Claim:
A display device comprising: a source of an original image; a display; a user input system adapted to generate a signal in response to a user input action, wherein the user input action is not directional in that there is no apparent correlation between a direction of movement of user input controls and a location of a designated portion of the original image; and a controller adapted to determine a set of portions of the original image, the set of portions determined based at least on a frequency analysis of the original image to identify areas of the original image that are in focus and the set of portions defined corresponding to each of the identified in focus areas in the image, the set of portions including at least one portion having less than all of another portion, each portion including less than all of the original image and with the set having at least one portion that is non-central with respect to the original image and to successively designate a different one of a set of portions of the original image in response to the signal and adapted to cause the display to present a portion evaluation image showing the currently designated portion of the original image and to determine an area of importance in the original image based upon the currently designated portion; wherein each portion evaluation image shows the currently designated portion having a magnification, that is greater than the magnification that the currently designated portion has when the currently designated portion is presented as a part of the original image.
