Noise insensitive high resolution color interpolation method for considering cross-channel correlation

摘要

The present invention relates to a high-resolution color interpolation method based on correlation between the strongest channels in the noise. ; The invention CCD (Charge Coupled Device) surface in CFA (Color Filter Array) a by coating the pixel in accordance with R (red), G (green), B (blue) of the optional to a value obtained after the lack of two-channel value in the color interpolation method of the CCD used to interpolate the value of the nearby pixels is a first process in consideration of the noise performs interpolation of the G channel and the noise in the position B channel interpolation and B considering the noise in the R position performing the R channel interpolation considering the second process comprises a third step for calculating an interpolated image for the R channel and B channel considering the noise from the G position. ; According to the present invention, so removing noise in consideration of the correlation between the channels and interpolation the value of the lost color channel has an effect capable of removing the errors visible. ; Noise, color, color channel, interpolation, correlation, CCD, CIS, edge
