PURPOSE:To obtain a high recognition ratio in a recogntion device using a neural network. CONSTITUTION:Two-dimensional bit image generated by an input part 15 is processed by a 4-layer constitutional neural network and an image is recognized. A neuron on a first layer 17 is coupled only with the neuron on a second layer 18 aligning in a specific direction continuously. Then, a line segment in a peculiar direction is extracted by the second layer 18. Further, the second layer 18 is divided into plural areas, and the neuron in the same area is coupled with the same neuron on a third layer 19. Then, the output condition of the neuron on the third layer 19 shows that an extracted line segment exists any extent and at any position in the image. The third layer 19 and a fourth layer 20 are coupled totally, and by learning, the image is recognized.
