The image correction apparatus includes an image reading unit for reading a print image of an original image, where a mark is given to a defect on an image and an image correction unit for correcting image data of the original image by utilizing the position of the mark on a read image read by the image reading unit. The image correction apparatus efficiently corrects an image defect visually recognized on the print image without using an infrared ray, when the print image is output from image data of the original image.

A photographic film, which is accommodated in a cartridge provided with a storing element for storing printing information, is separated from the cartridge. An identification mark for having the film and the cartridge correspond to one another is applied to the film. The printing information stored in the storing element is read by a first reading device. The printing information read by the first reading device and the identification mark are stored in correspondence with each other. The printing information corresponding to the identification mark applied to the film is read by second reading device. In accordance with the printing information read by the second reading device, an image recorded on the photographic film is printed onto a photographic printing paper in a state in which the cartridge and the photographic film are separated from each other.

The present invention includes a digital image reading apparatus and method which can determine the characteristic value of film with pinpoint accuracy and can properly determine the image processing conditions for each frame using the characteristic value even if the images recorded on the film have color failure. The present invention provides an image reading apparatus which comprises a reader for photoelectrically reading the images recorded on a film and outputting the images as image data; a condition setter for creating the density histograms of the images of each frame read by the reader, calculating the characteristic value of the film from the density histograms of a plurality of frames and determining the image processing conditions for an image of each frame from the characteristic value of the film and the image data of the images of each frame, wherein the characteristic value of the film is calculated by approximating a relationship among the three primary colors of a specific point on a side where a cumulative frequency is low and a specific point on the side where the cumulative frequency is high which are obtained from the density histograms of the images of the respective frames by means of a method of least squares. It is preferable that the condition setter calculates the characteristic value of the film using the maximum density and the minimum density obtained from the density histograms of the respective frames.
