Abstract
A pattern identification apparatus computes, for each of multiple data elements in input information stored in an array, an accumulated information value corresponding to the position of the data element in the array, writes each of the computed accumulated information values into one of multiple storage units provided in advance, based on the positions of the corresponding data elements in the array, reads out, in parallel and one each from the storage units, the accumulated information values decided based on the positions in the array that corresponds to a local area, the local area being an area within an area of interest in the input information, calculates a feature amount of the local area using the accumulated information values read out from the storage units, and determines whether or not a predetermined pattern is present in the area of interest by comparing the calculated feature amount with pre-set dictionary data.
