发明名称 Method of reading photographic film and photographic film reading apparatus for implementing the method
摘要 A photographic film reading apparatus reads a photographic image from a photographic image area disposed at a width-wise center of a photographic film and a code from a code area disposed at a width-wise end of the film. The apparatus includes a photoelectric converging sensor adapted for reading the photographic image area and the code area simultaneously, an image data dividing section for dividing the image data obtained by the photoelectric converting sensor between photographic image data corresponding to the photographic image area and code image data corresponding to the code area, a first shading correcting section for effecting a shading correction on the photographic image data by using a first shading correction coefficient, a second shading correcting section for effecting a shading correction on the code image data by using a second shading correction coefficient which is set independently of the first shading correction coefficient, and a code decoding section for decoding a code of the shading-corrected code image data by using the shading-corrected code image data.
