ABSTRACT:
A solid state image pickup device having: a semiconductor substrate having a light receiving area; a number of pixels formed in the light receiving area of the semiconductor substrate in a matrix shape, each of the pixels having a main photosensitive field having a relatively large area and a subsidiary photosensitive field having a relatively small area; a main color filter array formed above the semiconductor substrate and covering at least the main photosensitive fields in register with the respective pixels; and a micro lens array formed on the color filter array and covering at least the main photosensitive fields in register with the respective pixels, wherein an image signal can be selectively picked up from either one of the main and subsidiary photosensitive fields. A solid state image pickup device having a high resolution can be provided.
