PROBLEM TO BE SOLVED: To provide an image recognition system by which a group of inputted images can be correctly discriminated without depending on an angle between an input part space and a dictionary part space. SOLUTION: The image recognition system is provided with an input representative vector generation part 52 for generating an input representative vector 52A as an optional vector belonging to an input partial space including input feature data 51A, an input main component data generation part 53 for generating K input main component vectors 53A indicating difference between K pieces of optional input feature data 51A and the input representative vector 52A, a distance calculation part 54 for calculating a distance value between the input part space and the dictionary part space from the input main component vector 53A, the input representative vector 52A, L dictionary main component vectors 63A stored in a dictionary storage part 3 and a dictionary representative vector 62 and a discrimination part 55 for outputting a recognition result 5A based on the calculated distance value.
