ABSTRACT:
An image read-out and processing apparatus comprises an image read-out section, which carries out a preliminary readout and a final readout, and an image processing section. In the final readout, the amount of light irradiated to an image storage sheet, on which an image has been recorded, and/or the light accumulation time of a photoelectric conversion device is adjusted appropriately in accordance with preliminary read-out image information obtained from the preliminary readout. The image processing section is provided with a color and density correcting device for correcting the final read-out image information such that the color and the density of the image may become appropriate, and for determining the degree of correction, which is carried out on the final read-out image information, in accordance with a parameter, which is set in accordance with the preliminary read-out image information. A parameter correcting device corrects the parameter in accordance with the final read-out image information.
