Abstract: A scanner, an image forming apparatus including the same, an image processing method of the scanner and a printing method of the image forming apparatus. The image processing method includes acquiring an environment image, acquiring a main scan image by scanning a document on a flatbed, and extracting a document image from the main scan image using the environment image when the document is scanned with the cover in an open position.

Abstract: A document processing apparatus, including a symbol-related information acquirement unit which identifies a text area in a scanned document, extracts symbols from the identified text area, and acquires symbol-related information regarding each extracted symbol, a symbol division unit which divides the extracted symbols into several groups based on a preset reference value regarding the symbol-related information, and a key index generation unit which generates a key index by arranging one group of symbols from among the divided groups. Accordingly, a user can look for a desired document more easily and conveniently.

Abstract: A sheet of a document is scanned, character objects are extracted from a scan image, the extracted character objects are divided line by line, and the direction of the document is set on the basis of a blank percentage determined according to start and end positions of lines. If the direction of the document is different from that of a previous document, an image processing unit rotates the scan image.

Abstract: An image processing apparatus and a control method thereof. Information of image processing parameters, such as halftoning, edge emphasis, color correction, and gamma correction, is inserted into the document to be printed in the form of the watermark during the printing work. Thus, when the user wants to copy the printed document, the information of the image processing parameters used for printing the document is optimized suitable for the copy by detecting the watermark inserted into the printed document, thereby improving the quality of the copy. The method includes inserting first information of image processing parameters, which are used to print the document, into the document when printing the document, and optimizing second information of image processing parameters to be used for copying the document using the first information of image processing parameters inserted into the document when copying the document.

Abstract: To compensate an image, a profile thereof is obtained from pixel values in a marginal area of the image. A background value of the image determined from the profile and correction to the image is performed in accordance with the background value and the profile.
