4-х канальный модуль полнокадрового видеозахвата miniPCI , -40~+85 ºC
Live Frame Capture up to 4 concurrent full size D1
PAL/NTSC/RS170 video inputs at Full Frame Rate.
The microGrabber is a 4-channel video capture and overlay controller on a single Type-III mini PCI card. The microGrabber provides a powerful and flexible solution for capturing up to four concurrent analog video inputs for local system display or software analysis and processing, ideal for compact embedded Situational Awareness systems.
The microGrabber allows each of the 4 video channels to be captured at full D1 size, all at full frame rate. The video can be scaled, cropped and positioned under software control. In addition to the video capture, the microGrabber also provides capture of up to 4 mono audio sources.
The captured video data can be streamed continuously to system memory or disk for either immediate local display or further processing. The capture engine of the microGrabber features hardware color space conversion to present the captured video data in the format best suited to the end application.
The microGrabber is support by a set of well -documented comprehensive SDKs that minimize development risk and shorten time-to-market. The SDKs are available on popular embedded operating systems such as Windows, Linux , and QNX.
