A CMOS image sensor is a complex system that deals with physics on an atomic level all the way up to the mechanical requirements of packaging into a device assembly. Teams who are designing a new CMOS sensor should consider the following aspects: Photonic Design The behavior of the photodiode...
Photogrammetry is the process of taking reliable measurements from photographs. It has been with us in some form for centuries and has helped shape our understanding of things like the Earth’s surface. Today, it plays a vital role in many industries. So
Exposure is one of the most fundamentalphotography terms. When you take a picture, you press the shutter button to open a camera’s aperture, and light streams in, triggering a response from a sensor. Exposure is the amount of light that reaches your camera’s sensor, creating visual data ...
While focal length itself refers to the field of view of a lens, f-stop is about how much light you allow to hit the sensor via the aperture opening. The aperture is the hole in the middle of the lens, made up of rotating blades that open to let in light when you press the ...
Eye tracking is a sensor technology that captures and translates eye movements into insights about human behavior — its potential applications are vast. The value of eye tracking At it’s center, eye tracking technology measures where someone is looking. By using cameras to detect eye movements,...
While your camera's built-in light meter measures light sensitivity, photographers refer to ISO as the "speed" of the film or sensor. At high sensitivity, more light is sensed within a given period of time than at low sensitivity, so high sensitivity is considered faster. Unlike aperture, ...
prevent any IR light from falling on the sensor. During the night, the IR cut filter is removed mechanically to allow IR light to come in to assist with low light imaging. However, this mechanical component leads to wear and tear over time and adversely affects the l...
Related:What's the Difference Between a Full Frame and Crop Sensor Camera? On a full-frame camera, a normal lens is considered to have a focal length of 50mm. This was set by the creator of the Leica camera system, Oskar Barnack, pretty much arbitrarily. In reality, any lens with a ...
The exposure of the gray card will be made to be middle gray too, which happens to be about correct then, because the card IS middle gray. It is not 50% intensity, but 18% which is how the human eye and brain decides middle gray. And most typical scenes do average about middle ...
A continuous glucose monitor (CGM)uses a sensor to check your child's blood sugar level. The sensor is placed on your child's abdomen or arm. A transmitter on the sensor gets a glucose reading. CGM data may be linked to an insulin pump, if needed. The data will help your child's ...
