Abstract
A patch image for calibration information is printed and exposed onto a film in advance and the image is formed in the same way as a frame image by heat development processing. In a case in which an image data input to a data sorting portion is determined to be a patch image, the data is transmitted from the data sorting portion to a correction value operating portion and a curve (γ curve) of exposure to be referenced and a γ curve based on the read patch image are compared. Then, correction is operated and the corrected value is transmitted to a data converting portion. The image data of each frame is corrected in accordance with the correction value.
Claims20
An image processing method, comprising the steps of:
- exposing a calibration pattern outside an image exposure area of a photosensitive material for photographing;
- exposing an image inside the image exposure area to form a continuous tone image;
- developing the exposed image and the exposed calibration pattern;
- digitally reading a formed image and the calibration pattern in substantially a same manner after development processing and creating digital image data and digital calibration pattern data;
- and
- using the created digital calibration pattern data, correcting the digital image data.
An image processing method, comprising the steps of:
- exposing a calibration pattern outside an image exposure area of a photosensitive material for photographing;
- digitally reading a formed image and the calibration pattern after development processing in substantially a same manner and creating digital image data and digital calibration pattern data;
- converting the created digital calibration pattern data into data which does not depend on the characteristic of said photosensitive material;
- and
- using the converted data, correcting the digital image data.
An image reading method, comprising the steps of:
- exposing a calibration pattern outside the image exposure area of a photosensitive material for photographing, said exposing being performed one of before and after the image is exposed onto the photosensitive material for photographing;
- digitally reading the formed image and the calibration pattern after development processing and creating digital image data and digital calibration pattern data;
- and
- adding the calibration pattern to said digital image data so as to be output.
An image processing method, comprising the steps of:

- developing the exposed image and the exposed calibration pattern;
- digitally reading the developed image and the developed calibration pattern and creating digital image data and digital calibration pattern data;
- and
- using the created digital calibration pattern data, correcting the digital image data.
