Major benefits using a frame grabber help to achieve the optimum results for a vision system to take advantage from maximum speed and throughput. The frame grabber can transmit a general signal “image ready” to the Signal Processing System (SPS) or other connected devices to leverage this type of automation when used for example, as an output manager. They allow for many different acquisition processes and to manage the deceleration of image processing in the background of application processes. The frame grabber accepts fast trigger sources and/or encoder inputs to seamlessly synchronize with the movement of objects in the image captures. They are also able to do all image processing and any additional manipulation of the image data onboard. Frame grabbers completely handle all tasks required to move this data to and from the memory, freeing the CPU to do other tasks. The Direct Memory Access (DMA) controller in the frame grabber avoids overloading the CPU with image transfer operations by moving the image data to the PC’s RAM memory directly or vice versa.

It manages the image data load from the camera to the memory of the PC by utilizing the capabilities of the PCI bus. Essentially, the frame grabber enables the high-speed image acquisition of high resolution images with special synchronization features in real-time. It is important to know the functionality and purpose of a frame grabber to better understand if this device is right for a specific imaging system and application.

Using frame grabbers in industrial environments brings specific benefits for high-speed applications in terms of speed, data security and synchronized processing for multiple cameras. The current implementation of high bandwidth interfaces like 10GigE, direct camera to PC connections and embedded systems prompts many users of imaging applications to inquire both about optimally connecting their cameras in the best possible configuration. Increasing sensor resolutions and framerates help reaching the goal, but bring bandwidth to their limits and offer new transfer questions. Reaching maximum throughput is one of the crucial criteria in industrial and factory automation.
