A Real-Time FPGA-Based Architecture for a Reinhard-like Tone Mapping Operator

Abstract

This paper presents a field-programmable gate array-based hardware architecture for a Reinhard-like tone mapping operator. Modifications to the original Reinhard operator were done to ensure that the operator is amenable to implementation in hardware. The architecture is described in VHDL and has been synthesized using Altera Quartus tools. It achieves an operating frequency consistent with a video rate of 60 frames per second for a frame of 1024×768 pixels. The quality of the implementation is measured using peak signal-tonoise ratios on testbench images.
