ABSTRACT:
An image sensor for obtaining a digital image data by using a correlated double sampling method unrelated to an intensity of inputted light includes a pixel array including N×M unit pixels; a reset voltage check block for receiving each reset signal outputted from each unit pixel and comparing a level of each reset signal with a minimum level of a preferable reset signal to thereby generate a reset compensation control signal; a reset voltage compensation block for compensating the reset signal outputted from each unit pixel in response to the reset compensation control signal to generate a compensated reset signal; and an analog to digital converter for deriving an analog image data by using a data signal outputted from the pixel array and the compensated reset signal to convert the analog image data into the digital image data.
