| High Dynamic Range Imaging: Images and Sensors. |
|
In the past, technological development in the image sensor field primarily strove to increase resolution by adding pixels. The current generation of digital cameras already offer resolutions over 10 Megapixels. This allows details too small to be seen with the human eye to be im-aged, provided the optics are up to the task.
With regard to dynamic range, however, human sight is far superior to conventional image capturing devices. If a scene contains very bright and very dark areas, a camera will quickly reach its limits. While the eye can perceive all brightness levels, image sensors suffer from overexposure and therefore lose image data.
HDR (High Dynamic Range) technology, on the other hand, enables fine differences in bright-ness to be imaged even in very bright scenes, similar to the human eye. This white paper ex-plains the background behind HDR technology and the method of functioning of HDR image sensors. Finally, potential uses and limits of the new technology will be identified |
| USB 3.0 – Background Factors, New Features, and Applicability as a Camera Interface |
|
In November 2008, the specification for “SuperSpeed USB” was presented and marked an improved and, above all, considerably faster version of the popular interface.
New features on the protocol level as well as on the hardware side promise to eliminate some of the limitations imposed by version 2.0.
This article presents the main characteristics of USB 3.0 as well as its benefits when used as a camera interface for image processing. |
