Abstract
An improved automatic image capture system for an intelligent mobile device having a camera guides a user to position the camera so only a single image needs to be automatically captured. A trapezoidal view finder on a display of the intelligent mobile device may be used to orient the camera with respect to a target document so there is an appropriate pitch and roll angle between the camera and the target document to avoid shadows caused by the camera or user. Further the user is guided to maximize the occupancy of the view finder with the document so that the document is maximized within the view finder. When all requisite conditions are satisfied, the camera automatically captures the image of the document for post-processing.
Claims20
A method of automatic image capture of a target document using an intelligent mobile device having a camera comprising the steps of:
- showing a view finder on a display of the intelligent mobile device;
- guiding a user to maximize occupancy of the view finder with an image of the target document as a first condition;
- and
- automatically capturing the target document image for post-processing when the occupancy is maximized;
- wherein a shape of the view finder comprises a trapezoidal shape such that when a preferred pitch and roll angle of the camera with respect to the target document is achieved, the camera is tipped back from vertical and there is no shadow from the camera or user within the view finder.
A method of automatic image capture of a target document using an intelligent mobile device having a camera comprising the steps of:
- showing a trapezoidal view finder on a display of the intelligent mobile device;
- guiding a user of the intelligent mobile device to orient the camera at an appropriate pitch and roll angle with respect to the target document so an image of the target document has approximately the same trapezoidal shape on the display as the trapezoidal view finder and so that the camera and user do not cast a shadow on the target document image;
- and
- automatically capturing the target document image for post-processing when the target document image satisfies required conditions within the trapezoidal view finder.
