摘要:
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.

摘要:
Rectangles R(i−1), R(i), and R(i+1) are set to surround three temporally continuous frames f(i−1), f(i), and f(i+1). Difference images fd(i−1, i) and fd(i, i+1) are obtained on the basis of the inter-frame differences between the current frame f(i) and the first reference frame f(i−1) and between the current frame f(i) and the second reference frame (i+1). Background regions are respectively determined for polygons Rd(i−1, i)=R(i−1) or R(i) and Rd(i, i+1)=R(i) or R(i+1), and the remaining regions are selected as object region candidates. By obtaining the intersection between these object region candidates, an object region O(i) on the current frame f(i) can be extracted.

An alpha-map encoding apparatus includes a first down-sampling circuit (21) for down-sampling an alpha-map signal which represents the shape of an object and the position in the frame of the object at a down-sampling ratio based on size conversion ratio information, an up-sampling circuit (23) for up-sampling the alpha-map signal at an up-sampling ratio based on size conversion ratio information given to restore the down-sampled alpha-map signal to an original size, and outputting a local decoded alpha-map signal, a motion estimation/compensation circuit (25) for generating a motion estimation/compensation signal on the basis of the previous decoded video signal and a motion vector signal, a second down-sampling circuit (26) for down-sampling the motion estimation/compensation signal at the down-sampling ratio, a binary image encoder for encoding the alpha-map signal down-sampled by the first down-sampling circuit to a binary image in accordance with the motion estimation/compensation signal down-sampled by the second down-sampling circuit, and outputting an encoded binary image signal, and a multiplexer for multiplexing and outputting the encoded binary image signal and the up-sampling ratio information.
摘要:
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.
