First USB3 HD video camera


Point Grey, a Canadian developer of digital camera systems has developed the first industrial high definition video camera to use the USB3.0 standard.
It teamed up with Fresco Logic, a fabless semiconductor company that designs, develops and sells USB 3.0 chips for the launch at the 2009 Intel Developer Forum (IDF) in San Francisco. The live demonstration streamed uncompressed High Definition (HD) 1080p60 video from a Point Grey camera, equipped with a high performance Sony HD image sensor, to a USB 3.0 host controller from Fresco Logic on an ASUS P7P55D platform.
The prototype camera is designed and manufactured by Point Grey for the industrial market and uses the new 3 megapixel (MP) Sony IMX036 CMOS image sensor, which features high sensitivity, superior color fidelity, low power, and no smear. The sensor also supports an HD 1080p60 mode, which allows the camera to output raw, uncompressed 1920 x 1080 pixel images at 60 frames per second (FPS). Point Grey’s own software driver provides low-level control of the camera via the USB 3.0 bus. The camera is connected to a USB 3.0 interface card on the host side which is powered by the FL1000, a PCI Express to SuperSpeed USB Extensible Host Controller Interface (xHCI) host controller chip from Fresco Logic. The host PC uses an Intel i5-based P7P55D motherboard from ASUS.
"One of the potential benefits of the increased bandwidth of USB 3.0 is that it allows the main processor to handle compression. This means that different types of compression can be used for different applications and that some applications, like face recognition, can work on uncompressed video data for increased performance. We certainly see USB 3.0 as a key interface technology for machine and computer vision, and one we plan to integrate into future Point Grey imaging products," said said Vlad Tucakov, Director of Sales and Marketing at Point Grey.
