Although external and internal iSights have significant differences, Apple has used the "iSight" name to brand its built-in video camera found in their MacBook, MacBook Air and MacBook Pro notebook computers, iMac desktop computers produced since late 2005 and the LED Cinema Display. While the external iSight is similar to the built-in iSight, the built-in iSight uses an internal USB 2.0 interface and not the FireWire 400 (IEEE 1394a) interface used by the external iSight camera. 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.
