Understanding Digital Camera Sensors (How Do They Work?)

WebApr 25, 2024 · The goal of an image sensor is to convert the light focused by our lens into electrical signals that can be processed by a CPU into a digital image. We all understand the term pixels. It's fundamental to the image quality of our cameras. But what is a pixel in relation to a camera sensor? Each pixel is an individual photodetector. WebThe function of a photoelectric sensor is to use light to detect the presence or absence of an object. A photoelectric sensor consists of the sensor, control unit, and output. The source is a light-emitting diode that emits a powerful beam of infrared or visible light.
