Item HDR Photographic Pipeline for Camera Modules in Mobile Devices(The Eurographics Association, 2011) Mantiuk, R.; Cybularczyk, J.; Cichowicz, M.; Smyk, M.; Bazyluk, B.; A. Day and R. Mantiuk and E. Reinhard and R. ScopignoWe replace the standard image capture pipeline in mobile phones with an HDR acquisition pipeline based on the multi-exposure method. We report timings for basic HDR algorithms implemented in a smartphone with ARMv6 processor and discuss programming techniques that speed-up execution and reduce RAM memory usage. The results compare favourably to proprietary iPhone 4 HDR implementation and show that the HDR pipeline can be efficiently implemented on existing camera phones using high-level APIs and no dedicated hardware.
