Abstract:
A method comprising the steps of:a) determining a relative responsivity (S.sub.1) for a pixel of a first color;b) determining a relative responsivity (S.sub.2) for a pixel of a second color;c) determining whether the relative responsivity (S.sub.1) for the first pixel is more than the relative responsivity (S.sub.2) of the second pixel;if yes, forming a mask opening above the first pixel, said mask opening having an area substantially equal to the light receiving area adjusted by a reduction factor, said reduction factor being a result of an arithmetic operation between the relative responsivity of the first pixel and the relative responsivity of the second pixel; and forming a mask opening above the second pixel, said mask opening having an area substantially equal to the light receiving area;else,forming a mask opening above the first pixel, said mask opening having an area substantially equal to the light receiving area; andforming a mask opening above the second pixel, said mask opening having an area substantially equal to the light receiving area adjusted by a reduction factor, said reduction factor being a result of an arithmetic operation between the relative responsivity for a second pixel and the relative responsivity of the first pixel.
