Abstract
When an image scanner scans an image recorded on an advanced photo system™ film, it determines spectral transmittance of a portion of the film, which is not exposed but developed, then sets parameters, such as masking parameters and &ggr; correction parameters, to be used in image signal processes on the basis of the spectral characteristics. Thereafter, the image is read by a CCD and image data is outputted. The film scanner applies the image signal processes to the image data using the parameters set in accordance with the spectral transmittance.
