Image processing apparatus having a reader movable to a designated position

An image processing apparatus comprising:

• reader means for reading an image and generating image data accordance therewith;
• first moving means for moving a reading position of said reader means in a main scanning direction;
• second moving means for moving the reading position of said reader means in a sub-scanning direction;
• setting means for setting a desired operation mode;
• recognizing means for recognizing a coordinate of the reading position of said reader means;
• designating means for designating movement of the reading position of said reader means to a desired position;
• control means for controlling said first and second moving means to cause, if a first mode has been set by said setting means, the reading position of said reader means to be moved a plurality of times in the main scanning direction, and also to be moved in the sub-scanning direction every time the reading position is moved in the main scanning direction so that said reader means can read the image to be and to cause, if a second mode has been set by said setting means, the reading position of said reader means to be moved to the desired position in accordance with the designation of said designating means, so that said recognizing means can recognize the coordinate of the reading position of said reader means;
• and
• discriminating means for discriminating one of (1) a size and (2) a position of an image read by said reader means in the first mode based on the coordinate recognized by said recognizing means in the second mode.

An image processing apparatus comprising:

• reader means for reading an image and generating image data corresponding thereto;
• first moving means for moving a reading position of said reader means in a main scanning direction;
• second moving means for moving the reading position of said reader means in a sub-scanning direction;
• setting means for setting a desired operation mode;
• designating means for designating movement of the reading position of said reader means to a desired position;
• control means for controlling said first and second moving means to cause, if a first mode has been set by said setting means, the reading position of said reader means to be moved a plurality of times in the main scanning direction, and also to be moved in the sub-scanning direction every time the reading position is moved in the main scanning direction, so that said reader means can read all over the area of the image, and to cause, if a second mode has been set by said setting means, the reading position of said reader means to be moved to the desired position in accordance with the designation of said designating means, so that said reader means can read the image at the desired position;
• and
• recognizing means for recognizing color balance information of a color image of the image at the desired position based on image data generated by said reader means in the second mode.

• and
• recognizing means for recognizing an image density of a monochromatic image, of the image at the desired position based on image data generated by said reader means in the second mode.
