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.

1. Field of the Invention
The present invention relates to an image reading method and apparatus, and particularly to an image reading method and apparatus, in which light is illuminated onto a developed photosensitive material, and based on the light transmitted through the photosensitive material, images recorded on the photosensitive material are read.
2. Description of the Related Art
FIG. 1 is an outside view of an image reading apparatus according to an embodiment of the present invention.
FIG. 2 is a cross-sectional view of an optical system of the image reading apparatus according to the embodiment of the present invention as seen from the front of the apparatus.
FIG. 3 is a cross-sectional view of the optical system of the image reading apparatus according to the embodiment of the present invention as seen from a side of the apparatus.
Referring now to the Figures, an embodiment of the present invention will be hereinafter described in detail.
As shown in FIG. 1, an image reading apparatus according to the embodiment of the present invention includes a line CCD scanner 14. The line CCD scanner 14 is placed on a work table 27 with an image processing section 16, a mouse 20, two types of keyboards 12A and 12B, and a display 18 being provided thereon.
One of the keyboards, the keyboard 12A, is embedded in a work surface 27U of the work table 27. Another keyboard 12B is accommodated in a drawer 24 of the work table 27 when not in use. When using the keyboard 12B, it is taken out of the drawer 24 and placed over the keyboard 12A. At this time, a cord of the keyboard 12B is joined to a jack 110 connected to the image processing section 16.
