ABSTRACT:
According to the boundary detector of this invention, in order to perform high-speed boundary detection processing for image data read out from a frame memory comprising a plurality of memory planes, image data having a predetermined unit data length, at identical positions from the plurality of memory planes in the frame memory, are compared, by a comparator, with input boundary condition data for a corresponding one of the plurality of memory planes, to produce boundary data. By using all the boundary data, a boundary bit position is detected according to input detection mode designation data, and boundary bit position data representing a detected boundary bit position is output. The boundary detector further includes a generator for generating the boundary data when it is used in boundary detection processing. However, when the boundary data is not used for this purpose, mask data selected on the basis of the memory plane designation data is output as the boundary data, by the generator. Therefore, the memory plane as an object subjected to boundary detection processing can be arbitrarily designated.
