How Your Digital Camera Sensor Works A digital camera’s sensor collects light and converts that light into an image. It’s a small square positioned inside the camera body behind where the lens ...

At the heart of all digital cameras is an image sensor, which converts light information transmitted via a lens into an electrical signal that can then be stored and called up later by a computer ...

Professor Danielle George explains how a digital camera’s CMOS sensor captures an image, using balls and buckets to represent photons, electrons and capacitors.

The image sensor in that camera didn’t have much in common with the ones we use today, but you have to admit it is clever. Of course, 1975 was also the year Kodak developed a digital camera and ...

A pixel is the smallest component that makes up a digital image. The megapixel value you'll find written on your camera simply means how many pixels (or photo sensors) are on your image sensor.

How the latest digital-camera sensors create sharper color photographs.

However, CMOS sensors would eventually become more capable, and the video explains how it works. We’ve looked at image sensors before, too.

Software-based autofocus (known as passive autofocus) uses data from the image sensor to determine whether the image is in focus and adjusts the lenses to compensate.

Window sensors are a critical part of any home security system. Learn how they work so you can ensure this last line of defense is there when you need it.

The same person that created the sensor found in most cameras is behind a new Quanta Image Sensor with crazy low-light capabilities.
