{HiDyn} Deliverable D3 - Report on the relevance of existing quality indices and the need for new ones, specific to HDR imaging luminance measurement systems, for glare and obtrusive light assessment

In this report the relevance of the of existing quality indices described in CIE 244:2021 to calculate glare metrics is evaluated.Some of the indices are almost not relevant for the glare metrics as metrics apply typically a logarithmic function on the luminance. However, indices related to the linearity, shutter and aperture repeatability, light modulation, size of source and smear have a high impact on the glare metrics, and such influences should be minimized during the acquisition of the HDR images. This report evaluates the relevance of existing quality indices described in CIE 244:2021 to calculate glare metrics. The evaluation is based on the experience of the participants of the HiDyn project and the measurements conducted in the framework of the project. The project team also suggests an additional, new quality index.
