GenICam (Generic Interface for Cameras) represents a significant standard in the machine vision industry. It provides a universal programming interface that allows cameras from different manufacturers to be controlled consistently, regardless of their underlying technology (CoaXPress, GigE Vision, Camera Link, USB3 Vision, etc.) [Source: EMVA].

At its core, GenICam acts as a common API for application software to interact with cameras in a standardized way. This is similar to how Photoshop can handle images from any scanner without regard to the brand or connection method.

Key Functions Supported by GenICam

According to the GenICam standard, it supports five fundamental functions:

  1. Camera Configuration: This function allows users to adjust various camera parameters such as frame size, acquisition speed, pixel format, gain, and image offset.
  2. Image Grabbing: It enables seamless communication between the camera and user software by establishing access channels for receiving images.
  3. Graphical User Interface (GUI): Users can interact with cameras through a standardized GUI interface, simplifying control regardless of hardware specifics.
  4. Transmission of Extra Data: Cameras can send additional data alongside image information, such as histograms, timestamps, or areas of interest in the frame.
  5. Event Delivery: This function allows cameras to communicate events via an event channel, enabling real-time notifications without polling.

The Evolution and Importance of GenICam

Compared to traditional machine vision interface standards like Camera Link, which heavily relied on frame grabbers, GenICam offers a more abstract approach. While early systems depended on proprietary hardware, modern standards such as GigE Vision and USB3 Vision allow direct computer integration. This shift has increased the importance of GenICam for simplifying interoperability across diverse camera technologies, including CoaXPress—which still requires frame grabbers in some cases.

With CoaXPress cameras, GenICam enables a standardized programming interface that allows users to connect directly with any compatible camera and software layer without worrying about brand or implementation details. For instance, developers can use tools like HALCON from MVTec for machine vision tasks such as measurement, identification, or 3D vision.

The goal of GenICam is to provide a plug-and-play experience where users can easily switch between different cameras or suppliers while focusing on their application logic rather than hardware specifics. This approach streamlines development processes and encourages innovation within the machine vision market.

Addressing Concerns About Standardization

One common concern with standards like GenICam is that they might homogenize cameras, potentially reducing competitive differentiation. However, far from limiting uniqueness, these interfaces ensure that special features can be implemented without complicating user experience or application code. This balance allows manufacturers to innovate while maintaining broad compatibility and ease of use.
