Integrated Camera

The Integrated camera

Almost all recent ThinkPads have an integrated camera above the display. This camera (typically called a webcam) is USB attached. On some earlier ThinkPads a proprietary camera was used, but later models use a standard UVC camera which is supported by the uvcvideo driver.

Because of their location above the display the cameras all share a long and thin board layout. But the exact shape varies. Often several models share the exact same form factor, but with different resolutions. DIY upgraders can sometimes use higher resolution cameras from later models or cheaper camera modules from earlier’s.

Also their connector varies.

ThinkPads which may have a proprietary camera

These ThinkPads have a 0.3MP fixed focus Sonix SN9C201 camera which is supported by the gspca_sn9c20x driver.
