You may know the trouble of comparing different cameras to objectively find out what model is best for your application. Unfortunately, data sheets are often incomparable, and important information is often missing, so that the user is forced to go through the trouble and cost of investigating each camera in its details. The European Machine Vision Association (EMVA) has realized this lack of data conformity. The EMVA has created an industry standard, i.e., EMVA 1288, which gives users objective transparency by providing exact and reliable measurement methods as well as uniform guidelines for presentation of data. This greatly simplifies the comparison of cameras and image sensors.
The EMVA standard is developed by a working group of leading manufacturers of cameras and image sensors, distributors and scientific institutions. The first version of the EMVA 1288 standard was published in August 2005. The latest version can be downloaded free of charge from www.emva.org.
Today, the EMVA standard is used around the globe, providing an objective basis for specification of cameras and image acquisition sensors. This has helped making EMVA 1288 the basis for an objective characterization of cameras and sensors. The standard strictly characterizes the devices according to physical parameters. It focuses on the camera without a lens and introduces objective criteria for rating sensitivity, noise, spectral sensitivity, dark current, homogeneity and defective pixels.
