Interactive user interface for capturing a document in an image signal
First Claim
1. A device, comprising:
- an imaging subsystem for generating digital image data;
a first memory component for storing an input frame of the digital image data;
a second memory component;
a monitor for displaying an image; and
a processor enabled for;
receiving the input frame of the digital image data from the first memory component;
generating a reduced resolution frame based on the received input frame of the digital image data, the reduced resolution frame comprising fewer pixels than the input frame;
displaying the reduced resolution frame on the monitor; and
then, in response to a command associated with the display of the reduced resolution frame on the monitor, saving the input frame to the second memory component.

Abstract
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.

7. A device, comprising:
-
an imaging subsystem for generating digital image data; a monitor for displaying an image; and a processor enabled for; receiving the digital image data; generating a reduced resolution frame based on an input frame of the digital image data, the reduced resolution frame comprising fewer pixels than the input frame; displaying the reduced resolution frame on the monitor; repeating the steps of receiving the digital image data, generating the reduced resolution frame, and displaying the reduced resolution frame to display a preview stream on the monitor, so that the preview stream comprises a plurality of reduced resolution frames displayed on the monitor in series, so that a first reduced resolution frame of the plurality of reduced resolution frames is displayed on the monitor followed by a second reduced resolution frame of the plurality of reduced resolution frames being displayed on the monitor; and in response to a command associated with the second reduced resolution frame being displayed on the monitor, saving a higher resolution frame corresponding to the second reduced resolution frame. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A device, comprising:
-
an imaging subsystem for generating digital image data; a monitor for displaying an image; and a processor enabled for; receiving, in real time, the digital image data; generating, in real time, a reduced resolution frame based on an input frame of the digital image data, the reduced resolution frame comprising fewer pixels than the input frame; displaying, in real time, the reduced resolution frame on the monitor; in response to a command, saving a higher resolution frame corresponding to the displayed reduced resolution frame; and in response to the command, displaying the higher resolution frame and the reduced resolution frame on the monitor. - View Dependent Claims (15, 17, 18, 19, 20)
