Abstract
An image reading method and apparatus allow reading light to be incident on a film to obtain projected light and read the thus obtained projected light photoelectrically to perform reading of an image recorded on the film. In the method and apparatus, at least one of a scratch and a foreign matter on the film is detected based on two respective reading results obtained using types of reading light in different states of diffusion such as a parallel light and a perfectly diffused light from two light sources, respectively. The method and apparatus are capable of surely detecting a scratch on the film, or dirt or foreign matter adhered to the film and correcting it as required, whereupon high-quality images having no image deterioration due to the scratch, the dirt or foreign matter can be reproduced in a consistent manner.
