Abstract: Based on the discussing of the fundamental concept and acquisition technology of High Dynamic Range Image (HDRI), several encoding technical methods and approaches of HDRI are analyzed and studied, and characteristics and applications are explored respectively. Meantime, tone mapping technology of HDRI is also discussed, and the calculation of background intensity is studied. Finally, the application fields of HDRI are prospected and forecasted.
