Did you know?
WebIn a camera system, the image sensor receives incident light (photons) that is focused through a lens or other optics. Depending on whether the sensor is CCD or CMOS, it will transfer information to the next stage as either a voltage or a digital signal. CMOS sensors convert photons into electrons, then to a voltage, and then into a digital ... Web21 de fev. de 2024 · It works by allowing light (photons) to pass through a semiconductor material, which creates an electrical current. This current is then passed through an amplifier circuit and converted into a usable voltage or digital signal, depending on the type of light sensor being used.
