A digital frame grabber is a piece of technology that “grabs” individual digital still frames from a digital video stream or an analogue video feed.
It is typically used as a part of a computer vision system, where video frames are digitally collected and then displayed, stored, communicated, or combined analysis.
Frame grabber expansion cards were traditionally the most common method of connecting cameras to PCs.
Since then, further interface techniques have developed, with frame grabbers (and occasionally cameras with built-in frame grabbers) connecting to computers via interfaces like USB, Ethernet, and IEEE 1394. (“FireWire”).
While many modern frame grabbers can save multiple digital video frames, early frame grabbers often only had enough memory to store one.
Modern frame grabbers frequently have capabilities beyond just recording a single visual feed. For instance, some systems supply and simultaneously capture frames from numerous video inputs, while others capture audio in addition to video.
Deinterlacing, text or graphic overlays, image transformations (including scaling, rotation, and mirroring), and conversion to JPEG or other compressed image formats are among the additional procedures that may be carried out.
Some frame grabbers can capture images at high frame rates, high resolutions, or both to meet the technological requirements of applications including radar acquisition, manufacturing, and remote guidance.
The Global digital frame grabber market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
A ruggedized 6U board designed for the CompactPCI bus and for usage in industrial settings, the PHX-D48CL-CPCI64-6U from Active Silicon Ltd.
has improved its range of Phoenix Camera Link digital frame grabbers. It can capture up to 533 MB/s and supports the 64-bit, 66-MHz interface.
It can receive input from one medium camera, one or two base cameras, and two asynchronous base cameras when using the two-camera input approach.
Line and pixel interleaved multitap and multichannel formats are also supported. TTL, LVDS, and opto-isolated input/output are onboard features.
Functionality for Bayer image decoding, sequence capture, and storage is included in the software developer’s kit. Every significant operating system is supported.
