints. The line to be interpolated is inserted to each line, and corresponding points a1, b1, and c1 are detected by detecting a straight line. At this time, a score is given to each picture element through which the straight line passes corresponding to the number of straight lines detected from remarked picture elements, and as for the picture element in which the correspondence of a picture element which a low score and one with a high score is overlapped, the correspondence with the low point is eliminated. The point on the interpolated line of the straight line consisting of those points is set as the point generated by interpolation. However, the interpolation is performed preferentially starting from the correspondence with the high score by performing interpolation according to the correspondence with the low score in advance and then the interpolated image can be generated.

摘要： PURPOSE:To obtain a continuous picture corresponding to the movement of an observer's visual point by using pictures photographed by plural fixed cameras. CONSTITUTION:A multivisual-point picture obtained by photographing a subject from plural visual points is stored in an input two-dimensional multivisual-point picture storing part 11 and a mutually corresponding point between respective pictures stored in the storing part 11 is detected by a corresponding hyperplane judging part 17. A corresponding hyperplane interpolating processing part 18 applies interpolating processing to picture elements on a corresponding hyperplane specified by the corresponding point so as to generate many interpolated pictures with fine visual point intervals capable of filling the interval of photographing visual points, so that a picture to be smoothly changed in accordance with the movement of a visual point can be obtained.

摘要： PURPOSE:To reduce the burden of following processing as much as possible in the case of dispatching the contour point of a provided binary image to the following processing. CONSTITUTION:The binary image provided from a binary image possessing means 11 is extracted by an outline vector extracting means 12 and smoothed by eliminating any unwanted vector at an outline vector detecting, reducing, smoothing and magnifying means 13. Afterwards, a binary image is generated by a binary image reproducing means 14 based on the outline vector processed by the outline vector detecting, reducing, smoothing and magnifying means 13, and outputted by a binary image output means 15.
