  • Patent number: 6879323
    Abstract: Featured is a device for generating a 3-D model of a target object detects size, position, and direction of the target object in an input image. The device calculates the position of each vertex of a 3-D rough geometric model projected onto a 2-D plane in the detected size, position, and direction, as well as onto a 2-D plane in a predetermined size, position, and direction. The device also modifies the input image based on a correspondence relationship between the position of each vertex of the 3-D rough geometric model calculated by the first calculation means and the position of each vertex of the 3-D rough geometric model calculated by the second calculation means to generate a texture images and maps the texture image to the 3-D rough geometric model.

  • Patent number: 6587593
    Abstract: An image processing device of the present invention is provided with an area position specifying device and a computing device. When the user specifies a desired object by using the area position specifying device, the computing device generates an emphasized image, in which the specified object is emphasized, and a line image, and the computing device further produces a composite image of these images so as to achieve an illustration image. In addition to the line image, the emphasized image is produced so that it is possible to emphasize an object desired by the user regardless of a state of the line image; consequently, it is possible to generate a natural illustration image in accordance with the actual image.

  • Patent number: 6332038
    Abstract: The present image processing device includes an image obtaining device which obtains an electronic image (still image) or a series of electronic images (moving image), an image extraction processing device which performs image extraction processing for extracting from the image obtained by the image obtaining device a specified object domain an operator wishes to cut out, and a result output device which outputs an image extracted by the image extraction processing device. The image extraction processing device sets two mutually exclusive provisional domains in the obtained image, and, based on separability of the provisional domains, extracts a partial image containing the specified object domain.
