HDR video acquisition and processing are quite challenging tasks from the point of both computational complexity and algorithm design. In this paper, we present a real-time HDR processing system evaluated on a custom hardware camera platform. We exploited well known state of the art algorithms for HDR acquisition from sequence of multiexposure frames and real-time tone-mapping. We also present modifications of the algorithms enabling efficient implementation on FPGA platform and real-time performance. The main focus of the paper is on acceleration of Durand local tone-mapping operator involving real-time bilateral filter. The proposed solution is compared to existing research results in terms of speed, resource consumptions, and numerical accuracy.
