Abstract:
Provided are image sensors. An image sensor includes a pixel array comprising pixels configured to output signal voltages, each of the pixels comprising first and second photodiodes, first and second transfer transistors connected to the first and second photodiodes, respectively, and a floating diffusion node to which the first and second transfer transistors are connected; a ramp voltage generator configured to generate a ramp voltage that decreases with a slope according to a ramp clock to have a first gain; a correlation double sampler (CDS) configured to compare the ramp voltage with the signal voltages to output a comparison signal; a counter configured to count the comparison signal according to a counter clock to output a digital signal; and a digital scaling unit configured to scale the digital signal to have a second gain.

Claim (Index 1):
An image sensor comprising:\n a pixel array including pixels configured to output signal voltages, each of the pixels including first and second photodiodes and first and second transfer transistors, the first and second transfer transistors each connected between respective ones of the first and second photodiodes and a floating diffusion node; a ramp voltage generator configured to generate a ramp voltage having a first gain such that a slope of the ramp voltage decreases based on a ramp clock; a correlation double sampler (CDS) configured to compare the ramp voltage with signal voltages to output a comparison signal; a counter configured to count the comparison signal according to a counter clock to output a digital signal; and a digital scaler configured to scale the digital signal such that the digital signal has a second gain.
