Abstract
A method of scanning a document to generate image data of the document, the method including performing a pre-scanning operation at a first predetermined resolution and speed according to a scan command until a current scanning area is located in a main-scan area; and performing a main-scanning operation at a second predetermined resolution and speed, until the current scanning area is beyond the main-scan area, after the current scanning area has been located in the main-scan area.
Claims14
A method of scanning a document to generate image data of the document using a multi-functional peripheral device by scanning at least one document, the method comprising:
- inputting a scan start command through a manipulator of the multi-functional peripheral device for the at least one document;
- performing a pre-scanning operation at a first predetermined resolution and speed until a current scanning area is located in a starting location of a first main-scan area;
- stopping the pre-scanning operation when the current scanning area is located in the starting location of the first main-scan area;
- and
- starting a main-scanning operation at a second predetermined resolution and speed from the starting location of the first main-scan area:
- performing the main-scanning operation until the current scanning area is located in an ending location of the first main-scan area;
- and
- performing the pre-scanning operation until the current scanning area is located in an ending location of a physical scan area of the multi-functional peripheral device or a starting location of a second main-scan area, when the current scanning area is beyond the ending location of the first main-scan area,
- wherein the pre-scanning operation and the main-scanning operation are performed according to the one-time scan start command, and the ending location of the physical scan area is determined by using white data.

A method of scanning documents to generate image data of the document using a multi-functional peripheral device by scanning one or more documents, the method comprising:
- placing one or more documents to be scanned within a physical scan area;
- in putting a scan start command through a manipulator of the multi-functional peripheral device for the documents placed on the physical scan area;
- performing a pre-scanning operation at a first predetermined resolution and speed until a current scanning area is located in a starting location of a main-scan area of a first document of the documents;
- stopping the pre-scanning operation when the current scanning area is located at the starting location of the main-scan area of the first document;
- starting a main-scanning operation at a second predetermined resolution and speed from the starting location of the main-scan area of the first document;
- performing the main-scanning operation until the current scanning area is located in an ending location of the main-scan area of the first of the document;
- and
- after performing the main-scanning operation until the ending location of the main-scan area of the first document, sequentially repeating the performing the pre-scanning operation, the stopping the pre-scanning operation, and the performing the main-scanning operation on the remaining documents of the documents until the current scanning area is located in the physical scan area,
- wherein the performing the pre-scanning operation, the stopping the pre-scanning operation, the starting the main-scanning operation, the performing the main-scanning operation, and the sequentially repeating are performed according to the one-time scan start command, and the ending location of the physical scan area is determined by using white data.
6 more elements
A multi-functional peripheral device for scanning a document, the multi-functional peripheral device comprising:
- one or more documents placed on a physical scan area of the multi-functional peripheral device;
- a manipulator for inputting a scan start command for the documents placed on the physical scan area;
- a scanner comprising an optical system for outputting an electric signal by photoelectric transforming density of the documents placed on the physical scan area according to the scan start command, and an image processor for converting the electric signal output from the optical system into digital image data;
- a controller controlling the scanner so as to perform a pre-scanning operation at a first predetermined resolution and speed until a current scanning area is located in a starting location of a first main-scan area, stop the pre-scanning operation when the current scanning area is located in the starting location of the first main-scan area, start a main-scanning operation at a second predetermined resolution and speed from the starting location of the first main-scan area, perform the main-scanning operation until the current scanning area is located in an ending location of the first main-scan area, and perform the pre-scanning operation until the current scanning area is located in an ending location of a physical scan area of the multi-functional peripheral device or a starting location of a second main-scan area, when the current scanning area is beyond the ending location of the first main-scan area,
- wherein the pre-scanning operation and the main-scanning operation are performed according to the one-time scan start command, and the ending location of the physical scan area is determined by using white area.
