Abstract
A method of image capture helps avoid saturation in digital imaging. In one implementation, the method includes capturing a first digital image of a target using an electronic array light sensor, and identifying one or more saturated pixels in the first digital image. The method further includes identifying a region of interest in the first digital image, the region of interest encompassing the one or more identified saturated pixels. The method also includes capturing a second digital image of the target using the electronic array light sensor. The second digital image encompasses only the region of interest, and the second digital image is captured with a shorter exposure time than the first digital image. The first and second digital images may be combined into a high dynamic range image. Systems for digital imaging may be based on complementary metal oxide semiconductor (CMOS) or charge coupled device (CCD) sensors.
