Abstract:
1. An image processing method adapted to correct the luminance of green pixels in a Bayer pattern, comprising: generating a low-pass weight according to a luminance difference average between a predetermined green pixel and a plurality of green pixels, a first predetermined luminance and a second predetermined luminance by a content adaptive unit; generating a de-noise value according to a luminance weighted average of a plurality of green pixels by a de-noise filter unit; generating a first color weighted value according to the low-pass weight and a luminance weighted average of the plurality of green pixels within the first color area, generating a second color weighted value according to the low-pass weight and a luminance weighted average of the plurality of green pixels within the second color area, and generating a color weighted difference according to the first color weighted value and the second color weighted value by a color weighted calculation unit; generating a mixed luminance value according to the low-pass weight, the de-noise value and the luminance of the predetermined green pixel by a mix unit; and generating a luminance corrected value according to the mixed luminance value, a first luminance average, a second luminance average, the color weighted difference and a control parameter by a compensation unit.
