Abstract
An image reading apparatus and method is realized which can obtain light correction data with accurately and without involving a complicated operation. A turret including balance filters for a negative film and for a positive film, respectively, is provided in the image reading apparatus. When light correction data is acquired, the turret is controlled so that the positive-film balance filter is inserted and located on an optical axis L of light emitted from a lamp, and in a state in which a photographic film is not set in a film carrier, light correction data is generated based on image data outputted from a line CCD. At the time of reading images on the photographic film, when a negative film is used as the photographic film, the negative-film balance filter is inserted and located on the optical axis L, and when a positive film is used as the photographic film, the positive-film balance filter is inserted and located on the optical axis L. Further, light correction is performed for image data inputted from the line CCD using the above-described light correction data.
