Contact Image Sensor

A Contact Image Sensor (CIS) is a type of imaging technology used in devices like scanners and copiers to capture images or documents. It works by placing the sensor directly in contact with the material being scanned. As the device moves over the document, the CIS converts the light reflected from the surface into electrical signals, creating a digital image. This technology is known for its compact size and efficiency, making it ideal for portable scanners and printers. CIS devices provide high-quality image capture with faster scanning times compared to traditional technologies.
