System and method for correcting aberration of lenses through which images are projected
First Claim
1. An aberration correcting method wherein after an image of a subject projected through a first lens is imaged by imaging means in which a photographic photosensitive material is loaded, aberration correction is performed with respect to image data obtained by projecting through a second lens the subject image recorded on the photographic photosensitive material by the imaging, and by reading of the subject image by image reading means, comprising the steps of:
- obtaining information on the aberration of said first lens and information on the aberration of said second lens; and
with respect to the image data representing the subject image and obtained by reading with said image reading means, simultaneously correcting declines in image quality of the subject image represented by the image data, which declines are due to the aberrations of said first and said second lenses, on the basis of the obtained information on the aberrations of said first and said second lenses.

Abstract
In a case where aberrations of a camera lens are large, and imaging-center coordinates and reading-center coordinates coincide with each other or are located in proximity to each other within an allowable range, and trimming was not effected or center trimming was not effected, correction parameters for correcting the aberrations of the camera lens and correction parameters for correcting the aberrations of a scanner lens are integrated, and the deterioration of image quality caused by the aberrations of the camera lens and the deterioration of image quality caused by the aberrations of the scanner lens are corrected simultaneously by using the integrated parameters.

7. An aberration correcting method wherein after an image of a subject projected through a first lens is imaged by imaging means in which a photographic photosensitive material is loaded, aberration correction is performed with respect to image data obtained by projecting through a second lens the subject image recorded on the photographic photosensitive material by the imaging, and by reading of the subject image by image reading means, comprising the steps of:
-
obtaining information on the aberration of said first lens and information on the aberration of said second lens;
determining whether or not an aberration amount of said first lens is greater than or equal to a predetermined aberration amount; and
if the aberration amount of said first lens is greater than or equal to the predetermined aberration amount, with respect to the image data, simultaneously correcting declines in the image quality of the subject image represented by the image data, which declines are due to the aberrations of said first and said second lenses, on the basis of the information on the aberrations of said first and said second lenses, and if the aberration amount of said first lens is less than the predetermined aberration amount, with respect to the image data, correcting the decline in the image quality of the subject image represented by the image data, which decline is due to the aberration of said second lens, on the basis of the information on the aberration of said second lens. - View Dependent Claims (8, 9, 10, 11)

12. A system for image processing, wherein an image of a subject has been recorded onto an imaging material by projecting through an imaging lens, said system comprising:
-
a scanning unit configured to scan said imaging material, wherein said scanning unit includes a scanning lens in which said image is projected through; and
an image processing unit configured to correct aberrations of said imaging and scanning lenses. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
