Abstract
There is provided an image sensor capable of minimizing level variations of a control signal inputted to a unit pixel. The image sensor includes a plurality of unit pixels, each supplied with a first power voltage for converting an inputted signal into an electrical signal; and a control block supplied with a second power voltage for providing control signals to each unit pixel in order to stably operate each unit pixel, wherein the control block includes a conversion unit for outputting the control signals under the first power voltage, not the second power voltage.
