SOLUTION: Light entering the lens of the camera is adjusted through the use of the plural polarizing means. In a room where an iris recognizing system constituted like this is installed, only light necessary for catching the video of a customer and a precise iris pattern enters the lens of the camera through a polarizing means. For example, a polarizing glass 52 of which the polarizing direction is vertical is used for the side wall and the door of an ATM box 1, and a polarizing glass 53 of which the polarizing direction is vertical is provided for the outer side of the lens of the camera 13a. Thereby the brightness of the background of the customer is interrupted so that the camera 13a instantaneously specifies the face and the eye of the customer.
