Classification: CPC H  G | IPC G  H

Claim 15:
16. A method, comprising:
during a first mode of a pixel, when a first transistor and a second transistor that are coupled in parallel to a sensing unit are turned off, in response to a sensing voltage associated with light at a first terminal of a third transistor, generating a first transfer voltage at a second terminal of the third transistor;
generating a first auxiliary voltage associated with the sensing voltage at a first terminal of a fourth transistor, wherein a second terminal of the fourth transistor is coupled to the second terminal of the third transistor at a first node;
turning on a fifth transistor; and
outputting a first data signal through the fifth transistor and a sixth transistor by switching a seventh transistor coupled between a supply voltage terminal and the first node, wherein a first terminal of the sixth transistor is coupled to the first node and a second terminal of the sixth transistor is coupled to the fifth transistor.
