image sensor

An image sensor is a device that captures light to create images in digital cameras and smartphones. When you take a photo, light from the scene hits the sensor, which converts it into electronic signals. These signals are then processed to produce a digital image. There are two main types of image sensors: CCD (Charge-Coupled Device) and CMOS (Complementary Metal-Oxide-Semiconductor). Each type has its strengths, with CMOS sensors being more common today due to their efficiency and lower power consumption. Overall, image sensors are crucial for converting the visual world into the digital images we see on screens.
