Abstract
An image sensor for an image processing apparatus having a color filter array with open window cells alternating with single color filter cells includes a lens array containing a plurality of microlenses, a color filter array having a plurality of open window cells and color filter cells, each corresponding to one microlens. The image sensor also includes a protection layer, and a pixel sensor array having a first photosensor sensing a first light passed through each color filter cell, a second photosensor formed under the first photosensor, sensing a second light passed through each color filter cell, a third photosensor sensing a third light passed through each open window cell, and a fourth photosensor formed under the third photosensor, sensing a fourth light passed through each open window cell.
