The National Instruments 778838-01, known as the PCI-1405 Image Acquisition Board, is a versatile solution designed for high-performance image acquisition from a variety of analog cameras, accommodating both monochrome and color images. This board features real-time image capture capabilities, allowing users to store images in 16 MB of onboard high-speed SDRAM or transfer them directly to the system's memory. Supporting industry-standard NTSC and PAL video formats, the PCI-1405 includes an integrated video decoder that converts incoming video signals into RGB data, enabling precise user adjustments for input range, brightness, contrast, saturation, and frequency range. The module's advanced circuitry facilitates video acquisition from VCRs, making it ideal for diverse applications. With three independent DMA controllers, the PCI-1405 efficiently manages data transfers between the SDRAM and PCI bus, achieving a maximum data transfer rate of 132 MB/s in bus master mode. The PCI interface utilizes the PCI MITE custom ASIC, which supports 8-, 16-, and 32-bit memory read and write cycles. To streamline integration, the device is bundled with the NI Vision Acquisition Software, including the NI-IMAQ driver, which provides a comprehensive suite of functions for video configuration, acquisition modes, trigger control, memory buffer allocation, and device setup. Users can initiate image acquisition through various methods such as software control, trigger signal responsiveness, or frame/field selection, thus allowing control over the acquisition window and selectable regions of interest within the image frame.
