ABSTRACT:
An image sensor an image sensor includes an image sensing element which converts incident light into an analogue signal, a voltage generator which includes a variable resistor circuit and which generates a ramping voltage, where a slope of the ramping voltage is variable and corresponds a resistance value of the variable resistor circuit, a converter which converts a voltage of the analogue signal into a digital signal using the ramping voltage generated by the voltage generator, and a controller which controls the resistance value of the variable resistance circuit.
