| description | A method for processing images acquired by a multispectral RGB-NIR (red/green/blue/near-infrared) sensor according to an aspect of the technical concept of the present disclosure comprises the steps of: receiving an RGB-NIR digital image, which includes red (R), green (G), blue (B), and NIR pixels, from a multispectral RGB-NIR sensor; interpolating the NIR contributions to each of the R, G, and B pixel values to acquire a NIR image; subtracting the NIR contributions from each of the R, G, and B pixel values of the RGB-NIR digital image to acquire a noise-reduced RGB-NIR image; constructing a red, green, and blue (RGB) Bayer image from the noise-reduced RGB-NIR image; and acquiring a full-color image through processing the Bayer image. The even rows or odd rows of the RGB-NIR digital image may include NIR pixels alternating with green pixels, and the remaining rows of the RGB-NIR digital image may include green pixels alternating with red and blue pixels. Thus, the method for processing images can provide a calibration process calculating noise factors.
