By using a memory capable of storing image data of a document size smaller than a maximum document size, images on both sides of a document of the maximum document size can be simultaneously read.
Claims5
An image processing apparatus comprising:
- a reader;
- and
- a controller,
- wherein the reader comprises:
- a conveying unit configured to convey a plurality of documents of different sizes;
- a reading unit configured to read an image of a document conveyed by the conveying unit;
- a detecting unit configured to detect a size of a document conveyed by the conveying unit;
- a notifying unit configured to notify the controller of a document size detected by the detecting unit;
- and
- a transmitting unit configured to transmit a document image read by the reading unit to the controller,
- wherein the controller comprises:
- a setting unit configured to set an image magnification ratio in accordance with a document size notified by the notifying unit;
- and
- a changing unit configured to change magnification of an image transmitted by the transmitting unit, in accordance with a magnification ratio set by the setting unit, and
- wherein, before the detecting unit detects the document size, the notifying unit notifies the controller of a tentative document size, and when the detecting unit detects the document size, the notifying unit notifies the controller of the document size detected by the detecting unit.

A control method for controlling an image processing apparatus comprising a reader and a controller,
- wherein the reader comprises:
- conveying a plurality of documents of different sizes;
- reading images of the conveyed documents;
- detecting sizes of the conveyed documents;
- notifying the controller of the detected document sizes;
- and
- transmitting the read document images to the controller,
- wherein the controller comprises:
- setting an image magnification ratio in accordance with a document size notified by the reader;
- and
- changing magnification of an image transmitted by the reader, in accordance with the set magnification ratio, and
- wherein, before the document size is detected, the reader notifies the controller of a tentative document size, and when the document size is detected, the reader notifies the controller of the detected document size.

A non-transitory computer readable storage medium for storing a computer program for controlling an image processing apparatus including a reader and a controller,
- wherein the reader comprises:
- a code to read an image of a document conveyed by a conveying unit conveying a plurality of documents of different sizes;
- a code to detect a size of the conveyed document;
- a code to notify the controller of the detected document size;
- and
- a code to transmit the read document image to the controller, and
- wherein the controller comprises:
- a code to set an image magnification ratio in accordance with a document size notified by the reader;
- and
- a code to change magnification of an image transmitted from the reader, in accordance with the set magnification ratio, and
- wherein, before the document size is detected, the reader notifies the controller of a tentative document size, and when the document size is detected, the reader notifies the controller of the detected document size.
