Typical one-chip color cameras use analog video processing circuits. An improved digital camera architecture has been developed using a dual-slope AID conversion technique and two full-custom CMOS digital video processing integrated circuits, the color filter array (CFA) processor and the ROB postprocessor. The system uses a 768 x 484 active element interline transfer CCD with a new field-staggered 3G color filter pattern and a lenslet overlay, which doubles the sensitivity of the camera. The industrial-quality digital camera design offers improved image quality, reliability, and manufacturability, while meeting aggressive size, power, and cost constraints. The CFA processor digital VLSI chip includes color filter interpolation processing, an optical black clamp, defect correction, white balance, and gain control. The RGB postprocessor digital integrated circuit includes a color correction matrix, gamma correction, two-dimensional edge enhancement, and circuits to control the black balance, lens aperture, and focus.

“…With the trend towards integration of video into the digital domain, research groups are developing cameras which produce video in a digital format [9,10] that will come to replace television camera/capture board systems for live video applications. Similarly, with the trend towards distributed computing, video capture systems which connect directly to a network are becoming desirable.…”

This paper describes a stand-alone network-based video capture and processing peripheral (the Vidboard) for a distributed multimedia system centered around a gigabit-per-second Asynchronous Transfer Mode (ATM) network. The Vidboard captures video from an analog NTSC television source and transmits it to devices within the system. Devices control the Vidboard through a set of ATM protocols. Whereas capture boards typically generate video streams having fixed frame rate characteristics, the Vidboard is capable of decoupling video from the real-time constraints of the television world. This allows easier integration of video into the software environment of computer systems. The Vidboard is based on a front-end framememory processor architecture that is also capable of generating full-motion video streams having a range of presentation (picture size, color space) and network (traffic, pixel packing) characteristics. A series of experiments are presented in which video is transmitted to a workstation for display. Frame rate performance and a remote video source control model are described.
