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.

ThinkPads which may have a UVC camera

The video interface controllers recorded here so far are:

  • Xenon or Xinon or sth.
  • Ricoh R5U875: VGA (640×480 0.3MP) @30fps and both SXGA (1280×1024 1.3MP), UXGA (1600×1200 1.9MP) @15fps
  • Ricoh R5U877: VGA (640×480 0.3MP), UXGA (1600×1200 1.9MP) @30fps and QXGA (2048×1536 3.1MP) @15fps. Has an Image Signal Processor.
 * USB id: 17ef:480d (Lenovo Integrated Webcam [R5U877])
 * referred to as 2.0MP camera

0.3MP fixed focus

1.3MP fixed focus

Ricoh R5U875 video interface controller supporting VGA (640×480 0.3MP) @30fps and both SXGA (1280×1024 1.3MP), UXGA (1600×1200 1.9MP) @15fps

2.0MP fixed focus

USB ID: 17ef:480d (Lenovo Integrated Webcam [R5U877] The Ricoh R5U877 video interface controller supports VGA (640×480 0.3MP), UXGA (1600×1200 1.9MP) @30fps and QXGA (2048×1536 3.1MP) @15fps. In contrast to the R5U875 it has an integrated Image Signal Processing unit.
