1. A method of combining image data from multiple frames to enhance one or more parameters of digital image quality, comprising using a processor and at least one digital image acquisition system including a lens and an image sensor in: acquiring a first image at a first exposure duration; acquiring a second image at a second exposure duration shorter than the first exposure duration and at a time just before, just after or overlapping in time with acquiring the first image, such that said first and second images comprise approximately a same first scene, and whereby the second image is relatively sharp and under-exposed and the first image is relatively well-exposed and less sharp than the second image; extracting brightness or color information, or both, from the first image; applying to the second image the brightness or color information, or both, extracted from the first image to generate an enhanced version of the second image enhanced in terms of brightness or color quality, or both; displaying, storing, transmitting, or streaming the enhanced version of the second image; acquiring a third image at or near said first exposure duration when a predetermined number of multiple frames has been recorded since the acquiring of the first image; acquiring a fourth image at or near said second exposure duration and at a time just before, just after or overlapping in time with the third image, such that said third and fourth images comprise approximately a same second scene different from or same as the first scene; extracting brightness or color, or both, from the third image; applying to the fourth image the brightness or color information, or both, extracted from the third image to generate an enhanced version of the fourth image enhanced in terms of brightness or color quality, or both; and displaying, storing, transmitting, or streaming the enhanced version of the fourth image.
