Abstract
An image processing apparatus includes an auto document feeder, and can simultaneously scans both sides of an original at a fixed scan position during one-time original feed. The image processing apparatus further includes a first scanning unit that scans a front side of the original in a single-sided scan and a double-sided scan; and a second scanning unit that scans a back side of the original in the double-sided scan. In the double-sided scan, the first scanning unit and the second scanning unit scan the original by using the same scaling method. The first scanning unit uses different scaling methods between the single-sided scan and the double-sided scan based on an original scan condition.
Claims20
An image processing apparatus to scan original documents received via an automatic document feeder in a feed/scan mode, the image processing apparatus comprising:
- an operating unit configured to receive an input;
- a first scanning unit configured to scan a front side of an original document when performing single-sided scanning and when performing double-sided scanning;
- and
- a second scanning unit configured to scan a back side of the original document when performing the double-sided scanning,
- wherein, when performing the double-sided scanning, the front and back sides of the original document are scanned during a single feed of the original document,
- when performing the double-sided scanning, the first scanning unit and the second scanning unit scan the original document based on a first scaling method,
- the first scanning unit uses a second scaling method different from the first scaling method when an original scan condition associated with the original document is satisfied, and
- the first scanning unit uses the first scaling method when the original scan condition associated with the original document is not satisfied.
An image processing method implemented on an image processing apparatus configured to scan original documents received via an automatic document feeder in a feed/scan mode and that includes an operating unit configured to receive an input, a first scanning unit configured to scan a front side of an original document when performing single-sided scanning and when performing double-sided scanning, and a second scanning unit configured to scan a back side of the original document when performing the double-sided scanning, the image processing method comprising:
- performing double-sided scanning of the original document with the first scanning unit and the second scanning unit based on a first scaling method;
- scanning the original document with the first scanning unit using a second scaling method different from the first scaling method when an original scan condition associated with the original document is satisfied;
- and
- scanning the original document with the first scanning unit using the first scaling method when the original scan condition associated with the original document is not satisfied,
- wherein, when performing the double-sided scanning, the front and back sides of the original document are scanned during a single feed of the original document.
