IMAGE SENSOR AND CAMERA SYSTEM INCLUDING IMAGE SENSOR

摘要

PURPOSE: An image sensor and a camera system including the same are provided to implement high sensitivity without decreasing frame rate and to increase SNR. CONSTITUTION: An ADC(Analog to Digital Converter)(300) operates an operation mode. The ADC performs digital conversion through a reference signal. The ADC adds a digital-converted value. The ADC generates a digital signal. A controlling unit(400) controls an operation of a pixel array, a reference signal generating unit, and the ADC.
