Using data from a motion encoder, the frame grabber regulates the camera’s scanning rate. The camera’s acquisition line rate rises as the pieces move more quickly.
The camera’s acquisition line rate falls as the pieces move more slowly. The Grablink boards decode A/B signals from quadrature motion encoders to determine if a component is moving forward or backward.
It is an option to tell the Grablink to only pick up lines when the object is travelling forward or only when it is moving backward.
When a backward motion is detected, a feature called Backward Motion Cancellation halts the acquisition. When the motion is once more in a forward direction, the line acquisition immediately picks up right where it left off.
The camera may acquire lines at any programmable resolution, whether it is lower or higher than the resolution of the motion encoder, thanks to a rate converter.
Due to this, the application’s designer has a great deal of freedom and flexibility. The camera can acquire lines at a resolution that is less than the resolution of the motion encoder thanks to a rate divider. It divides the receiving encoder signal’s frequency by a programmable integer.
The Global Camera link frame grabber market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
An industrial PCI frame grabber called PC-CamLink makes use of the Camera Link interface for digital cameras.
To provide a high performance, reasonably priced interface to cameras meeting the Camera Link specification, PC-CamLink combines a half-slot PCI-bus frame grabber with Coreco Imaging’s high-speed image transfer architecture.
The PC-CamLink offers the user a customizable interface with support for clock rates up to 62.5 MHz for high speed, high resolution.
The PC-Camlink has a special feature called 16MB on-board memory that keeps the required high data transfer rates while lowering CPU usage and the chance of data loss.
As lines become available, PC-CamLink is capable of bus mastering image data directly to the host PC memory.
