Solid-state color image pickup device for reproducing a color image

A solid-state color image pickup device comprising:

• a substrate;
• a plurality of light-receiving picture elements arranged in a matrix on a surface of said substrate;
• and
• a color filter disposed to cover said plurality of light-receiving picture elements, wherein said color filter is divided into a plurality of units of color component regions arranged in a plurality of rows, each unit including three different color component regions arranged in a row in each of said plurality of rows in correspondence with two adjacent light-receiving picture elements, wherein a middle one of said three different color component regions is disposed over portions of both of said two adjacent light-receiving picture elements, and a position of each color component region in an odd-numbered row is shifted in a direction of said row of the color filter from a position of each color component region in an even-numbered row by one color component region.

• a first filter element and a second filter element for passing light having a first color component and light having a second color component, respectively, are disposed in odd-numbered rows;
• a third filter element and a fourth filter element for passing light having a third color component and light having a fourth color component, respectively, are disposed in even-numbered rows;
• and said filter elements pass light having color components which satisfies the following conditions:
• a sum of a light-receiving signal obtained from a light-receiving picture element which corresponds to said first filter element on the basis of said light having said first color component and a light-receiving signal obtained from a light-receiving picture element which corresponds to said second filter element on the basis of said light having said second color component is equal to a sum of a light-receiving signal obtained from a light-receiving picture element which corresponds to said third filter element on the basis of said light having said third color component and a light-receiving signal obtained from a light-receiving picture element which corresponds to said fourth filter element on the basis of said light having said fourth color component;
• a light-receiving signal of a first fundamental color component is obtained from a difference between said light-receiving signal based on said light having said first color component and said light-receiving signal based on said light having said second color component;
• and
• a light-receiving signal of a second fundamental color component is obtained from a difference between said light-receiving signal based on said light having said third color component and said light-receiving signal based on said light having said fourth color component.
