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 10):
An image sensor comprising:\n pixels each including first and second photodiodes, the pixels each configured to output a reset output, a first output and a second output sequentially such that the first output is output by the first photodiode and the second output is output by the first and the second photodiode; a ramp voltage generator configured to generate a ramp voltage having a first gain such that a slope of the ramp voltage decreases according to a ramp clock; a correlated double sampler configured to compare the ramp voltage with each of the reset output, the first output and the second output, and to output a comparison signal based on a result thereof; a counter configured to count the comparison signal according to a counter clock to output a digital signal; a digital scaler configured to scale the digital signal such that the digital signal has a second gain; and a gain controller configured to control the first gain and the second gain to derive different user gains in different ones of a plurality of operation modes, the user gains each being a product of the first gain and the second gain, the plurality of operation modes including first to third operation modes requiring the user gains of x1, x2 and x4, respectively such that the second gain in the first operation mode is equal to half the second gain in the second operation mode.
