1. A method of capturing an image with an electronic camera having a shutter for selectively allowing light to reach an image sensor and readout circuitry for selectively reading out pixel data from the image sensor, the method comprising: opening the shutter; allowing light to reach the image sensor for a first exposure period; preserving pixel data captured during the first exposure period; allowing light to reach the image sensor for a second exposure period; reading out pixel data captured during the first exposure period while allowing light to reach the image sensor for the second exposure period; and, reading out pixel data captured during the second exposure period.
