Abstract
A photograph processing device comprises an exposing section for printing an image on a light-sensitive material in accordance with exposure conditions, a processor section for performing developing, fixing, washing and drying operations with respect to the printed light-sensitive material, a density measuring unit provided in the vicinity of the light-sensitive material exit side of the processor section for photometering the light-sensitive material to provide an image density signal free from the influence of temperature that is caused by subjecting the light-sensitive material to the drying operation, and an exposure condition correcting unit for correcting the exposure conditions in accordance with the image density signal outputted from the density measuring unit. The influence of temperature is avoided by cooling the light-sensitive material to be photometered or correcting the image density of the light-sensitive material that is measured by the density measuring unit, and the exposure conditions are corrected in accordance with the image density signal free from the influence of temperature; therefore, optimal exposure conditions can be set.
