Abstract
Provided are an apparatus of and method for correcting dust spot position in which a position of a dust spot is detected from an image and corrected in a digital image processing apparatus. The dust spot position correcting apparatus of the digital image processing apparatus includes: a dust sensor sensing dust attached on an imaging device that captures an image; and a digital signal processing unit correcting the sensed dust spot with a color value of the surroundings of a position of the dust spot.
Claims19
A dust spot position correcting apparatus of a digital image processing apparatus, the dust spot correcting apparatus comprising:
- a dust sensor that senses dust attached on an imaging device that captures an image;
- and
- a digital signal processing unit that corrects a position of a spot having sensed dust with a color value of surroundings of the position of the dust.
A dust spot position correcting apparatus of a digital image processing apparatus that recognizes, when noise is generated at a position of an image or at the same position on at least two images, the noise as a dust spot, and corrects a color value of the position of the dust spot with a color value of surroundings of the position of the dust spot.
A method of correcting dust spot position in a digital image processing apparatus, the method comprising:
- (a) sensing dust attached on an imaging device that captures an image, using a dust sensor;
- and
- (b) correcting a color value of the position of the sensed dust spot with a color value of the surroundings of the position of the dust spot.
A method of correcting a position of dust spot, which is an operating method of a digital image processing apparatus, the method comprising:
- (a) recognizing, when noise is generated at the same position on at least two images, the noise as a dust spot;
- and
- (b) correcting a color value of a position of the dust spot with a color value of surroundings of the position of the dust spot.
