Third time is a charm - MATRIX VISION's PCI Express frame grabbers
Starting to sell the mvDELTAe, MATRIX VISION now offers three PCI Express frame grabbers for different application areas.
The image processing board represents an cost-effective first step into almost all image digitization applications, e.g. in quality assurance, surveillance systems, microscopy and medical engineering. Images are digitized in high quality with the full PAL resolution of 768 x 576 pixels. For this purpose, board provides four software-switchable video inputs (with up to 50 frames per second) for composite video signals whereas one input can be operated optionally as a Y/C input. Image parameters such as contrast, brightness and colour saturation can be set digitally. Digitized images can be scaled horizontally and vertically pixel by pixel using an interpolating scaler. The mvSIGMA-SQe is mainly aimed at the surveillance market. The board offers 16 CVBS/gray or four Y/C video inputs, whereof four video channels can be acquired independently and simultaneously. The frame grabbers reach a frame rate up to 200 frames per second (color format: YUV 4:2:2), i.e. per channel up to 50 frames per second. Beside progressive scan, also interlaced scan as well as the common video enconding format CIF (352 x 288 pixels) are supported. Asynchronized and synchronized cameras can be used with the frame grabber. Using several cameras the switching time of synchronized cameras amount to 0 msec (asynchronized cameras: 0 up to 40 msec). On the high end of the performance spectrum, primarily for image acquisition and image processing applications in the fields of science and industry, increasingly grabbers with a CameraLink interface have gotten in place. For this performance spectrum MATRIX VISION offers the mvHYPERION-CLe. The board features beside two data channels also interfaces to control trigger and flash of two cameras independently. Furthermore the mvHYPERION-CLe has a local DDR-RAM memory with 64 MB, so that no data loss appears during high system load.
It does not matter how different the application areas are, all three frame grabbers have the same advantage: each component connected to the PCI Express bus has the full PCIe data transfer bandwidth of 250 Mbytes/s (single lane) exclusively. Thus several frame grabbers can be used in the same system without essential opposite inteferences.
Another plus is the image processing library mvIMPACT. All three frame grabbers include the base module of the library as well as the drivers for Windows and Linux in the scope of supply.
