摘要： An image processing method and an image processing apparatus for removing noise from an image are disclosed. A provided image processing method includes: dividing an input image into a luminance signal and a chrominance signal; removing noise from the luminance signal; restoring luminance signal present in the noise removed from the luminance signal; removing noise from the chrominance signal; and combining the luminance signal and the chrominance signal from which the noises are removed. Accordingly, an image of which an edge component is well preserved and a degree of color noise is low is generated not only in a general environment but also in a low light level and high sensitivity environment having a large amount of noise.

摘要： A digital image processing apparatus has a tracking function for tracking a location variation of a set tracking area on a plurality of frame images. The digital image processing apparatus includes a similarity calculation unit that calculates a similarity by varying a location of a template on one frame image. The similarity calculation unit calculates a second direction similarity by fixing a first direction location of the template in a first direction on the one frame image and by varying a second direction location of the template in a second direction which is perpendicular to the first direction, and then calculates a first direction similarity by fixing the second direction location of the template at a location where the second direction similarity is the highest and by varying the first direction location of the template in the first direction on the one frame image.
