ABSTRACT:
The present invention provides high-accuracy image input capable of correcting for uneven lighting due to the shape of the subject, its reflectivity, its positioning and ambient light conditions, without increasing the scale of the circuitry or its costs. The image input apparatus of the present invention has an LED that projects light onto the subject, a sensor including a plurality of pixels arranged two-dimensionally and that detects light reflected back from the subject, and a controller that changes the LED irradiation conditions in a cycle longer than that for a single screen.
