1. An imaging system comprising:
an electronic shutter operable in a first state with a first transparency and a second state with a second transparency that is lower than the first transparency;
an image sensor having an array of imaging pixels, wherein the image sensor is configured to capture a first image while the electronic shutter is in the first state and capture a second image while the electronic shutter is in the second state, wherein the image sensor if formed in an image sensor package, and wherein the electronic shutter is a package cover for the image sensor package; and
image processing circuitry configured to generate a single high dynamic range image using the first and second images, wherein generating the single high dynamic range image using the first and second images comprises combining the first and second images using at least some of the data from each one of the first and second images.
