Abstract

HDR technology is the ability to display a wider range of light and dark colors on a screen. Both Valve and EA have produced videogames using HDR. The choice to implement HDR was made after many of the reference photographs, used to determine intended art style for the game, showed dramatic variations in the brightness of the lighting. In some ways, because it requires the use of fewer light sources, HDR cuts down on the amount of work lighters typically need to undertake. For example, using radiosity lighting from the sun causes light to bounce off surfaces around the game world. As such, lighters no longer have to place individual light sources in all parts of the world. It seems to be the bright, rather than the dark end of the scale, that is more important because often shows a greater level of detail in the game world.

... This is the essential difference between digital-domain TDI and charge-domain TDI. High Dynamic Range (HDR) technology [9][10][11] can effectively and clearly improve the brightness and color range of images. Compared with ordinary image processing methods, HDR technology can provide more dynamic performance and image details. ...

Due to the fact that traditional High Dynamic Range (HDR) imaging methods cannot be used for satellites, finding a way to generate HDR remot e sensing images from satellites has long been explored in the field of remote sensing imaging. In this paper, a systematic method of synthesizing HDR remote sensing images based on a new registration algorithm and virtual digital delay integration (TDI) technology is proposed. Firstly, a series of original images are generated by the fast continuous shooting method through push-broom spaceborne camera. Then, a new registration algorithm with high accuracy and high robustness is proposed in this paper is used for image registration. Finally, an HDR multi-frame image synthesis algorithm is used to generate high-quality and high signal-to-noise-ratio HDR images. This technology greatly improves the image information acquisition capabilities of digital TDI area scan cameras
