An image processing apparatus uses a camera to pick up images of an image pickup target illuminated by a transmission type illumination, via optical filters, and then allows a spectral characteristic estimating section and a pigment amount estimating section to calculate a physical amount relating to the image pickup target for each pixel of the image pickup target, on the basis of the picked-up multiple band images. On this occasion, the image processing apparatus uses the optical filters the number of which is equal to the number of independent components of the calculated physical amount.
