High Dynamic Range Images Using Exposure Metering
ثبت نشده
چکیده
The dynamic range is a ratio between the maximum and minimum physical measures. Its definition depends on what the dynamic range refers to. For a scene, dynamic range is the ratio between the brightest and darkest parts of the scene. For a camera, dynamic range is the ratio of saturation to noise. More specifically, ratio of the intensity that just saturates the camera to the intensity that just lifts the camera response one standard deviation above camera noise. For a display, dynamic range is the ratio between the maximum and minimum intensities emitted from the screen.

Metering for Exposure Stacks
When creating a High-Dynamic-Range (HDR) image from a sequence of differently exposed Low-Dynamic-Range (LDR) images, the set of LDR images is usually generated by sampling the space of exposure times with a geometric progression and without explicitly accounting for the distribution of irradiance values of the scene. We argue that this choice can produce sub-optimal results both in terms of th...
متن کاملMotion Aware Exposure Bracketing for HDR Video
Mobile phones and tablets are rapidly gaining significance as omnipresent image and video capture devices. In this context we present an algorithm that allows such devices to capture high dynamic range (HDR) video. The design of the algorithm was informed by a perceptual study that assesses the relative importance of motion and dynamic range. We found that ghosting artefacts are more visually d...

u t w c M a r m b s r s e v e m bstract. To acquire a high dynamic range (HDR) image of a cene, several low dynamic range (LDR) images acquired from a igital camera with different exposure times are generally fused into ne HDR image to cover the entire dynamic range of the scene. owever, when capturing a scene, the scene dynamic range (SDR) s unknown. Consequently, the exposure times for the LD...
متن کاملVisualizing High Dynamic Range Images in a Web Browser
We present a technique for embedding high dynamic range (HDR) images with interactive exposure control in a web browser. Multiple exposures are encoded as a combination of several basis images, which are stacked together and displayed with different opacity values. The combination of such basis images yields the resulting exposure image. An intuitive interface based on JavaScript callback funct...
متن کاملExposure Fusion: iOS App
In this paper, I present the Exposure Fusion app to capture high dynamic range images. The app provides functionalities to capture images with various exposure settings (exposure bracketing) and fuse the images into a high dynamic range (HDR) image. The app is developed in Swift and is compatible with iOS devices. The Exposure Fusion app implements the Exposure Fusion algorithm developed by Tom...
