Imaging method with an image sensor with a high dynamic range

摘要

The method involves controlling conduction of a transistor (N1) to impose an initialization voltage on terminals of a photodetector element. The conduction of the transistor is interrupted to start an exposure period in which the photodetector element accumulates charge carriers. Conduction of another transistor (N2) is controlled after interrupting conduction of a third transistor (N3) during the exposure period to store a voltage level of the photodetector element in a storage unit e.g. capacitor. The voltage level stored in the storage unit is read.
