ABSTRACT:
Shading data are captured in a state where there is no developed film between a light source and a line sensor. During calibration, a negative base area on the film is positioned between the light source and the line sensor, and signal levels of colors of color signal data corresponding to three primary colors transmitted through the negative base area are controlled to be substantially equal. While the film is transported, the color signal data indicating a frame image are obtained in the calibrated state, and shading correction is performed for the color signal data according to the obtained shading data.
