Abstract
An image processing system includes a photographing apparatus and a processing apparatus. The photographing apparatus includes LEDs for emitting light with characteristics of spectroscopic distributions varied in a visible light area, an image pick-up device unit which picks-up a subject image that is illuminated by the LEDs and is formed by an image pick-up optical system and which outputs an image signal, and a control unit. The control unit sequentially lights-on the LEDs upon an instruction for photographing a subject spectroscopic image being input from an operating switch, picks-up the image, and thus controls the operation for capturing subject spectroscopic images. The processing apparatus includes a calculating device which performs a desired image calculation based on the image signal.
