Abstract

PURPOSE:To facilitate an easy retrieval for the pattern information such as the pattern photo and the like, by using the run length for the retrieval parameter. CONSTITUTION:The pattern information of a retrieval subject is generated from the pattern generator PG, and the run length distribution function F(l) is produced by the run length distribution producer RLF2 to be set to the register RG. At the same time, the density level information is sent successively to the buffer memory BM from the picture memory M with every picture element to be rearranged in a 2-dimensional way. Then the pattern information of the specified region of MXN picture element constitution is extracted, and the run length distribution function F'(l) is produced by the run length distribution producer RLF1. A comparison is given through the comparator CMP between the functions F(l) and F'(l). When the difference between these functions is within a prescribed value, it is decided that the pattern information is retrieved at the specified picture region. And the result of decision is sent to the display part. In such way, the retrieval of pattern information is possible in a simpler way than conventional.
