Abstract

First image information recorded on a first subject copy is read for establishing processing conditions, and processing conditions are established based on the first image information which has been read. At the same time that the processing conditions are established based on the first image information, second image information recorded on a second subject copy is read for establishing processing conditions. The first image information recorded on the first subject copy is read again according to the established processing conditions to obtain output image information to be reproduced. Alternatively, processing conditions are established based on the second image information that has been read, at the same time that the first image information recorded on the first subject copy is read according to the established processing conditions.

Claims

1. A method of reading an image from a subject copy, comprising the steps of:

providing an image reading apparatus for preliminarily scanning image information recorded on a first subject copy for determining a first set of image processing conditions;

establishing said first set of image processing conditions in said image reading apparatus;

causing said image reading apparatus to preliminarily scan image information recorded on a second subject copy for determining a second set of image processing conditions, at the same time that said first set of image processing conditions are being established in said image reading apparatus; and

reading said image information recorded on said first subject copy according to said first set of image processing conditions to obtain output image information to be reproduced.

2. A method of reading an image from a subject copy, comprising the steps of:

providing an image reading apparatus for preliminarily scanning image information recorded on a first subject copy for determining a first set of image processing conditions;

establishing said first set of image processing conditions in said image reading apparatus;

causing said image reading apparatus to preliminarily scan image information recorded on a second subject copy for determining a second set of image processing conditions;

reading said image information recorded on said first subject copy according to said first set of image processing conditions to obtain output image information to be reproduced; and

establishing said second set of image processing conditions in said image reading apparatus, at the same time that said image information recorded on said first subject copy is read according to said first set of image processing conditions to obtain said output image information.

3. An apparatus for reading an image from a subject copy, comprising:

scanning reading means for reading image information recorded on a subject copy;

setting means for establishing image processing conditions with respect to said image information;

control means for controlling said scanning reading means to read said image information from said subject copy for determining said image processing conditions, controlling said setting means to establish said image processing conditions based on said image information that has been read, and controlling said scanning reading means to read output image information to be reproduced from said subject copy according to said image processing conditions, said control means comprising means for simultaneously controlling said scanning reading means to read said image information and said setting means to establish said image processing conditions or simultaneously controlling said setting means to establish said image processing conditions and said scanning reading means to read said output image information; and

memory means for storing said image processing conditions, and said image information for establishing said image processing conditions.

4. An apparatus according to claim 3, wherein said scanning reading means comprises an auxiliary scanning mechanism for feeding a copy cassette holding a plurality of subject copies in an auxiliary scanning direction, and an image reader for optically scanning said subject copies held by said copy cassette in a main scanning direction substantially normal to said auxiliary scanning direction, to obtain said image information.

5. An apparatus according to claim 3, wherein said setting means comprises an input unit for entering said image processing conditions, and a display unit for displaying said image processing conditions which are entered through said input unit.

6. An apparatus according to claim 5, wherein said display unit comprises means for displaying a cassette display area which indicates processing status of a copy cassette holding said subject copies, a copy display area which indicates a subject copy being processed in said copy cassette, and a setup display area which indicates processing status of said subject copies.
