Image reading and processing apparatus, digital printing apparatus using the image reading and processing apparatus, and image reading and processing method

摘要

An image reading and processing apparatus which reads an original image photographed on a film, and performs image processing on the read image to obtain output data. This apparatus is used in a digital printing apparatus based on an image reading and processing method which prevents or reduces occurrence of a failure to output an image portion actually recorded on the film to a printer or the like, i.e., chipping off the image. From a picture frame of an original image, first image data is read so that the first image data includes data on a picture area and a non-picture area around the picture area. Boundaries of the picture area is determined from the first image data obtained by reading, and second image data is extracted within an image data extraction area which is set according to the determined boundaries of the picture area. Image processing is performed on the extracted second image to obtain output data.
