    摘要： When a retrieval condition of an attribute list is input from a user interface unit to a retrieval processing unit, the attribute list stored in an attribute list storing unit is retrieved in the retrieval processing unit. Thereafter, attribute information conforming to the retrieval condition is output to and displayed on a displaying unit. Thereafter, when a retrieval condition of the similarity retrieval is input from the user interface unit to the retrieval processing unit, image data stored in the image information storing unit is retrieved in the retrieval processing unit, and specific image data relating to a characteristic descriptor set conforming to the retrieval condition is selected in the retrieval processing unit. Thereafter, the specific image data is output to and displayed on the displaying unit.

    摘要： A lateral directional difference calculating unit 21 calculates a change degree between pixel levels of pixels adjacent to each other through a boundary of a decoded block and a block adjacent to the decoded block in a lateral direction and calculates a change degree between pixel levels of pixels placed in the block adjacent to the decoded block in the lateral direction, a lateral directional continuity judging unit 23 judges the continuity between the decoded block and the block adjacent to the decoded block in the lateral direction. A longitudinal directional difference calculating unit 22 and a longitudinal directional continuity judging unit 24 are operated in the same manner, a block continuity judging unit 25 judges the continuity between the decoded block and each block adjacent to the decoded block, and an error macro-block judging unit 26 detects an error macro-block according to a judging result of the block continuity judging unit 25.
