Analysis and compensation of rolling shutter effect.

AbstractDue to the sequential-readout structure of comple-mentary metal-oxide semiconductor image sensor array, eachscanline of the acquired image is exposed at a different time,resulting in the so-called electronic rolling shutter that inducesgeometric image distortion when the object or the video cameramoves during image capture. In this paper, we propose an imageprocessing technique using a planar motion model to addressthe problem. Unlike previous methods that involve complex 3-Dfeature correspondences, a simple approach to the analysis ofinter- and intraframe distortions is presented. The high-resolutionvelocity estimates used for restoring the image are obtained byglobal motion estimation, Bzier curve fitting, and local motionestimation without resort to correspondence identification. Exper-imental results demonstrate the effectiveness of the algorithm. T HE DEMAND for image sensors is growing rapidly dueto the increasing popularity of digital video cameras insurveillance, personal communications, consumer electronics,etc.

We demonstrate an approach that allows taking videos at very high frame-rates of over , frames per second by exploiting the fast sampling rate of the standard rolling-shutter readout mechanism, common to most conventional sensors, and a compressive-sampling acquisition scheme. Our approach is directly applied to a conventional imaging system by the simple addition of a diffuser to the pupil plane that randomly encodes the entire field-of-view to each camera row, while maintaining diffraction-limited resolution.

Analysis and Compensation of Rolling Shutter Effect Abstract: Due to the sequential-readout structure of complementary metal-oxide semiconductor image sensor array, each scanline of the acquired image is exposed at a different time, resulting in the so-called electronic rolling shutter that induces geometric image distortion when the object or the video camera moves during image capture.

Rolling shutter is a method of image capture in which a still picture in a still camera or each frame of a video in a video camera is captured not by taking a snapshot of the entire scene at a single instant in time but rather by scanning across the scene rapidly, either vertically or horizontally. In other words, not all parts of the image of the scene are recorded at exactly the same instant. Though, during playback, the entire image of the scene is displayed at once, as if it represents a single instant in time. This produces predictable distortions of fast-moving objects or rapid flashes of light. This is in contrast with " global shutter " in which the entire frame is captured at the same instant.

Analysis and Compensation of Rolling Shutter Effect

This paper proposes a technique to estimate the distance between an object and a rolling shutter camera using a single image. The implementation of this technique uses the principle of the rolling shutter effect RSE , a distortion within the rolling-shutter-type camera. The proposed technique has a mathematical strength compared to other single photo-based distance estimation methods that do not consider the geometric arrangement. The relationship between the distance and RSE angle was derived using the camera parameters focal length, shutter speed, image size, etc. Mathematical equations were derived for three different scenarios.
