Abstract
An imaging system may include an electronic shutter. The electronic shutter may be positioned between an image sensor and a lens module or may be integrated as a package cover for the image sensor. The electronic shutter may selectively attenuate incident light that passes to the image sensor. To increase the dynamic range of the imaging system, the electronic shutter may have a first transparency while a first image is captured by the image sensor and a second, different transparency while a second image is captured by the image sensor. The first and second images are subsequently combined to form a single high dynamic range image. The electronic shutter may be controlled at a global level, at a sub-array level, or at a pixel level.
