Claim 7

A system including: a screen; and a computer including a computer program for digital image magnification on the screen, the program including computer executable commands that cause the computer to receive from a user an indication of a selected region of an original image on the screen, superimpose on the original image a floating plane region on the screen containing a magnified image of the selected region, wherein the floating plane region has an area larger than an area of the selected region and smaller than an area of the original image, such that the selected region of the original image is magnified and viewed while preserving the context of the selected region, superimpose on the original image a shadow region corresponding to the floating plane region, the shadow region corresponding to a shadow having the same dimensions of the floating plane region; move the selected region, move the floating plane region and dynamically update the magnified image as the selected region moves to preserve the context of the original image, and restore a portion of the image which was previously covered by the floating plane region; wherein the original image and the magnified image include moving video, and wherein the magnified image is partially transparent, allowing a user to distinguish at least a portion of the original image below the magnified image while at the same time being able to distinguish the magnified image; the program including executable commands to synchronize the refreshing of the floating plane with movement of the underlying image data of the video.

Claim 8

A system including: a screen; and a computer including a computer program for digital image magnification on the screen, the program including computer executable commands that cause the computer to receive from a user an indication of a selected region of an original image on the screen, superimpose on the original image a floating plane region on the screen containing a magnified image of the selected region, wherein the floating plane region has an area larger than an area of the selected region and smaller than an area of the original image, such that the selected region of the original image is magnified and viewed while preserving the context of the selected region, superimpose on the original image a shadow region corresponding to the floating plane region, the shadow region corresponding to a shadow having the same dimensions of the floating plane region; move the selected region, move the floating plane region and dynamically update the magnified image as the selected region moves to preserve the context of the original image, and restore a portion of the image which was previously covered by the floating plane region; wherein the original image and the magnified image include moving video, and wherein the magnified image is partially transparent, allowing a user to distinguish at least a portion of the original image below the magnified image while at the same time being able to distinguish the magnified image; the program including executable commands to synchronize the refreshing of the floating plane with movement of the underlying image data of the video.
