An image sensor includes a pixel array including a plurality of pixels; a ramp signal generator configured to generate a ramp signal; a plurality of first attenuators with each first attenuator connected to a respective column of the plurality of pixels, and each first attenuator configured to receive a pixel signal from a respective pixel belonging to a selected row; a plurality of second attenuators with each second attenuator corresponding to a respective column, and each second attenuator configured to receive the ramp signal from the ramp signal generator; and a plurality of analog-to-digital converters configured to output digital signals by comparing first signals output from the plurality of first attenuators and second signals output from the plurality of second attenuators, in which each of the plurality of first attenuators and each of the plurality of second attenuators comprises a first capacitor and a second capacitor.

Image sensor and camera module including image sensor

An image sensor includes a pixel array including a plurality of pixels arranged in a matrix, each of the pixels including a microlens, a first photoelectric conversion element, and a second photoelectric conversion element, the first and second photoelectric conversion elements being arranged parallel with each other in a first direction below the microlens; and a row decoder configured to control a first image signal generated by the first photoelectric conversion element and a sum image signal generated by the first and second photoelectric conversion elements to be sequentially output from a first pixel in a first row of the pixel array during a first readout period, and to control a second image signal generated by the second photoelectric conversion element and the sum image signal to be sequentially output from a second pixel in a second row of the pixel array during a second readout period.
