“Privid” could help officials gather secure public health data or enable transportation departments to monitor the density and flow of pedestrians, without learning personal information about people. Rachel Gordon | MIT CSAIL Surveillance cameras have an identity problem, fueled by an inherent tension between utility and privacy. As these powerful little devicesContinue Reading

 All-pixel Autofocus? Autofocus on smartphone cameras in general takes phase difference detection.* This means that some pixels on the sensor are dedicated to the detection of phase differences. With this method, the image signal must compensate the areas corresponding to the detection pixels. However, too many detection pixels make itContinue Reading

Sony Semiconductor Solutions Corporation (“Sony”) has succeeded in developing the world’s first*1 stacked CMOS image sensor technology with 2-Layer Transistor Pixel. Whereas conventional CMOS image sensors’ photodiodes and pixel transistors occupy the same substrate, Sony’s new technology separates photodiodes and pixel transistors on different substrate layers. This new architecture approximately doubles*2 saturationContinue Reading

IntroductionThere is a clear trend and market need for high-power transmission over cable. Power over HDBaseT (POH) enablesthe transfer of DC power in conjunction with data signals over a single Ethernet cable to a distance of up to 100meters (m). The POH standard is based on the IEEE 802.3at standardContinue Reading

 Last month we posted a blog about HDBaseT that explained the application and how testing isn’t really any different since standards-based Category 5e, 5 or 6A will support it. But maybe you’ve also heard about power over HDBaseT, or POH, and you’re wondering how that differs from power over Ethernet (PoE). AContinue Reading

by Molly Sharlach, Princeton University Micro-sized cameras have great potential to spot problems in the human body and enable sensing for super-small robots, but past approaches captured fuzzy, distorted images with limited fields of view. Now, researchers at Princeton University and the University of Washington have overcome these obstacles with anContinue Reading

By: Ángel Díaz In every age, police forces gain access to new tools and technologies that may advance their mission to prevent and combat crime. The deployment of new technologies requires an understanding of their impacts on the fundamental rights of the communities that police serve and the development ofContinue Reading

Faster than the Human Eye! Higher Speed with Column-parallel A/D Conversion and Reducing Noise The key to increased speed of Sony’s CMOS Image Sensor can be found in parallel signal processing. CMOS sensors have analog-digital (A/D) conversion circuits that convert analog pixel signals into digital signals (Figure 1). Speed isContinue Reading
