IMAGE READING DEVICE

The image reading device has a scan control processor that performs a coarse scanning operation, in which a film is intermittently moved so that a line sensor scans the image, in order to obtain an optimum exposure time and a color correction coefficient. The coarse scanning operation includes a first reading mode and a second reading mode. In the first reading mode, a reading pitch for a center portion of the image is finer than that for peripheral portions of the image. In the second reading mode, the whole of the image is coarse-scanned with a uniform pitch. Due to the coarse scanning operation according to the first reading mode, an exposure measurement is performed with the center portion of the image being weighted.
