Standards Development

Scope

This International Standard specifies a measurement procedure and its visualization for image flare at various angles of incidence for incoming light.

The methods of measurement are designed to enable the assessment of the performance of digital cameras by using image data outputted by the digital cameras. This standard does not specify the value for the allowable range for the image flare.

Purpose

In modern imaging technology “high dynamic range imaging” plays an important role not only in traditional photography but also in applications like automotive imaging and security cameras. For high dynamic range imaging image flare is often times the limiting factor. Measuring image flare as described in ISO 18844 has turned out to not be sufficient because often times flare is generated by a direct point light source that shines onto a camera. This light source can be within or outside of the field of view. A standardized measurement of this type of flare is essential to improve the image quality of cameras. This not only helps to produce better photographic images but also to avoid accidents in autonomous driving cars and the identification of scene objects in security cameras. For these reasons the standard should be developed as joint work with IEC/TC 79 and ISO/TC 22 administered by ISO/TC 42.
