eGrabber Memento

In high-end inspection machines using vision, the frame grabber is responsible for acquiring images in synchronization with numerous external devices such as motion or lighting controllers, not to mention the camera itself.
Debugging these systems often requires complex equipment, for example, oscilloscopes and logic analyzer, which are used along with software profilers. The problem is even more acute with the latest cameras available, which allow for very fast frame rates exceeding several hundred, even thousand frames per second.
Memento has been designed to simplify that process. During the operation, Memento records a very detailed log of events related to the camera, the frame grabber and its driver, as well as the host application.

Memento provides a logic analyzer tool, called Memento Analyzer, that receives detailed, sequenced and timing information to help measure latencies and detect defects during acquisition.
The Memento Analyzer displays system events (trigger, strobe, DMA, …) on a timeline.
It analyzes how buffer queues are used and how acquired images are delivered to the application. It also displays detailed information about incoming protocol data (CoaXPress, …).

eGrabber

• Extended support for GPU Direct DMA with DMA-BUF memory type

This release of eGrabber adds the support for GPU Direct DMA using DMA-BUF descriptors.
DMA‑BUF is the standard Linux mechanism for safe, efficient, zero‑copy sharing of memory buffers across drivers and processes, widely used in graphics and multimedia stacks.
Note: The DMA-BUF memory type is only supported on Linux.

• New built-in script to save/restore the GenApi configuration

The built-in script egrabber://create-restore-script.js captures the current values of the grabber features and creates a script to restore the configuration. The new script is directly available in eGrabber Studio (from the Script pane or from the Terminal)

Frame Grabbers

• Extended support for Horizontal Image Flipping

This release of eGrabber adds the support for Horizontal Image Flipping to the “2-camera, line-scan” firmware variant of PC1633 Coaxlink Quad G3 and PC1633-LH Coaxlink Quad G3 LH frame grabbers.
The horizontal image flipping function, also known as horizontal mirroring, is a process in which an image is flipped along its vertical axis. This means that the left side of the image becomes the right side and vice versa.

Memento

• New option “Reset columns to default settings”

This release of Memento includes this new menu entry to reset the memento viewer columns to their default settings (widths, font size and visibility).

• Improved performance of Memento GUI

Improved the reactivity of the viewer when the count of selected rows is high.
