A Simplified Model for the Rolling Shutter Based Camera in Optical Camera Communications [PDF]
, 2019 A simplified model of the camera for optical camera communications (OCC) based on the rolling shutter effect is proposed and experimentally verified. In OCC, the key parameters are the exposure time, which is proportional to the DC gain and inversely ...

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

Shuffled rolling shutter for snapshot temporal imaging
Optics 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
