A method is provided for extracting RGB and NW using an RGBW sensor that improves image information processing performance by simultaneously extracting RGB and NIR image information using the RGBW sensor in which pixels of an RGB filter and pixels of a clear filter are coupled, and reducing cost by extracting the NIR image information while not using an infrared cutoff filter is provided. The method includes transmitting, by light, an RGBW filter, and extracting an RGBW image value (R_c, G_c, B_c, W_c) captured by sensing the transmitted light by the RGBW sensor and extracting an RGB value. In addition, the method includes an NIR value by multiplying the captured RGBW image value with an inverse matrix (A) value. |

1. A method for extracting red, green and blue light (RGB) and near infrared light (NW) using a red, green blue, white (RGBW) sensor, the method comprising:
transmitting, by light, an RGBW filter, using a light source; extracting, by a processor, an RGBW image value (R_c, G_c, B_c, W_c) captured by sensing the transmitted light by the RGBW sensor; and extracting, by the processor, an RGB value and an NW value by multiplying the captured RGBW image value with an inverse matrix (A) value. |
