—This paper describes the HDR-ARtiSt hardware platform, a FPGA-based architecture that can produce a real-time high dynamic range video from successive image acquisition. The hardware platform is built around a standard low dynamic range (LDR) CMOS sensor and a Virtex 5 FPGA board. The CMOS sensor is a EV76C560 provided by e2v. This 1.3 Megapixel device(More)
—Many camera sensors suffer from limited dynamic range. The result is that there is a lack of clear details in displayed images and videos. This paper describes our approach to generate high dynamic range (HDR) from an image sequence while modifying exposure times for each new frame. For this purpose, we propose an FPGA-based architecture that can produce a(More)
This paper describes a complete FPGA-based smart camera architecture named HDR-ARtiSt (High Dynamic Range Adaptive Real-time Smart camera) which produces a real-time high dynamic range (HDR) live video stream from multiple captures. A specific memory management unit has been defined to adjust the number of acquisitions to improve HDR quality. This smart(More)
Recommended by Dragomir Milojevic A high-speed analog VLSI image acquisition and low-level image processing system are presented. The architecture of the chip is based on a dynamically reconfigurable SIMD processor array. The chip features a massively parallel architecture enabling the computation of programmable mask-based image processing in each pixel.(More)
Temporal exposure bracketing is a simple and low cost technique to generate a high dynamic range (HDR) images. This technique is widely used to recover the whole dynamic range of a scene by selecting the adequate number of low dynamic range (LDR) images to be fused. Temporal exposure bracketing technique is introduced to be used for static scenes and it(More)
—A camera is able to capture only a part of a high dynamic range scene information. The same scene can be fully perceived by the human visual system. This is true especially for real scenes where the difference in light intensity between the dark areas and bright areas is high. The imaging technique which can overcome this problem is called HDR (High(More)
