Image SensorsImage sensors are sensors that are used to capture images. They are an essential component of cameras and other imaging devices, and are typically made up of a grid of light-sensitive pixels that convert light into electrical signals.
Image sensors can be classified according to the type of technology they use to convert light into electrical signals. The most common types of image sensors are charge-coupled devices (CCDs) and complementary metal-oxide-semiconductor (CMOS) sensors. CCD sensors are more sensitive and have a higher image quality, but are also more expensive and consume more power. CMOS sensors, on the other hand, are less expensive and more power-efficient, but have lower image quality.
Image sensors are used in a wide variety of applications, including photography, machine vision, security, and medical imaging. They are also used in smartphone cameras, webcams, and other consumer electronics devices.
In addition to capturing still images, image sensors can also be used to capture video. This is done by rapidly capturing a series of still images and then playing them back in sequence to create the illusion of motion. Image sensors can also be used in conjunction with other sensors, such as infrared sensors, to capture images in different lighting conditions or to detect objects in the dark.
