INTERACTIVE USER INTERFACE FOR CAPTURING A DOCUMENT IN AN IMAGE SIGNAL

摘要

Devices, methods, and software are disclosed for an interactive user interface for capturing a frame of image data having a representation of a feature. In an illustrative embodiment, a device includes an imaging subsystem, one or more memory components, and one or more processors. The imaging subsystem is capable of providing image data representative of light incident on said imaging subsystem. The one or more memory components include at least a first memory component operatively capable of storing an input frame of the image data. The one or more processors may be enabled for performing various steps. One step may include receiving the image data from the first memory component. Another step may include attempting to identify linear features defining a candidate quadrilateral form in the image data. Another step may include providing user-perceptible hints for guiding a user to alter positioning of the device to enhance a capability for identifying the linear features defining a candidate quadrilateral form in the image data.

主权项

1. A device, comprising:
an imaging subsystem for generating image data; a monitor for displaying an image; and a processor enabled for:
receiving the image data;generating a reduced resolution frame based on an input frame of the image data, the reduced resolution frame comprising fewer pixels than the input frame;attempting to identify linear features defining a candidate quadrilateral form in the image data;displaying the reduced resolution frame on the monitor; andproviding a user-perceptible hint in the displayed reduced resolution frame for guiding a user to alter positioning of the device to improve the device's capability for identifying linear features defining a candidate quadrilateral form in the image data.
