Abstract
A contact image sensor is provided, including: a control unit configured to receive output pulses from an encoder, where the control unit includes a comparator configured to compare the output pulses with a preset scanning cycle stored in the register to obtain an illumination control signal; an illumination unit configured to illuminate an object to be detected based on the illumination control signal; a scanning unit configured to scan the object to be detected based on the scanning trigger signal to obtain a scanning signal; a data processing unit configured to process the scanning signal to obtain an initial scanning result; and a data output unit configured to obtain a target scanning result based on the initial scanning result and output the target scanning result based on the output trigger signal.
