Further, the built-in iSight has a plastic lens, is fixed-focus, and uses a CMOS Active pixel sensor, rather than the CCD used in the external iSight. With the LED-Backlit MacBook Pros, Apple has moved to using a sensor capable of 1280x1024 pixels, but when accessed using provided APIs, the image is re-sampled to 640x480 pixels. However, Quartz Composer allows access to the 1280x1024 pixel video stream. The built-in iSight can also be used in the Photo Booth application.
