Abstract:
1. A computer-implemented method for displaying a portion of a high-resolution image in the context of a base-resolution image, wherein one or more processors are programmed to perform the steps comprising: receiving a request to view an image at a client device; sending a request to a server over a network for a base-resolution image that corresponds to the requested image; receiving the base-resolution image from the server over the network; displaying the base-resolution image on a display of the client device; receiving a request to display an area of interest of the base-resolution image in high resolution; sending a request to the server over the network for a high-resolution image that corresponds to the base-resolution image; receiving the high-resolution image from the server over the network; displaying a portion of the high-resolution image corresponding to the area of interest as an overlay of the base-resolution image at a location that corresponds to the area of interest, wherein the overlay comprises a virtual lens; tracking movements of a cursor controlled by a pointing device over the base-resolution image at the client device; moving the virtual lens with respect to the base-resolution image based on a location of the cursor relative to the base-resolution image; and updating the portion of the high-resolution image displayed by the virtual lens based on the location of the cursor relative to the base-resolution image.
