Patent ID: 8582874

Claim:
A color interpolation apparatus, comprising: a color interpolation unit, performing an interpolation of an inputted Bayer pattern image and generating first output data and second output data, detecting first edge component data and second edge component data corresponding to the inputted Bayer pattern image, and detecting a difference between a maximum value and a minimum value of elements of the second edge component data; a first determining unit, determining an output according to the difference from the color interpolation unit, and determining an edge enhancement coefficient by using the first and second edge component data and an edge parameter; a second determining unit, determining a maximum value and a minimum value of elements of the output of the first determining unit; and a removing unit, determining a noise removing method of image data of the inputted Bayer pattern image according to the difference, received from the color interpolation unit, and the maximum value and the minimum value, received from the second determining unit, and performing the corresponding noise removing.
