High dynamic range imaging with PERIODIC
Proceedings of the 46th Annual Southeast Regional Conference on XX, 2008This paper presents an approach for improving the effective dynamic range of a novel array imaging systems by using multiple images of the same scene taken with different exposure times and gain values. In this approach, multiple images are fused into a single high dynamic range radiance map whose intensities are proportional to the true radiance ...

High dynamic range ultrasound imaging
International Journal of Computer Assisted Radiology and Surgery, 2018High dynamic range (HDR) imaging is a popular computational photography technique that has found its way into every modern smartphone and camera. In HDR imaging, images acquired at different exposures are combined to increase the luminance range of the final image, thereby extending the limited dynamic range of the camera.

High-dynamic-range video solution
ACM SIGGRAPH ASIA 2009 Art Gallery & Emerging Technologies: Adaptation, 2009The natural world presents our visual system with a wide, ever-changing range of colors and intensities. Existing video cameras are only capable of capturing a limited part of this wide range with sufficient resolution. High-dynamic-range (HDR) images can represent most of the real world's luminances, but until now capturing HDR images with a linear ...

Approaches to high dynamic range video
2016 Digital Media Industry & Academic Forum (DMIAF), 2016The television industry is excited about high dynamic range (HDR) video and its potential for dramatic improvements in picture quality. Together with wide colour gamut, brighter displays and ultra-high definition resolution, HDR represents a fundamental change in television which is, arguably, the biggest change since the development of colour ...

Noise in high dynamic range imaging
2008 15th IEEE International Conference on Image Processing, 2008High dynamic range (HDR) imaging is more and more widely used to increase the limited dynamic range of digital cameras and, in turn, to cover the dynamic range of the acquired scene. This image acquisition process can be subdivided into two steps. The first step is the measurement or estimation of the mostly non-linear camera transfer function (CTF ...

High dynamic range intelligent effects
2014 International Conference on Machine Learning and Cybernetics, 2014Recently, many mobile electronic devices, such as mobile phones and digital cameras, are equipped with a new function: High dynamic range (HDR), which can take better quality of photos, and create better selling record also. Actually, HDR effects deliver a mixture range of images of the same picture into a new photo. This new technique offers all kinds

Streamed high dynamic range imaging
2012 International Conference on Field-Programmable Technology, 2012The problem of mapping from a high dynamic range image, or a series of images spanning a wide dynamic range, to a standard 8-bit image is considered. Several techniques for dynamic range compression are reviewed. FPGA implementations are developed and demonstrated, with a focus on directly processing the video stream from the camera.
