Abstract

Disclosed are an image sensor and an image sensing method. The image sensor includes a first pixel circuit. The first pixel circuit includes a first driving transistor, a first selection transistor, a first transfer transistor, a first reset transistor and a first sensing unit. A control terminal of the first selection transistor is used for receiving a first selection signal. A control terminal of the first transmitting transistor is used for receiving a first transmitting signal. The image sensing method includes the following steps: receiving a first reset signal during a reset period through a control terminal of the first reset transistor; and receiving a first ramp signal during a sensing period through a control terminal of the first reset transistor.
