1-101: Influence of ipRGCs on brightness perception

To prepare a technical report that summarizes the currently available information on brightness influenced by ipRGCs (intrinsically photosensitive retinal ganglion cells or melanopsin cells) which contain photopigment melanopsin. The report of the committee reviews the literature studies regarding the influence of melanopsin cells on brightness perception including brightness estimation models that take into account the influence of melanopsin cells on brightness perception used in these studies. These brightness estimation models are expected to improve the assessment of brightness perception influenced by melanopsin cells.
