摘要： Disclosed are a pixel unit, and an imaging method and apparatus thereof. The pixel has a first and a second pixel sub-portion each comprising one or more photodiodes; one or more transfer transistors each coupled to a floating diffusion, for transferring the charges generated by the one or more photodiodes in response to incident light during an exposure period and accumulated in the photodiode during said exposure period respectively to the floating diffusion; a reset transistor; and a source follower transistor coupled to the floating diffusion for amplifying and outputting the pixel signal of the floating diffusion. In some embodiments, the pixel further includes a capacitor and a gain control transistor.
