  • Patent number: 7102649
    Abstract: An image filling method for reducing filling process in producing animation. The image filling method includes the steps of separating a reference line drawing and a line drawing into first and second closed regions; extracting at least one feature amount of the first and second closed regions; calculating variations of feature amounts between every combination of the first and second closed regions, sorting the first closed regions in ascending order by the variation of the feature amount for each of the second closed regions; generating color candidate lists for each of the second closed regions, wherein duplication of the color information is eliminated; filling each of the second closed regions with a color which is on the top of the color candidate list.
    Type: Grant
    Filed: February 4, 2004
    Date of Patent: September 5, 2006
    Assignee: Nippon Telegraph and Telephone Corporation
    Inventors: Naoya Kotani, Masakatsu Aoki, Kyoko Teranishi

  • Patent number: 6157387
    Abstract: An image generating apparatus comprising a multi-plane buffer comprising a plurality of planes, and can record R, G, B, A and Z values as pixels, and a multi-plane buffer processor which stores in said multi-plane buffer in sequence from closest distance from a vantage point a plurality of defocus data which is data consisting of object model data that has been at least coordinate converted, hidden surface processed, and defocus processed, and which assigns R, G, B, A and Z values to each pixel, this object model data being derived from an object whose positional relationships are to be represented from a vantage point using depth of field, which is the effective focus range within which the object is focused.
