Abstract: In some implementations, a mobile device such as a smartphone or a tablet computer, will capture a substantially horizontal image when the user indicates initiation of an auto-leveling-image-capture mode and when an orientation detection component, such as a gyroscope, indicates that the mobile device is horizontal.

Abstract: Systems and methods for document management are presented. A virtual document, irrespective of a number of pages in the virtual document, may be transferred to a device via a network within a time period similar to or approximately equal to a time period to transfer a single page document. The systems, database structures, and methods described herein can allow for the management of a document similar to that of a file system, by allowing each individual page of a multi-page document to be stored and updated individually. In some embodiments, multi-page image documents may be stored at a page level, that is, each page of a multi-page image document may be individually stored and individually accessed, allowing for a random access of any page within a multi-page image document without a need to access any other pages of the multi-page image document.
