We extend the vision adaptation to the spectra dimension. In challenging lighting conditions, machine vision often yields low-quality results. In situations where particular spectral signatures carry critical information, adapting the spectral sensitivity of visions systems to match the predominant spectra of the surrounding environment can improve light capture and image quality. Here we report spectra-adapted vision sensors based on arrays of back-to-back photodiodes. The spectral sensitivity of these bioinspired sensors can be tuned to match either the broadband visible spectrum or a narrow band within the near-infrared spectrum by applying different bias voltages. The process of spectral adaptation takes tens of microseconds, which is comparable with the frame rate (around 100 kHz) of state-of-the-art high-speed cameras. The spectral adaptation increases the Weber contrast of the scene by over ten times, resulting in increased recognition accuracy (from 33% to 90%) of features when exposed to intense visible-light glare. https://lnkd.in/gNUTDQY3

Hola Technocrats!!! Have you ever wondered how your phone knows when its case is closed, or how a brushless motor in your drone spins so smoothly? The answer might surprise you: it's all thanks to a tiny sensor called the Hall effect sensor. 𝐖𝐡𝐚𝐭 𝐢𝐬 𝐢𝐭? The Hall effect sensor is a fascinating piece of technology that uses a principle called the Hall effect. When a magnetic field is applied to a conductor with current flowing through it, a voltage is created at right angles to both the current and the magnetic field. This voltage, known as the Hall voltage, is proportional to the strength of the magnetic field. So, the next time you interact with a device that uses magnets or senses position and movement, remember the silent hero behind the scenes: the Hall effect sensor, a testament to the ingenuity of human innovation. ----------------------------------------------------------- Share with your friends if you're an electronic enthusiast!!

🗞 Electronic News! 🗞 The Time-of-Flight sensor developed by Nuvoton is set to transform the way people and objects are recognized in a variety of indoor and outdoor settings. This breakthrough is made possible by Nuvoton's innovative pixel design and advanced distance calculation and image signal processor technology. By harnessing Nuvoton's proprietary CMOS image sensor pixel and CCD memory technology, the latest ToF sensor boasts four memories within each 5.6-square-micrometer pixel, surpassing the three memories found in traditional ToF sensors. This enhancement enables the sensor to achieve precise distance sensing by efficiently managing pulse light sources and capturing background light signals. As a result, it can accurately determine the position and shape of individuals and objects across different lighting conditions. #electricalengineering #electronics #embedded #embeddedsystems #electrical #computerchips Follow us on LinkedIn to get daily news: HardwareBee - Electronic News and Vendor Directory

Zooming... 1- Digital zoom: From Sony's specs of the Q1 sensor chip, you pretty much get that zooming is limited to 2x. Reason: no one knows how to model chromatic distortion. No one but us !... I reviewed Stanford's web site for Bayer pattern interpolation algos, only to find out no one took into consideration the image scale change between RGB. The Red image is bigger than Green, bigger than Blue, splitting edges and corners, creating 'false' colors, and interpolating the Bayer pattern using this false color data propagates the chromatic distortion to the entire image, before it is even used for feature extraction. 2x zooming from Sony means color accuracy at ½ pixel, we get 1/8, which means that our digital zooming could reach 8x... That is for our next set of patents Mechanical Zoom: I always left out key details about this, since according to ISO TC 172 on Optics and Photonics, it is the key technology missing for the widespread use of imagery: telemetry from a zooming lens. On top of chromatic distortion, and Bayer pattern bias, you have to know how and what parameters need to be re-calibrated once the zoom changes, how to achieve it, which would allow successive refining of telemetry, how a lens design could be optimized for this specific use... a major disrupter for military surveillance and targeting... We are likely to make our solution public faster then we wanted, since multiple asks from clients show a need to go beyond where current technology allows. 2 solutions... 1- digital zoom, bring accuracy and zoom from 2x to 8x with our optimization 2- mechanical zoom, for ultra high accuracy systems... for 10x and more We beat NASA... and Sony #digitalimaging #computervision #robotics #deepfake #surveillance #military
