AccuStream 50a, 75a & 205a Frame Grabber & Video Streamer
The AccuStream Series of frame grabbers and video streamers is the most advanced, most versatile series of products from Foresight Imaging. The AccuStream 50a, 75a, & 205a provide all-in-one video input functionality: high resolution RGB, YPbPr, monochrome, S-video, and composite color video inputs all in one half-size PCI board. Input pixel rates are up to 170 MHz (50 MHz for the AccuStream 50a, 75 MHz for the AccuStream 75a) and 2048 x 2048 pixels, providing acquisition from virtually any analog video source. The AccuStream Series also provides extreme performance delivering sustained transfers to system memory of 250 MB/second using its 64 bit, 66 MHz PCI bus design. For example, the AccuStream 205a can stream to memory 1280 x 1024 x 60 Hz video without dropping any frames. In addition to 64 bit, 66 MHz PCI, the AccuStream Series is compatible with 32 bit PCI and PCI-X slots.
The AccuStream Series continues in the Foresight Imaging tradition of delivering extreme accuracy and image quality for demanding customers with high resolution and precision applications. Extremely low pixel jitter of ±0.5 ns, superior analog design, and a 47 dB signal-to-noise ratio provide the accuracy and image fidelity required of high performance applications. Color video digitization is performed at 8 bits each of R, G, and B (24 bits per pixel) or 24 bit Video YPbPr. Monochrome acquisitions are at 8 bits per pixel. Pixel formats include RGB 24, RGB 32, RGB 5:5:5, RGB 8, YCbCr 4:2:2, YCbCr 4:4:4, and 8 bit monochrome.
The AccuStream Series achieves its extreme 250 MB/second sustained performance via its 64 bit, 66 MHz PCI bus mastering design, scatter-gather technology, and double buffering. This high performance requires minimal CPU intervention so that the processor is free to work on other tasks or process the data immediately. Real-time display is simultaneously enabled by real-time transfer of image data directly to display card memory over the bus. AccuStream also features independent, dual video data paths, allowing for the simultaneous DirectDraw display of YCbCr 4:2:2 color video and the transfer of full 24 bit RGB video data for processing.
The AccuStream 205a acquires images and video streams from both non-standard and standard video inputs up to 170 MHz RGB, YPbPr, monochrome, S-video, and composite color (50 MHz for the AccuStream 50a, 75 MHz for the AccuStream 75a). With this range of video formats and high frequency acquisition, the AccuStream Series can be used in virtually any application requiring analog video input. Input resolution is up to 4 megapixels total area. For fine-tuning of the video signal, gain, black level, white balance, and phase controls are provided. Separate H and V sync are supported. An external trigger is available.
The AccuStream Series is supported by Auto-SYNC™, Foresight Imaging's flagship automatic configuration software. Auto-SYNC ensures quick and simple installation and image capture by automatically configuring AccuStream to the incoming standard or non-standard video signal. Auto-SYNC automatically analyzes the incoming video signal and builds a configuration file. Use the configuration file as created or utilize the Auto-SYNC Wizard for simple, step-by-step video adjustments. AccuStream is supported, developers have the by the IDEA (Imaging Development Environment for Applications) software development kit. By using IDEA™ confidence of knowing that they can write their applications once and have support built-in for the entire AccuStream Series. A Video for Windows driver and a TWAIN driver are included to further simplify development and use of AccuStream. With IDEA, ActiveX controls are provided to facilitate easy development with Visual Basic and Visual C++. Extensive example programs (with source code) are provided with IDEA. Functions of the example programs include triggered acquisition, video streaming to AVI files, integration with Pegasus Imaging compression for streaming, overlays, and much more. Auto-SYNC, IDEA, example programs, and drivers are provided free of charge with each AccuStream.
