摘要： An image sensor and a method for driving a pixel array in the image sensor are to prevent unnecessary power consumption by controlling transistors contained in a unit pixel. The unit pixel contains a transfer transistor, a reset transistor, a drive transistor and a select transistor. Under a correlated double sampling, within a predetermined period after the reset transistor is turned off, the select transistor is turned on to output a reset voltage level transferred from a voltage source as a unit pixel output signal through the drive transistor. As a result, the voltage source is not directly coupled to an output of the unit pixel to thereby effectively reduce unwanted power consumption and enhance the resulted picture quality.
