Abstract

PURPOSE:To improve the reproducibility of an intermediate color at a long and short wave region of a green color component, by taking a spectral transmission rate of cyane and yellow filter in the wave length range of 530-570mm. as 0.4-0.6 out of elements of a solid-state image pickup color filter. CONSTITUTION:A filter element group of adjacent two row and two columns is constituted with a magenta transmission filter (Mg), cyane transmission filter (Cy), Yellow transmission filter (Ye), and green transmission filter (G). The maximum value of transmission factor of a blue component of the Cy filter is taken as 0.8 or more, and the transmission rate of green component of 530- 570mm. is taken within the range of 0.4-0.6. In the Ye filter, the maximum value of the transmission rate of red component is taken as 0.8 or more and the transmission rate of green component is taken within 0.4-0.6.
