IMAGE INPUT DEVICE AND PERSONAL IDENTIFICATION DEVICE

PROBLEM TO BE SOLVED: To make thin a personal identification device using the vein pattern of the finger, and to easily take measures to an object distance due to the variations of the skin thickness of the finger. SOLUTION: The image of a vein 2 of the finger 1 is taken as a compound eye image through a lens eye 3. A parallax between ommatidium images in the taken compound eye image is detected by a parallax detection part 102. When the parallax exceeds a threshold TH, a reconfiguration method selection part 106 makes a connection processing part 104A of a reconfiguration processing part 103 execute reconfiguration processing by a connection method, and when the parallax is not more than the threshold TH, makes a pixel rearrangement processing part 104B of the reconfiguration processing part 103 execute reconfiguration processing by a pixel rearrangement method.
