Abstract: An image sensor is provided. The image sensor includes a pixel configured to generate a reset signal and an image signal, a comparator configured to compare the reset signal with a reference signal and generate a first comparison signal, a counter configured to generate a first count value corresponding to the reset signal based on a clock signal and the first comparison signal, and a reference signal generator configured to generate the reference signal which changes between a first level corresponding to a maximum reset count value of the counter and a second level corresponding to a minimum reset count value of the counter during a reset signal period.

Abstract: An image sensor is disclosed. The image sensor includes a plurality of pixels, a switch circuit coupled to the pixels and configured to substantially simultaneously output signals output only from pixels having similar characteristics among the pixels in response to a control signal; and a comparison circuit configured to convert the signals output from the switch circuit into digital signals. The pixels having similar characteristics are located across among the plurality of pixels.

Abstract: An image processing device includes a switch signal generator, an amplifier, a ramp generator, and an attenuation control circuit. The switch signal generator generates switch control signals based on a level of an image signal that corresponds to a pixel signal output from a pixel. The amplifier includes a first input terminal and a second input terminal. The ramp generator generates a ramp signal. The attenuation control circuit adjusts an arrangement of capacitors according to the switch control signals to control whether to attenuate each of the pixel signal and the ramp signal, and transmits signals generated as a result of the adjusted arrangement to the first input terminal and the second input terminal.
