ABSTRACT:
A method for capturing multiple sets of image data with an electronic camera having a shutter and an electronic shutter for selectively allowing light to reach an image sensor comprises opening the shutter and the electronic shutter, allowing light to reach the image sensor for a first exposure time, closing the electronic shutter, reading out pixel data captured during the first exposure time, allowing light to reach the image sensor for a second exposure time, and, reading out pixel data captured during the second exposure time. The method may be used to obtain multiple differently exposed images of a scene for combination into a high dynamic range image.
