Decoding CMOS Rolling-Shutter Pattern in Translational or Rotational Motions for VLC

open access: yesIEEE Photonics Journal, 2019
We propose and demonstrate a CMOS rolling-shutter pattern decoding scheme based on two newly introduced schemes, named row grayscale redistribution and differential grayscale packet selection to improve the performance in decoding the CMOS rolling ...

Timing generator for 120fps CMOS image sensors on 0.13 μm CMOS technology [PDF]

open access: yes, 2017
Image clarity is an important criterion in digital imaging. However, typical rolling shutter type complementary metal-oxide semiconductor (CMOS) image sensors with frame rate of 30fps which is used for relatively slow speed image capture suffers from ...

Shuffled rolling shutter for snapshot temporal imaging

open access: yesOptics Express, 2022
We propose a modification to the rolling shutter mechanism found in CMOS detectors by shuffling the pixels in every scanline. This potential hardware modification improves the sampling of the space-time datacube, allowing the recovery of high-speed videos from a single image using either tensor completion methods or reconstruction algorithms often used

The Optical Bar Code Detection Method Based on Optical Camera Communication Using Discrete Fourier Transform

open access: yesIEEE Access, 2020
Optical camera communication (OCC) traditionally uses the bright and dark stripes of rolling shutter pattern captured by the complementary metal-oxide-semiconductor (CMOS) image-sensor to realize communication.

Fast Rolling Shutter Correction in the Wild

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2023
This paper addresses the problem of rolling shutter correction (RSC) in uncalibrated videos. Existing works remove rolling shutter (RS) distortion by explicitly computing the camera motion and depth as intermediate products, followed by motion compensation.

Beacon Jointed Packet Reconstruction Scheme for Mobile-Phone Based Visible Light Communications Using Rolling Shutter

open access: yesIEEE Photonics Journal, 2017
Mobile-phone based visible light communication (VLC) is an attractive method for optical wireless communication. However, the data rate is typically limited by the complementary metal–oxide–semiconductor image sensor frame rate and the ...

Direct Sparse Odometry with Rolling Shutter [PDF]

open access: yes, 2018
Neglecting the effects of rolling-shutter cameras for visual odometry (VO) severely degrades accuracy and robustness. In this paper, we propose a novel direct monocular VO method that incorporates a rolling-shutter model. Our approach extends direct sparse odometry which performs direct bundle adjustment of a set of recent keyframe poses and the depths

Analysis and Compensation of Rolling Shutter Effect [PDF]

open access: yesIEEE Transactions on Image Processing, 2008
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. In this paper, we propose
