Rolling shutter distortion correction

SPIE Proceedings, 2005
As opposed to the global shutter, which starts and stops the light integration of each pixel at the same time by incorporating a sample-and-hold switch with analog storage in each pixel, the electronic rolling shutter found in most low-end CMOS image sensors today collects the image data row by row, analogous to an open slit that scans over the ...

Performance of rolling shutter and global shutter camera in optical camera communications

2015 International Conference on Information and Communication Technology Convergence (ICTC), 2015
Optical Camera Communication (OCC) is considered as an extension of IEEE 802.15.7 specification by same communication channel. Different with another technique, Optical Camera Communication used image sensor for receiver, so the characteristic of image sensor will effect on the operation and performance.

Unified Video Reconstruction for Rolling Shutter and Global Shutter Cameras

IEEE Transactions on Image Processing
Currently, the general domain of video reconstruction (VR) is fragmented into different shutters spanning global shutter and rolling shutter cameras. Despite rapid progress in the state-of-the-art, existing methods overwhelmingly follow shutter-specific paradigms and cannot conceptually generalize to other shutter types, hindering the uniformity of VR ...

Deep end-to-end rolling shutter rectification

Journal of the Optical Society of America A, 2020
CMOS sensors employ a row-wise acquisition mechanism while imaging a scene, which can result in undesired motion artifacts known as rolling shutter (RS) distortions in the captured image. Existing single image RS rectification methods attempt to account for these distortions by using either algorithms tailored for a specific class of scenes that ...

Video stabilization and rolling shutter distortion reduction

2010 IEEE International Conference on Image Processing, 2010
This paper presents an algorithm that stabilizes video and reduces rolling shutter distortions using a six-parameter affine model that explicitly contains parameters for translation, rotation, scaling, and skew to describe transformations between frames. Rolling shutter distortions, including wobble, skew and vertical scaling distortions, together with

Motion and velocity estimation of rolling shutter cameras

Proceedings of the 9th European Conference on Visual Media Production - CVMP '12, 2012
Most modern camera designs based on CMOS sensors do not have a global, but a rolling shutter that exposes the lines of the sensor at different times. This leads to distortions under camera or object motion and affects computer vision techniques. This article introduces the use of a linear velocity model for camera motion and estimates these additional ...

Rolling shutter super-resolution in burst mode

2016 IEEE International Conference on Image Processing (ICIP), 2016
Capturing multiple images using the burst mode of handheld cameras can be a boon to obtain a high resolution (HR) image by exploiting the subpixel motion among the captured images arising from handshake. However, the caveat with mobile phone cameras is that they produce rolling shutter (RS) distortions that must be accounted for in the super-resolution

HDR Recovery Under Rolling Shutter Distortions

2015 IEEE International Conference on Computer Vision Workshop (ICCVW), 2015
Preserving the high dynamic irradiance of a scene is essential for many computer vision algorithms. In this paper, we develop a technique for high dynamic range (HDR) reconstruction from differently exposed frames captured with CMOS cameras which use a rolling shutter (RS) to good effect for reducing power consumption.
