BEAVERTON, ORE. Imagenation Corp. has introduced a digital frame grabber for the PCI bus that enables the use of digital cameras in vision systems.
Imagenation president George Fabel said the PXD1000 V2 works in high-resolution and high-speed machine-vision applications like semiconductor wafer inspection, medical imaging and high-speed industrial machine vision. It works with single-, dual- and four-channel digital area scan, line scan and time delay and integration (TDI) cameras.
Priced at $995, the frame grabber offers more memory and more flexibility in signal definition, Fabel said, with the ability to support both RS422 and RS644 input signals at up to 30 MHz and 40 MHz per channel, respectively. It is designed specifically for image-critical applications, he said, "where high data rates, advanced control options and high-resolution capture capabilities with superior dynamic range are essential. These include semiconductor wafer inspection, medical and scientific imaging, continuous web inspection, microscopy, high-speed industrial machine vision, motion analysis and object tracking and thermal imaging."
The frame grabber handles image sizes of up to 32k x 32k and features "excellent sustained 100-Mbyte/second PCI bus performance," Fabel said, "coupled with 4 Mbytes of on-board FIFO memory, which means no risk of losing important image data." It accepts data rates of up to 40 Mpixels/s per 8-bit channel and up to 160 Mpixels/s maximum with four-channel cameras.
The part comes equipped with camera configuration tools that let users create, modify and test configuration files, without having to know the frame grabber's internal architecture. A video window reacts to changes in real-time, to support interactive experimentation with a variety of camera parameters. It also comes with a camera configuration application for adding new cameras or reconfiguring existing ones. Preconfigured files for several operating modes of digital cameras are also provided.
The company's Web site offers additional downloadable software, including demo programs, sample code for instructions on grabbing and queuing frames, as well as controlling strobes and triggers, and a program for decoding an encoded filter-colored image into true RGB color, Fabel said. "This is invaluable in those applications where there is a need to discern more than one color at high resolutions in real-time, such as printing, food processing and pharmaceutical production," he said. The frame grabber is available now.
