Abstract
In an image reproducing apparatus, an image recorded on a negative film is subjected to optical measurement by an optical measuring device. The data obtained by the optical measurement is stored in a photometric data memory for each type of film which is judged by a DX code reader and a film type detecting device. In the apparatus, a difference in characteristics between a reference film and the negative film is calculated by a film characteristic difference calculating device, and the image characteristic amount of the image is calculated by an image characteristic amount calculating device. In a film type correction amount calculating device, a correction value is calculated based on the calculated difference in the film characteristics and the image characteristic amount to compensate for a decrease in the quality of the printed image due to the difference in the film characteristics. In an exposure condition determining device, exposure conditions are determined based on reference exposure conditions input from a reference exposure condition setting device, photometric data selected by a photometric value selecting device, and the above-described correction value. Accordingly, images having proper image quality can be reproduced from various films having different film characteristics.
