Abstract: An object extraction method comprising the steps of comparing each portion of first image data obtained by capturing an extraction object with another portion of the first image data or second image data, thereby generating shape data as an image representing a provisional region of the extraction object in the first image data, and matching a contour of the shape data to a contour of the extraction object by using the first image data and the provisionally generated shape data.

Abstract: An image displaying apparatus includes an image storing unit storing image data containing two or more objects. An extracting unit extracts individual data from the object of the image data. An input unit inputs additional partial image data, and attribute data representing a corresponding relationship of at least part of the image data to the additional partial image data. An associating unit associates the additional partial image data with an individual data of the image data, using the attribute data input via the input unit. A synthesizing unit modifies a data content regarding at least part of the image data, which is associated by the associating unit, and synthesizes the modified content with the image data stored in the image storing unit.

Abstract: A video encoding apparatus is provided with a resolution converting section, an encoding section, and a transmitting section. The resolution converting section enlarges or reduces a binary picture which represents the shape of an object. The encoding section encodes a binary picture reduced by the resolution converting section. The reduction ratio used by the resolution converting section is encoded, and the transmitting section transmits this encoded reduction ratio along with encoded data on the binary picture. The amount of encoded data produced from the encoding section is controlled by changing the enlargement/reduction ratio used by the resolution converting section.
