With NI 1409 devices, you have the Image Acquisition with Calibration option to acquire in 8-bit or 10-bit mode at very high rates, such NI 1409 devices are gain calibrated and delivered with a as 60 frames/s with double-speed progressive scan cameras. calibration certiŢcate. Calibration ensures repeatable, consistent image acquisition for your machine vision and scientific Interchange Cameras with NI-IMAQ imaging applications. NI-IMAQ driver software for image acquisition can scale between many types of cameras and acquisition methods. With NI-IMAQ, Variable Scan and Nonstandard Video you can begin by using a low-cost RS-170 camera and image With NI 1409 devices, you can acquire images from nonstandard acquisition device and then upgrade to a faster, higher-resolution video, such as analog line-scan and variable-scan devices with camera and acquisition hardware with minimal software changes. pixel clocks that range from 2 to 40 MHz. The NI 1409 devices Because NI-IMAQ driver software uses one set of function work with double-speed (60 frames/s) progressive scan or calls for a wide variety of cameras, there is no need to rewrite noninterlaced monochrome cameras from vendors such as your software.

You can also map clock and horizontal and vertical synchronization signals. the lines to onboard status values (CSYNC, Acquisition in Progress, and Acquisition Complete). Image Acquisition Performance Gains with Partial Image Scanning Antichrominance and Lowpass Filter For improved throughput and processing bandwidth, the NI 1409 devices have an antichrominance Ţlter, which can remove acquisition and ROI control circuitry monitors the incoming video chrominance information from a color video signal. There are two signal and routes the active pixels to the FIFO. In addition to being software selectable antichrominance Ţlters – one for NTSC color able to digitize an entire frame, an NI 1409 can perform pixel and -coded signals (a 3.58 MHz notch Ţlter), and another for PAL color line scaling (decimation) and ROI acquisition. With pixel and line -coded signals (a 4.43 MHz notch Ţlter). Use the lowpass Ţlter at scaling, multiples (2,4,8) of pixels and/or lines can be transferred 9 MHz to remove unwanted noise. to the PCI bus. Using ROI acquisition, you select an area in the acquisition window that will be transferred to the PCI bus. 10-Bit A/D and Look-Up Table (LUT) An A/D converter performs the image digitization, the result of Hardware which passes to a 1,024 by 10 RAM LUT. You can conŢgure the PCI Interface LUT to implement simple imaging operations, such as gamma The PCI bus is the electrical interface for both NI PCI-1409 and manipulation, contrast enhancement, data inversion, or any NI PXI-1409. The PCI interface, implemented with the National nonlinear transfer function. Instruments MITE ASIC, can transfer data at a maximum sustained rate of 100 Mbytes/s in master mode to maximize the Programmable Gain and Offset use of the available bandwidth. The interface logic ensures that The NI 1409 has programmable gain and offset circuitry for the NI 1409 meets the loading, driving, and timing requirements optimizing the input signal range. of the PCI speciŢcation. VCR Circuitry Scatter-Gather DMA Controllers Because many commercial and home VCRs have noisy An NI 1409 has three independent onboard DMA controllers. The synchronization signals or no synchronization at all, VCRs are DMA controllers can transfer data between the Host memory and difŢcult to use with most image acquisition hardware. However, the onboard FIFO via the PCI bus. Each of these controllers with its built-in circuitry and logic for handling video signals from performs scatter-gather DMA, which means the DMA controller VCRs, the NI 1409 can acquire monochrome images from VCRs. can reconŢgure on the ţy, and thus perform continuous image transfers to either contiguous or fragmented buffers. Digital I/O The NI 1409 Series includes four general-purpose digital Onboard Memory input/output lines for general-purpose triggering and pulse An NI 1409 has 16 MB of onboard memory used to temporarily generation capabilities. In addition, each NI 1409 includes four store the image being transferred to the PCI bus. With 16 MB, digital output lines for lighting, shutter, camera control, and you can buffer large images during image acquisition. pulse generation. 592 National Instruments • Tel: (800) 433-3488 • Fax: (512) 683-9300 • info@ni.com • ni.com Vision 4-Channel Monochrome Image Acquisition 4-Channel Monochrome Image Acquisition Vision 591-593 4 Channel Mono 10/28/08 1:35 PM Page 593 4-Channel Monochrome Image Acquisition BNC Connector The BNC connector supplies an immediate connection to the Ordering Information VIDEO0 input of the NI 1409.
