Abstract
An image scanning apparatus and method are provided. The image scanning apparatus includes a scanner that scans a manuscript to generate a scan image, an image processor that calculates a manuscript boundary on the generated scan image as an equation and compensates a distortion of the scan image using the calculated equation, and a storage member that stores the scan image of which the distortion has been compensated.
Claims24
An image scanning apparatus comprising:
- a scanner that scans a manuscript and generates a scan image;
- an image processor that calculates a manuscript boundary on the generated scan image as an equation, and compensates a distortion of the scan image using the calculated equation;
- and
- a storage member that stores the scan image of which its distortion has been compensated.
An image scanning apparatus comprising:
- a scanner that scans a manuscript in a predetermined first resolution to generate a first scan image;
- an image processor that calculates a manuscript boundary on the generated first scan image as an equation;
- a controller that controls the scanner to scan the manuscript in a second resolution that is higher than the first resolution to generate a second scan image, and controls the image processor so that a distortion of the second scan image is compensated using the equation calculated through the first scan image;
- and
- a storage member that stores the second scan image of which the distortion has been compensated.
An image compensation method of an image scanning apparatus, the method comprising:
- scanning a manuscript to generate a scan image;
- calculating a manuscript boundary on the generated scan image as an equation;
- and
- compensating the distortion of the scan image using the calculated equation.
An image compensation method of an image scanning apparatus, the method comprising:
- scanning a manuscript in a predetermined first resolution to generate a first scan image;
- calculating a manuscript boundary on the generated first scan image as an equation;
- scanning the manuscript in a second resolution that is higher than the first resolution to generate a second scan image;
- compensating a distortion of the second san image using the equation calculated through the first scan image;
- and
- storing the second scan image of which the distortion has been compensated.
