System and method for viewing digital visual content on a device

摘要

A system and method for viewing material displayed on an electronic device. When a user desires to view a document, only a portion of which is viewable on a display at a given moment, the portion is displayed on the display as a primary image. A secondary image is then generated, with the secondary image including the portion and additional material of the document not part of the primary image. The secondary image is superimposed over the primary image on the display when a user scrolls through the document such that both the secondary image and the primary image are visible to the user.

主权项

1. A method comprising:
causing display of a zoomed-in portion of a document on a display as a primary image, wherein at least an additional portion of the document is not represented by the primary image at a given moment; generating a secondary image, the secondary image including the zoomed-in portion and at least the additional portion of the document, wherein the secondary image: a) is a zoomed-out view of the document, b) indicates a location of the primary image with respect to the document, and c) is smaller than the primary image; causing simultaneous display of the secondary image and the primary image on the display such that both the secondary image and the primary image are visible to a user and the secondary image covers only part of the primary image; in response to a scrolling of the primary image, causing a position of the secondary image to change relative to the primary image based on a direction of the scrolling such that at least a segment of the primary image previously covered by the secondary image is uncovered, wherein the at least one segment is identified based on the scrolling direction; altering the primary image such that at least a part of the additional portion, previously not represented by the primary image, is visible to the user on the primary image; and automatically adjusting the secondary image to indicate the location of the primary image with respect to the document based on the altered primary image.
