Abstract:
1. A solid state image pickup device comprising: a semiconductor substrate having a light receiving area; a number of pixels formed in the light receiving area of said semiconductor substrate in a matrix shape of rows and columns, each of said pixels having a main photosensitive field having a relatively large area and a subsidiary photosensitive field having a relatively small area; a vertical charge transfer path formed in said semiconductor substrate along each column of said pixels, capable of reading an image signal from either one of the main photosensitive field and the subsidiary photosensitive field of associated pixels; a main color filter array formed above said semiconductor substrate and covering at least said main photosensitive fields in register with said respective pixels; and a micro lens array formed above said color filter array, one for each of said pixels and covering at least the associated main photosensitive field, wherein the number of vertical charge transfer paths is one for each column of pixels.
