PURPOSE: An image sensor and an image processing system are provided to efficiently perform automatic dark level compensation. CONSTITUTION: A first optical black pixel generates a first optical black signal by blocking light using a black filter. A second optical black pixel generates a second optical black signal by blocking the illuminance of the light which is lower than reference illuminance. A third optical black pixel(910) generates a third optical signal by blocking the illuminance of the light which is higher than the reference illuminance. The third optical black pixel includes a micro lens(911), a light blocking device, an insulating layer(913), metal(914), a unit pixel circuit area(916), and a substrate(618).
