The present invention provides a method for extracting RGB and NIR by using a RGBW sensor, wherein the RGBW sensor formed by combining pixels of an RGB filter with pixels of a Clear filter is used to simultaneously extract image information on both RGB and NIR, thereby improving image data processing performance, and image information on NIR can be extracted without using an infrared cut-off filter, thereby saving costs. The method for extracting RGB and NIR by using a RGBW sensor according to an embodiment of the present invention comprises the following steps of: light penetrating an RGBW filter; the penetrated light being sensed by an RGBW sensor to extract values of the captured RGBW image (R_c, G_c, B_c, W_c); and the values of the captured RGBW image being multiplied by values of a inverse matrix (A) to extract an RGB value and an NIR value. |
