Point Grey Research Inc. has expanded its Firefly MV FireWire digital camera line with the addition of USB 2.0 models. The cameras use the same 1/3-in. CMOS sensor and support 480 Mb/s data transfer rates. They deliver 752 × 480 monochrome or raw Bayer color images at 60 fps, and a 2 × 2 binning mode enables up to 135 fps. Housed in a 44 × 24 × 34-mm plastic case, the cameras include a seven-pin general-purpose input/output connector to synchronize them to external devices.
