Image acquiring device and method or rotating images

Abstract

An image acquiring device and method of rotating images includes a scanning module, a driving mechanism, a selecting module, a control-processing unit and a memory. The scanning module scans a plurality of originals in sequence in conjunction with the driving mechanism. The selecting module selects a specific mark of a first original as a basis for judging an orientation state of a second original. The control-processing unit generates a digital mark signal stored in the memory according to the signals output from the scanning module and the selecting module. The control-processing unit judges a position of the digital mark signal in a digital signal obtained after the second original is scanned, and thus generates a rotating signal and rotates the digital signal into a normal image signal according to the rotating signal. Thus, the document image may be automatically rotated into a normal state.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The invention relates to an image acquiring device and an image acquiring method of rotating images, and more particularly to an image acquiring device and an image acquiring method enabling a user to select a specific mark of an original as a basis for image rotation. [0003] 2. Description of the Related Art [0004] In the prior art, the scanned image has to be transferred to a computer and processed by the application software so that the image can be rotated by 180 degrees. Typically, the user views the scanned image and determines whether the image has to be rotated or how the image has to be rotated, or an OCR (Optical Character Recognition) method using specific OCR software can be used to determine the rotation angle, as disclosed in U.S. Pat. Nos. 6,011,877, 6,546,215, and 6,574,375. Alternatively, the conventional copier provides the user the function of selecting the orientation of the image of the to-be-co...

AI Technical Summary

Benefits of technology

The invention provides an image acquiring device that can automatically rotate images based on their orientation, making it easier to process and use them. This is achieved by scanning multiple originals, selecting a specific mark on the first one, and using the information from the scanning and selecting modules to generate a rotating signal that can be applied to the second original. This simplifies the process of judging the document orientation and ensures that the image is rotated correctly. The rotated image can then be outputted to an image processing device for further processing.

Problems solved by technology

In this case, it is very inconvenient to manually rotate the images using the application software on the computer or using the image rotating method on the copier.

Using the OCR method to process the stack of documents requires a relatively large memory and the documents only having pictures as contents cannot be recognized.
