Auto-focus image sensor and digital image processing device having the sensor

The present invention provides a digital image processing apparatus including an image sensor and automatic focus it. The auto focus image sensor substrate comprising at least one second pixel are used to detect at least one of the first pixel with the image that is used to detect the phase difference; Deep element isolation portion that is disposed in the substrate separating the second pixel and the first pixel; And at least it disposed on the substrate in the first pixel, and includes a light-shielding pattern to control the amount of light so that the small quantity of light than the amount of light incident on the second incident pixel.
