![]() It seems that this represents the superimposition of lower bandwidth chrominance information onto the luminance data. In colour mode the same amount of data is transmitted but now the intensities of the pixels in the image vary in a repeating 2x2 pattern. Image recovery is simply a question of scaling the resulting image to restore the original aspect ratio (few if any of the camera's modes seem to have naturally square pixels). These bytes are transmitted in left to right, top to bottom order. This is what we know about the camera's data format so far: In monochrome mode the 3Com HomeConnect Webcam returns image data as a stream of bytes that represent the luminance of pixels that form the image. His page detailing his investigations is here. Unfortunately neither 3Com or Vista Imaging who designed the camera have released any technical information to allow a driver to be written believing that their commercial interests could be damaged if this information were to become public, so we're on our own with this one.Īrmed with USB Snoopy, John T Willis has successfully captured conversations between the driver and the camera. ![]() The 3Com HomeConnect (3CO3C886) is a good quality USB camera which, as standard, is supplied with Windows and Macintosh drivers but, regrettably, none for Linux. ![]() HomeConnect USB Driver for Linux HomeConnect USB Driver for Linux
