10. The display device of claim 9 , wherein the one or more image attributes are selected from at least one of: (i) user input; (ii) a computed quality metric of the one or more respective images of the video stream; and (iii) an audio element from the video stream.

11. The display device of claim 10 , wherein the quality metric is computed based on a plurality of attributes of the respective images of the video stream, the plurality of attributes comprising: (i) an image sharpness; (ii) an image brightness; (iii) an image contrast; (iv) an image color; (v) a presence of at least one human face; and (vi) a number of open human eyes.

12. A computer-implemented method for generating graphical user interface of a display device, the method comprising:

displaying a first image from a video stream in a first display area of a display, the first image having an associated capture time;

displaying a first plurality of images from the video stream in a second display area of the display, wherein each image of the first plurality of images is associated with a corresponding capture time prior to the capture time of the first image;

displaying a second plurality of images comprising a plurality of images from the video stream in a third display area of the display, wherein each image of the second plurality of images is associated with a corresponding capture time subsequent to the capture time;

displaying a user input element operable to capture the first image as a snapshot image, the snapshot image being a still image of the first image in the first display area, the snapshot image being displayed in a fourth display area of the display;

programmatically scanning and capturing, based on at least one image attribute and by operation of one or more computer processors, one or more snapshot images corresponding to respective images selected from the video stream; and

displaying the one or more captured snapshot images in the fourth display area of the display.

13. The computer-implemented method of claim 12 wherein the first side is a top side of the first display area and the second side is a bottom side of the first display area.

14. The computer-implemented method of claim 13 wherein the fourth display area is adjacent to a third side of the first display area.

15. The computer-implemented method of claim 14 further comprising a user input button configured to display the first image in the fourth display area in response to actuation of the user input button.

16. The computer-implemented method of claim 12 wherein the plurality of sequential images associated with capture times subsequent to the capture time are characterized by decreasing image size as a function of capture time.

17. The computer-implemented method of claim 12 , wherein the one image attributes are selected from at least one of: (i) user input; (ii) a computed quality metric of the one or more respective images of the video stream; and (iii) an audio element from the video stream.

18. The computer-implemented method of claim 17 , wherein the quality metric is computed based on a plurality of attributes of the respective images of the video stream, the plurality of attributes comprising: (i) an image sharpness; (ii) an image brightness; (iii) an image contrast; (iv) an image color; (v) a presence of at least one human face; and (vi) a number of open human eyes.

19. A computer program product to generate a graphical user interface on a display device, comprising:

a computer-readable storage medium having computer-readable program code embodied therewith, the computer-readable program code comprising:

computer-readable program code configured to display a first image from a video stream in a first display area of a display, the first image having an associated capture time;

computer-readable program code configured to display a first plurality of images from the video stream in a second display area of the display, wherein each image of the first plurality of images is associated with a corresponding capture time prior to the capture time of the first image;

computer-readable program code configured to display a second plurality of images comprising a plurality of images from the video stream in a third display area of the display, wherein each image of the second plurality of images is associated with a corresponding capture time subsequent to the capture time;

computer-readable program code configured to display a user input element operable to capture the first image as a snapshot image, the snapshot image being a still image of the first image in the first display area, the snapshot image being displayed in a fourth display area of the display;
