Abstract
There is provided an image sensor including a BJT pixel circuit and a light source. The BJT pixel circuit adopts a reset settling time of a base-emitter voltage of a bipolar junction transistor before the light source is turned on to illuminate light. The light source provides light energy to the BJT pixel circuit within a pre-flash time and an exposure time. The reset settling time, the pre-flash time and the exposure time are changed with light energy detected by the BJT pixel circuit with a negative relationship.
