BC Tech out of Santa Cruz, CA has released a tiny video camera targeted at integration into small, and even disposable, endoscopic devices for high quality image transmission.
At only 3 millimeters in diameter and featuring four LED’s for lighting the scene, the camera has a 400 x 400 resolution CCD streaming at 30 frames a second. Perhaps this camera can be embedded into a cable that plugs into a device like an iPhone to make an endoscope straight out of Star Trek.
