Abstract:
1. A system for creating a higher resolution still image from multiple video images having a lower resolution, the system including a processor and one or more computer-storage media and comprising: a sampling mechanism for extracting multiple images captured by a video recording device, wherein each of the multiple extracted images comprises at least a portion of a video frame, and wherein each of the images comprises the same area of interest, the sampling mechanism intelligently selecting multiple images captured by the video image capturing device by determining a difference between images and selecting consecutive images having a smallest difference; an analysis module for determining if the extracted images can be combined into an image comprising a resolution that is higher than the resolution of each of the extracted multiple images, wherein if the extracted images cannot be combined into the higher resolution image the sampling mechanism extracts additional images captured by the video recording device; a stacking module for stacking the multiple extracted images to create a single higher resolution still image, wherein the still image comprises a combination of the multiple extracted images, and further wherein the still image has a higher resolution than any one of the selected images; and an output mechanism having image output tools for outputting the single higher resolution still image, wherein the high resolution still image has a resolution that is equal to a resolution of one of the selected images multiplied by a square root of the total number of multiple images selected.
