JAI, a manufacturer of industrial-grade cameras, has begun shipping the latest cameras in its 3-CCD color camera series, the AT-140GE and the AT-200GE, the company says in a written statement.
The AT-140GE and the AT-200GE feature the same 1.4-megapixel and 2-megapixel resolution as previous JAI -CCD color camera, and are equipped with GigE Vision serial interfaces able to operate via standard Ethernet cabling and network hardware, says JAI, which is a multi-national corporation with facilities in San Jose, Calif.
In addition, while the AT-140GE features three 1/2-inch progressive scan CCDs (Sony ICX267AL), each with a resolution of 1392 x 1040 pixels and an individual pixel size of 4.65 by 4.65 microns.
The AT-200GE uses three 1/1.8-inch progressive scan CCDs (Sony ICX274AL) to provide a resolution of 1628 x 1236 pixels with an individual pixel size of 4.4 microns square.
The CCDs are affixed to a prism block that splits the incoming light into red, green, and blue color channels. JAI's patented alignment process ensures the three sensors are aligned to within 1/4-pixel accuracy, providing pixel-precise color values suitable for machine vision analysis, gauging, and processing. This is in contrast to 3CCD cameras that utilize “pixel offset” methods to increase perceived on-screen resolution, while sacrificing the precision of the digital output.
With their 3-CCD technology, the cameras are particularly suitable for print inspection, paint matching, medical diagnostics, or other applications where extremely accurate color values are required, JAI says. A sophisticated linear color matrix circuit enables precise color matching between camera data and calibrated printers, monitors, and other devices. Users can manually tune the RGB channels, or can choose from preset sRGB or Adobe RGB industry standard color space settings developed by HP, Microsoft, and Adobe.
