摘要： An object detection apparatus, a program, and an integrated circuit enable the contour of an object to be detected in an appropriate manner in an image including an object and its background with almost no contrast between them in a predetermined direction of the image. A vertical direction edge extraction filter in a filtering unit extracts, from an input image, a contour component in a first direction (e.g., vertical direction) of the image. A horizontal direction continuity detection unit in the filtering unit detects, in a second direction (e.g., horizontal direction) perpendicular to the first direction, the continuity of the contour component extracted by the vertical direction edge extraction filter. An object area detection unit detects (estimates) the contour of the object in the image based on the continuity of the contour component in the second direction (e.g., horizontal direction) detected by the horizontal direction continuity detection unit.

摘要： An address comparator stores an address of data read out by a host system. Also, a buffer reads out the data from a memory and stores the data. If an address of data which is expected to be newly read out by the host system is included in addresses which have already been stored in the address comparator, the host system 1 newly reads out the data from the buffer, not from the memory. As a result, it is possible to eliminate or lessen the possibility of unintentional rewriting of data which is likely to be caused due to repeated readout of data.
