Frame grabbers blaze
MaxRevolution family of pipeline image-processing frame grabbers for the PCI bus enables image acquisition from Camera Link-compatible digital linescan or area-scan cameras. Units can support up to eight camera taps, each running at up to 85 MHz, that can achieve a 680-Mpixel/s acquisition rate. Based on software-configurable and scaleable Xilinx Virtex II FPGA processing architecture, the frame grabbers can acquire, preprocess, and transfer images and results to host system memory via universal 64-bit, 66-MHz PCI bus interface at sustained rates of up to 360 Mpixels/s. On-board memory is expandable to 1 Gbyte using PC-2100 double-data-rate SDRAM. Units feature pixel gain and offset correction that compensate for gray-scale irregularities in both 1- and 2-D image sensors, on-board Run Length Encoding compression, multitap data reformatting on the fly, and connection to two Camera Link cameras for simultaneous acquisition, pipeline processing, and DMA transfer to host memory. Software support includes the company's Video Layered Library of C++ software-development tools. Datacube Inc., Danvers, MA 01923; (978) 777-4200.

Camera packs power
SI-3170 MegaCamera series of digital 1/2-in. CMOS cameras with C-mount provides 2048 X 1536-pixel resolution and runs at video rates of up to 30 frames/s at full resolution. Cameras use dual 12-bit digitizers to sample two output taps, each at 50 MHz, to achieve 100 Mpixels/s. Both the SI-3170M monochrome and the SI-3170RGB color cameras incorporate the Camera Link interface. Their CMOS sensor array contains 3.3-µm-square pixels that operate in full-frame or window mode. A reduced region of interest (windowing) provides readout rates in excess of 500 frames/s. The cameras are fully programmable via a serial port with flash memory for parameter storage and preset recall. Program-mable functions include sampling clock speed, region-of-interest window, and global gain. Silicon Imaging Inc., Troy, NY 12180; (518) 279-9098.
