Image forming method

A method for processing digital image data to be stored in a storage medium, said digital image data being created by applying a predetermined image-processing to original image data, which are read and converted from a visible pigment image through an image-inputting device after developing said visible pigment image on a silver-halide photosensitive material processed by an image-wise exposing operation, said method comprising the steps of:

• designating a pixel number of said digital image data to be stored in said storage medium;
• retrieving a gradation-setting data set, corresponding to said pixel number designated in said designating step, from a plurality of gradation-setting data sets, each of which corresponds to each of a plurality of pixel numbers established in advance;
• and
• adjusting a gradation characteristic of said digital image data, based on said gradation-setting data set retrieved in said retrieving step.

• designating a combination of an output-gradation number and a pixel number of said digital image data to be stored in said storage medium;
• retrieving a gradation-setting data set, corresponding to said combination of said output-gradation number and said pixel number designated in said designating step, from a plurality of gradation-setting data sets, each of which corresponds to each of combinations of output-gradation numbers and pixel numbers, said combinations being established in advance;
• and
• adjusting a gradation of said digital image data, based on said gradation-setting data set retrieved in said retrieving step.

A method for processing digital image data to be stored in a storage medium, said digital image data being created by applying a predetermined image-processing to original image data, which are read and converted from a visible pigment image through an image-inputting device after developing said visible pigment image on a silver-halide photosensitive material processed by an image-wise exposing operation, said method comprising the steps of:

• storing both said digital image data and said original image data in said storage medium;
• extracting necessary information from said original image data stored in said storage medium;
• and
• applying an image-processing operation, for increasing and/or changing information content of said digital image data on the basis of said necessary information extracted from said original image data, to said digital image data read from said storage medium.

• storing both said digital image data and said original image data in said storage medium;
• creating differential-component data between said digital image data and said original image data, both stored in said storage medium;
• extracting necessary information from said differential-component data created in said creating step;
• and
• applying an image-processing operation, for increasing and/or changing information content of said digital image data on the basis of said necessary information extracted from said original image data, to said digital image data read from said storage medium.

A method for processing digital image data to be stored in a storage medium, said digital image data being created by applying a first predetermined image-processing to original image data, which are read and converted from a visible pigment image through an image-inputting device after developing said visible pigment image on a silver-halide photosensitive material processed by an image-wise exposing operation, said method comprising the steps of:

• storing both said digital image data and sub-original image data in said storage medium, said sub-original image data being created by applying a second predetermined image-processing to said original image data;
• extracting necessary information from said sub-original image data stored in said storage medium;
• and
• applying an image-processing operation, for increasing and/or changing information content of said digital image data on the basis of said necessary information extracted from said original image data, to said digital image data read from said storage medium.
