Problems solved by technology

However, this scanning method cannot compensate for errors that occur during the addition of the fiducial marks 53 to the scanner 20, and requires separate equipment and processing to accurately add the fiducial marks 53, which increases the cost required to manufacture the scanner.
In addition, since the fiducial mark 53 is located outside the effective scanning area, it will be difficult to accurately compensate the image data obtained from the actual scanning

Embodiment Construction

[0027] Reference will now be made in detail to embodiments of the invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout. The embodiments are described below in order to explain the present invention by referring to the figures.

[0028] Figure 4A and Figure 4B The concept of the scanning method according to the embodiment of the present invention is schematically illustrated.

[0029] first, Figure 4A Illustrated is a concept of a scanner 200 that scans a reference paper sample (not shown) having a predetermined pattern, calculates a compensation value based on the scanning result, and transmits the calculated compensation value to the scanner installed in the computer system 100. instrument driver (not shown), and update the driver. When the updated driver is used to drive the scanner 200 , the computer system 100 can preemptively compensate the coordinate values ​​of the scanning ar...

Abstract

An image data compensation method and apparatus, with the method including calculating a distance between a first reference line adjacent to a pattern and the pattern, calculating a distance between a second reference line adjacent to the pattern and perpendicular to the first reference line and the pattern, and calculating a difference between the predetermined coordinate value and the distances calculated, based on the first and second reference lines. Such an image data compensation method can compensate for image data errors due to mechanical tolerances each scanner has at a low cost when the scanner scans documents.

Description

technical field [0001] The invention relates to a scanner, in particular to an image data compensation method of the scanner capable of improving scanning accuracy at low cost. Background technique [0002] Typically, a scanner (such as an optical scanner) emits light onto a medium, such as a paper document, and reflects it from the medium, where it is captured by a sensor such as a charge-coupled device (CCD) or a contact image sensor (CIS). The reflected light is converted into an electrical signal, and the electrical signal is stored in a storage medium such as a hard disk drive (HDD) in the computer system. Typically, a scanner has a platform on which a document can be placed, and an optical mechanism that emits light onto the document placed on the flatbed. The optical mechanism is designed to move back and forth while projecting light onto an area corresponding to the size of the document so as to project light onto the entire document area. [0003] figure 1 A conv...
