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.
Claims10
An image sensor comprising:
- a unit pixel configured to use a first power voltage;
- and
- a decoder configured to use the first power voltage and a second power voltage;
- wherein:
- the unit pixel includes a reset transistor configured to receive a reset signal;
- the second power voltage is different from the first power voltage;
- and
- the decoder includes a first output terminal configured to provide the reset signal, receive a first signal generated from the second power voltage, and responsively generate the reset signal from the first power voltage.
A method for sensing an image, the method comprising:
- providing a first power voltage to a unit pixel, wherein the unit pixel includes a reset transistor;
- providing a second power voltage to a decoder, wherein the second power voltage is different from the first power voltage and the decoder includes a first output terminal;
- generating, at the decoder, a first control signal from the second power voltage;
- receiving the first control signal at the first output terminal;
- generating, at the first output terminal, a reset signal from the first power voltage;
- and
- receiving the reset signal at the reset transistor.
