Image processing method and apparatus for Bayer images

摘要

Provided are a method and apparatus for processing Bayer images. The Bayer image processing method including interpolating red (R), green (G), and blue (B) image signals output in Bayer patterns; converting the interpolated RGB image signals to a luminance signal and chrominance signals; correcting phases of the chrominance signals based on the luminance signal; and removing aliasing of the luminance signal and aliasing of the phase-corrected chrominance signals.

1. A Bayer image processing method comprising:
interpolating red (R), green (G), and blue (B) image signals output in Bayer patterns; converting the interpolated RGB image signals to a luminance signal and chrominance signals; correcting phases of the chrominance signals based on the luminance signal, wherein the correcting of the chrominance signals is performed at pixel positions at which pixel values of the luminance signal are rapidly changing and comprises:
calculating positions where the phases of the luminance signal and the chrominance signals do not match with each other; andcorrecting the chrominance signals at the calculated positions; and removing aliasing of the luminance signal and aliasing of the phase-corrected chrominance signals.
