Summary: | An image sensor includes: a pixel outputting a pixel signal; a ramp voltage generation circuit suitable for generating a ramp voltage that changes at a first slope in a first section and generating the ramp voltage that changes at a second slope having a greater absolute value than the first slope in a second section following the first section; an operation amplifier suitable for comparing the pixel signal with the ramp voltage during the first section and the second section; and a counter circuit suitable for generating a digital code corresponding to the pixel signal in response to an output of the operation amplifier. |
