Additional Machine Vision Standards


CoaXPress The CoaXPress digital interface was developed for high speed image data transmission and intended mainly for machine vision applications. The interface is also suitable for other imaging applications and for high speed data transmission in other fields. CoaXPress uses 75 Ω coaxial cable as a physical medium.

CoaXPress is hosted by the Japan Industrial Imaging Association (JIIA). The JIIA CoaXPress Technical Committee is responsible for the preparation and maintenance of the standard. Contributions are also made by the CoaXPress Consortium and the CoaXPress Liaison Group, which is for members of the AIA and EMVA. For more information, please visit

EMVA 1288

1288 defines a unified method to measure, compute and present specification parameters for cameras and image sensors used for machine vision applications. Application of this standard will benefit users of vision components by avoiding misunderstanding and reducing pre- and post-support cycles. 

The standard is elaborated by a consortium of the industry leading sensor and camera manufacturers, distributers and component customers and is hosted by the European Machine Vision Association (EMVA). For more information please visit


The goal of GenICamTM is to provide a generic programming interface for all kinds of cameras. No matter what interface technology (GigE Vision, Camera Link, 1394 DCAM, USB, etc.) they are using or what features they are implementing, the application programming interface (API) should be always the same.
The GenICam standard consists of multiple modules according to the main tasks to be solved: 

  • GenApi: configuring the camera
  • Standard Feature Naming Convention (SFNC): recommended names and types for common features
  • GenTL: transport layer interface, grabbing images

The GenICam standard group is hosted by the European Machine Vision Association (EMVA). For more information please visit

Lens Mount Standards by JIIA

Lens Mounts for Machine Vision Cameras – NF Mount Standard and Operational Regulations
This standard specifies the fixing screws and flange focal distance of NF mount machine vision cameras.

Lens Mounts for Machine Vision Cameras – Lens Mount Sizes
This standard provides the lens mount sizes matched to image sizes for industrial cameras.

Lens Mounts for Machine Vision Cameras – Classification of Images Sizes
This standard provides the classification of image size of lens mounts industrial cameras.

The standards are hosted by the Japan Industrial Imaging Association (JIIA). Visit for more information.

Pixel Format Naming Convention v1.1 (PFNC v1.1)

The Pixel Format Naming Convention (PFNC) version 1.0 was created in November 2011 by the GigE Vision technical committee to generalize the definition and layout of various pixel formats so they can be reused by the various machine vision standards. Version 1.0 introduces an appendix to list the recommended pixel format ID to be used as a unique identifier for a given pixel format. These IDs are available as 32-bit and 16-bit values. This enables the different camera interface standards to share the same values, hence simplifying software development. GigE Vision 2.0, USB3 Vision 1.0 and CoaXPress 1.0 are all supported by this new appendix. Additionally, PFNC v1.1 adds some new pixel formats to support the USB3 Vision 1.0 specification.
