ACM SIGGRAPH 2004 Course Notes, 2004
Current display devices can display only a limited range of contrast and colors, which is one of the main reasons that most image acquisition, processing, and display techniques use no more than eight bits per color channel. This course outlines recent advances in high-dynamic-range imaging, from capture to display, that remove this restriction ...

2013 International Conference on Communication Systems and Network Technologies, 2013
While real scenes produce a wide range of brightness variations, current cameras use low dynamic range image detector that typically provide 256 levels of brightness data at each pixel. We propose methods to create High Dynamic Range images, the method to enhance the dynamic range of is based on capturing multiple exposure photographs of the scene ...

High-Dynamic-Range Image Reproduction Methods
IEEE Transactions on Instrumentation and Measurement, 2006The high dynamic range of illumination may cause serious distortions and problems in the viewing and further processing of digital images. Important information can be hidden in the highly or extremely lowly illuminated parts. This paper deals with the reproduction of such images and introduces two new tone reproduction preprocessing algorithms which ...

High Dynamic Range Display Adopting High Dynamic Range Imaging Technique
2006 IEEE LEOS Annual Meeting Conference Proceedings, 2006Technique of high dynamic range imaging (HDRI) was introduced into conventional high dynamic range display (HDRD). Sharpness of image was further enhanced by improving local contrast ratio in the HDRI-based high dynamic range display.

High dynamic range image hallucination
ACM SIGGRAPH 2007 sketches, 2007An apparatus and method provide for providing an output image from an input image. The input image may contain at least one portion that does not display certain desired information of the image, such as texture information. The desired information may be obtained from a second portion of the input image and applied to the at least one portion that ...

Super-high Dynamic Range Imaging
2014 22nd International Conference on Pattern Recognition, 2014We propose a novel high dynamic range (HDR) imaging algorithm for the scenes that contain an extremely wide range of scene radiance. In the HDR imaging, several images are taken under different exposures. Those images usually have displacement from one another due to camera and/or object motions. The challenge of the super HDR imaging is to align those

Multispectral high dynamic range imaging
SPIE Proceedings, 2008Capturing natural scenes with high dynamic range content using conventional RGB cameras generally results in saturated and underexposed and therefore compromising image areas. Furthermore the image lacks color accuracy due to a systematic color error of the RGB color filters.

Penrose high-dynamic-range imaging
Journal of Electronic Imaging, 2016High-dynamic-range (HDR) imaging is becoming increasingly popular and widespread. The most common multishot HDR approach, based on multiple low-dynamic-range images captured with different expo- sures, has difficulties in handling camera and object movements.

High dynamic range panoramic imaging
Proceedings Eighth IEEE International Conference on Computer Vision. ICCV 2001, 2002Most imaging sensors have a limited dynamic range and hence can satisfactorily respond to only a part of illumination levels present in a scene. This is particularly disadvantageous for omnidirectional and panoramic cameras since larger fields of view have larger brightness ranges.

Split Aperture Imaging for High Dynamic Range
International Journal of Computer Vision, 2002Most imaging sensors have limited dynamic range and hence are sensitive to only a part of the illumination range present in a natural scene. The dynamic range can be improved by acquiring multiple images of the same scene under different exposure settings and then combining them.
