Abstract
An apparatus for correcting an image includes an image scanning unit, including a light source, that emits a beam generated by the light source toward a document, and scans an image of the document formed by a beam reflected from the document to obtain a scanned image; a beam brightness sensing unit that senses a brightness of the beam generated by the light source; and a correction output unit that corrects the scanned image according to the brightness of the sensed beam sensed by the beam brightness sensing unit to obtain a corrected image, and prints the corrected image.
Claims20
An apparatus for correcting an image, the apparatus comprising:
- an image scanning unit, comprising a light source, that emits a beam generated by the light source toward a document, and scans an image of the document formed by a beam reflected from the document to obtain a scanned image;
- a beam brightness sensing unit that senses a brightness of the beam generated by the light source;
- and
- a correction output unit that corrects the scanned image according to the brightness of the beam sensed by the beam brightness sensing unit to obtain a corrected image, and prints the corrected image.
A method of correcting an image, comprising:
- emitting a beam generated by a light source toward a document, and scanning an image of the document formed by a beam reflected from the document to obtain a scanned image;
- sensing a brightness of the beam generated by the light source;
- and
- correcting the scanned image according to the brightness of the beam sensed in the sensing of the brightness to obtain a corrected image, and printing the corrected image.
An apparatus for correcting an image, the apparatus comprising:
- an image scanning, unit comprising a light source, that emits a beam generated by the light source toward a document, and scans an image of the document formed by a beam reflected from the document to obtain a scanned image;
- a beam brightness sensing unit that senses a brightness of the beam generated by the light source;
- an image correcting unit that corrects a shading level of the scanned image to a predetermined reference level according to the brightness of the beam sensed by the beam brightness sensing unit to obtain a corrected image;
- and
- an image storage unit that stores the corrected image.
A method of correcting an image, the method comprising:
- emitting a beam generated by a light source toward a document, and scanning an image of the document formed by a beam reflected from the document to obtain a scanned image;
- sensing a brightness of the beam generated by the light source;
- correcting a shading level of the scanned image according to the brightness of the beam sensed in the sensing of the brightness to obtain a corrected image;
- and
- storing the corrected image.
An apparatus for correcting an image, the apparatus comprising:
- an image scanning unit that scans an image of a document to obtain a scanned image in which an image characteristic depends on how long an element of the apparatus has been turned on;
- and
- a correction output unit that corrects the scanned image to obtain a corrected image in which the image characteristic does not depend on how long the element of the apparatus has been turned on.
