PURPOSE: A unit pixel for a CFA(Color Filter Array) in an image sensor is provided to improve S/N(Signal to Noise) ratio and increase dynamic range by arranging a white light pass pattern in the CFA. CONSTITUTION: A unit pixel(100) for color filter having red(R), green(G) and blue(B) color pixel is arranged in a color filter array. The unit pixel(100) is provided with a white light pass pattern(200). The white light pass pattern(200) is formed in each color pixel of red(R), green(G) and blue(B), respectively. Each unit pixel(100) is provided with two green color pixels(G) having the same area, a red color pixel(R) and a blue color pixel(B).
