Abstract
Generating an image with an imaging system includes capturing a first sub-image during a first exposure with a first pixel subset of an image sensor of the imaging system, capturing a second sub-image during a second exposure with a second pixel subset of the image sensor, capturing a third sub-image during a third exposure with a third pixel subset of the image sensor, and capturing a fourth sub-image during a fourth exposure with a fourth pixel subset of the image sensor. The first, second, third, and fourth exposures have different durations. A preferred exposure is selected from between the first, second, third and fourth exposures by analyzing the first, second, third, and fourth sub-images. Then, a full-resolution image is captured at the preferred exposure. An HDR image is generated based on the full-resolution image and the sub-images.
