摘要

PROBLEM TO BE SOLVED: To provide a pattern recognition device capable of efficiently detecting any objects to be recognized at a low cost when an arbitrary region present in a target image is detected as a particular object to be recognized.

SOLUTION: Characteristic detection means 101 to 104 hierarchically detect a plurality of characteristics constituting a predetermined pattern included in an input signal. Reference data holding means 122 to 124 hold a plurality of pieces of reference data corresponding to the plurality of the characteristics. The data setting means 111 to 114 set data used for detection of a target characteristic based on the reference data held in the reference data holding means 122 to 124 and the characteristic detection result of the target characteristic at the previous stage.
