Simulation of Rolling Shutter Acquisition in Optical Camera Communications [PDF]
2019 15th International Conference on Telecommunications (ConTEL), 2019 The rolling shutter (RS) acquisition mechanism performed by the majority of the digital cameras included in portable devices has been exploited to make receivers for visible light communications (VLC). They are able to decode signals of frequencies higher than the frame rate of the camera, which is a limitation when using global shutter sensors.

Low Memory Access Video Stabilization for Low-Cost Camera SoC
Sensors, 2022 Video stabilization is one of the most important features in consumer cameras. Even simple video stabilization algorithms may need to access the frames several times to generate a stabilized output image, which places a significant burden on the camera ...

Modelization and Characterization of a CMOS Camera as an Optical Real-Time Oscilloscope
IEEE Photonics Journal, 2020 Complementary Metal-Oxide Semiconductor (CMOS) camera sensors are embedded in many consumer electronics products: thanks to the Rolling Shutter (RS) readout mode, they can detect a time-varying light intensity, which is the key to realize Optical Camera ...

Adding Synchronization and Rolling Shutter in Multi-Camera Bundle Adjustment [PDF]
Procedings of the British Machine Vision Conference 2016, 2016 Multi-cameras built by fixing together several consumer cameras become popular and are convenient for applications like 360 videos. However, their self-calibration is not easy since they are composed of several unsynchronized and rolling shutter cameras.

400 m rolling-shutter-based optical camera communications link [PDF]
Optics Letters, 2020 In this Letter, we develop a novel technique, to the best of our knowledge, to increase the link span ( L s ) of a rolling shutter (RS)-based optical camera communications (OCC) system by reducing the spatial bandwidth of the camera in the out-of-focus regions.

Visible Light Communication Using Receivers of Camera Image Sensor and Solar Cell
IEEE Photonics Journal, 2016 We propose an electronic label and sensor system using visible light communication (VLC). The downlink signal is transmitted by a white-light light-emitting diode (LED) lamp that can provide lighting, VLC, and energy harvesting for mobile devices.
