I-Color Frame Grabber
Not your average color frame grabber. Unlike other color video frame grabbers, I-Color by Foresight Imaging is not based upon "reference designs" from the decoder chip manufacturers. Instead, I-Color is a member of the high accuracy, high performance I-Series of frame grabbers and video streamers. I-Color is based upon the I-Series architecture, guaranteeing the same high speed PCI bus transfers and video streaming as well as the superior image accuracy that Foresight Imaging has built its reputation upon to service demanding applications in medical imaging, scientific imaging, and machine vision.
I-Color delivers the diagnostic-quality and inspection-quality images that demanding customers in medical imaging and metrology applications require. Low pixel jitter of ±2.0 ns, superior analog design, and a 47 dB S/N ratio provide the accuracy and precision needed in high performance applications. Color video digitization is performed at either 16 or 24 bits, while monochrome acquisitions are 8 bits. Color formats include YUV 4:2:2 and RGB 8:8:8.
As a member of the I-Series of frame grabbers and video streamers, I-Color has the identical high-speed PCI bus mastering, scatter-gather technology, and double buffering. This leading technology delivers over 120 MB/second sustained transfers to system memory. Such high performance requires minimal CPU intervention so that it is free to work on other tasks or process the incoming data immediately. Consecutive video images are transferred in real-time to system memory enabling real-time video streaming applications, such as cine loop cardiology, to utilize the power of the I-Series. Real-time streaming to disk is also supported with appropriate high performance disk drives. Real-time display is simultaneously enabled with any one of two methods: 1) Real-time transfer of image data directly to display card memory over the PCI bus, or 2) Real-time transfer using the VIP/VMI over-the-top bus to industry-standard display cards.
I-Color supports up to four standard video inputs from a variety of cameras and medical input devices. The four inputs can be mixed between the following video input formats: composite color, S-Video, monochrome, NTSC, PAL, RS-170, and CCIR. For fine-tuning of the video signal, 8 bit brightness, contrast, hue, and saturation controls are available. Scaling and windowing of the video input are provided.
In addition to its leading performance and accuracy, I-Color provides the controls necessary for many imaging applications: a dedicated external trigger and camera power at +12 V DC.
I-Color is supported by the IDEA (Imaging Development Environment for Applications) software development kit. By using IDEA, developers have the confidence of knowing that they can write their applications once and have support built-in for the entire I-Series (both current and future) and AccuStream product families. Eliminated forever is the need to re-write software every time a new frame grabber related requirement arises or a new board is introduced. The software compatibility built into the architecture of IDEA allows the simple movement to other products in the I-Series or AccuStream family. With IDEA, ActiveX controls are provided to facilitate easy development with Visual Basic, Visual C++, and Delphi. Extensive example programs (with source code) are provided with I-Color. Functions of the example programs include triggered acquisition, video streaming to AVI files, integration with Pegasus Imaging compression software for streaming, and overlays. For users with higher level application requirements, drivers are available for Common Vision Blox, Image-Pro Plus, Optimas, and TWAIN.
