High Dynamic Range Imaging
High dynamic range (HDR) images and video contain pixels, which can represent much greater range of colors and brightness levels than that offered by existing, standard dynamic range images. Such “better pixels” greatly improve the overall quality of visual content, making it appear much more realistic and appealing to the audience. HDR is one of the key technologies of the future imaging pipel...
متن کاملHigh Dynamic Range Panoramic Imaging
Most 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 elds of view have larger brightness ranges. We propose a simple modi cation to existing high resolution omnidirectional/panoramic cameras in which the process o...
متن کاملHigh Dynamic Range Imaging Technology
IN this lecture note, we describe high dynamic range (HDR) imaging systems; such systems are able to represent luminances of much larger brightness and, typically, also a larger range of colors than conventional standard dynamic range (SDR) imaging systems. The larger luminance range greatly improve the overall quality of visual content, making it appears much more realistic and appealing to ob...
متن کاملHigh Dynamic Range Astronomical Imaging
High dynamic range imaging methods that combine multiple exposures involve a number of processing details, such as frame alignment, motion artifact removal, and pixel data weighting. When applied to astronomical scenes, these steps require additional consideration. Specifically, motion blur artifacts must be corrected by techniques that are tolerant of saturated pixels, successive image frames ...
متن کاملMultispectral high dynamic range imaging
Capturing 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. The problem of the limited dynamic range of the camera has been addressed by high dynamic range imaging (HDRI): Several ...
