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.

Embodiment Construction

[0016]FIG. 1 shows a first original and a second original to be scanned by an image acquiring device of the invention. FIG. 2 is a block diagram showing an image acquiring device according to a first embodiment of the invention. Referring to FIGS. 1 and 2, the image acquiring device 10 of the invention includes a scanning module 12, a driving mechanism 14, a selecting module 16, a control-processing unit 18 and a memory 20. The scanning module 12 sequentially scans a first original D1 and a second original D2 to generate a first analog signal SA1 and a second analog signal SA2 respectively. Each original has a specific mark M at a specific position P. Usually, the specific mark M is located at one of the four long rectangles depicted by dashed lines of FIG. 1. In this embodiment, the two originals are illustrated as an example and the invention is not limited thereto. When the number of the originals is greater than 2, the originals after the second original are processed in the sam...

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...
