ABSTRACT:
An image reading apparatus in which highly accurate image reading can be carried out by using a line sensor. Light irradiated from a light source is divided into visible light or infrared light by a visible light filter or an infrared light filter, and irradiated onto an image frame of a photographic film. The light transmitted through the image frame is reflected by a mirror and made incident on a linear CCD via a lens unit. At this time, sub-scanning of the image frame is carried out by moving the mirror while the photographic film (i.e., image frame) is stopped, and a frame image is read by the linear CCD. In this way, image reading is carried out by using visible light and infrared light while the image frame is stopped. Accordingly, there is no positional displacement between visible light image data and infrared light image data, and the visible light image data can be corrected with high accuracy based on the infrared light image data.
