Abstract: A method of capturing a digital image with a digital camera includes determining a first exposure level for capturing an image based on a first luminance level of the image, determining a second exposure level for capturing the image based on a threshold exposure level of the image, configuring an exposure level of a sensor of the digital camera based on the second exposure level, capturing the image as a digital image, and adding a non-linear digital gain to the digital image based on a difference between the first exposure level and the second exposure level.
