[0002]

2. Description of the Related Art When an original is read and recorded and scanned using an image processing apparatus such as a plate making scanner, a representative portion of the original is reproduced so that the original is reproduced in a desired state.
For example, setup conditions for a highlight point, a shadow point, a tone curve, and the like are set in advance.

However, during the operation of setting up the setup conditions in the image processing apparatus, the reading and recording scanning of the original cannot be performed, so that the operation rate of the image processing apparatus is reduced, and the image processing cannot be performed efficiently. . Therefore, for the purpose of improving the driving rate of the image processing apparatus, a setup apparatus that determines only the setup conditions of the image processing apparatus in a separate process has been devised. The set-up conditions determined by this type of device are set up by manually entering the set-up conditions in a table by item, punching out on a computer output form, or storing in a magnetic storage medium such as a floppy disk. The original is paired and brought to the image processing device, and the setup conditions are set on the image processing device by manual input by operating the dial or key of the image processing device or by reading data from the magnetic storage medium. Then, scanning input of the document is performed.

[0005]

Conventionally, the use form of the set-up device is as described above, and the set-up conditions determined therefrom are determined by using a magnetic storage medium such as paper or a floppy disk to copy the original. I managed it as a set. In such a case, handling was troublesome, such as placing the set-up conditions and the original in the same vinyl case so as not to separate the pair. In addition, since the setup condition is transmitted to the scanner via another medium, that is, a so-called off-line connection, there is a loss in the time required to fill in the special paper and the time required for medium exchange, which is inefficient.

When an image processing apparatus is used in combination with two or more setup apparatuses, when data is transferred off-line, there are a plurality of magnetic disks storing setup conditions, so that the exchange operation is complicated. there were. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an image processing system that can easily input and output a setup condition and improve an operation rate of an image processing apparatus. .
