System and method for dynamic zoom to view documents on small displays
First Claim
1. A method for providing a source document image for display, comprising:
- identifying a plurality of sections of the source document image, and at least one characteristic of each of the sections;
associating a display zoom factor with each of the identified sections based upon the at least one characteristic of each section;
creating an adjusted zoom image of at least a selected section for display in response to the display zoom factor for the selected section;
sending the adjusted zoom image of the selected image section for display; and
displaying the adjusted zoom image.

Abstract
A system and method for dynamic zoom adjustment based, in part, upon: the raster data in the user selected local area is disclosed; and/or the knowledge of a prevailing font size in a user selected region such that the text in that region is enlarged to be just readable. To achieve this, the detail in the local area is examined and a zoom factor is calculated that depends on the image detail and/or the viewing screen resolution. A document server may be employed to develop the information needed to enable this functionality. In one embodiment, the information is developed by RIPping the document, and then storing a spatial map of localized details (e.g., font sizes at several display resolutions) to automatically adjust a zoom level or factor and thereby facilitate navigation and reading.

11. A document image display system, comprising:
-
a source document image created from a rasterized image; a server for processing the source document image and identifying a plurality of sections of the source document, and at least one characteristic of each of the sections; memory for storing the at least one characteristic for each of the plurality of sections; and a computing device, including a display associated therewith, for displaying at least a section of the source document, wherein the section is displayed as an image received from the server, and where said image is created for display using a display zoom factor based upon the at least one characteristic of the section. - View Dependent Claims (12, 13, 14)

15. A method for providing a source document for display on a handheld device, comprising:
-
identifying, with a server, a plurality of sections of the source document and for each section determining at least one characteristic representative of each of said sections; for each identified section, associating at least one display zoom factor therewith based on the at least one characteristic representative of said section; sending a first document image, at a first zoom level, from the server to a handheld device for display thereon; selecting, using the handheld device, at least one of said sections of said document for zooming; transmitting, from said handheld device to the server, information identifying the selected section; creating on the server, in response to the information identifying the selected section, a second document image including at least a portion of the selected section at the display zoom factor; and sending the second document image from the server to the handheld device. - View Dependent Claims (16, 17, 18, 19, 20)
