ABSTRACT:
The amount of light emitted from a lamp is adjusted by a turret and a diaphragm for each light of the component colors and is irradiated on a photographic film via a light diffusion box. Light transmitted through the photographic film is made incident on a three-line CCD via a lens unit. In order to read a film image, first, the photographic film is conveyed at high speed in a predetermined direction and is read under a predetermined reading condition (pre-scan), and based on image data obtained by the reading, a recorded position of each image is determined and a reading condition during fine scan is calculated for each image, and each image is read under the calculated reading condition while the film is conveyed at relatively low speed in a direction opposite to the predetermined direction (fine scan).
