Abstract

An image capture unit and computer readable medium used in combination therewith is disclosed. In a preferred embodiment, the image capture unit includes an image capturing sensor, a visual display, an instance of the computer readable medium, and circuitry for integrating functionalities thereof. The computer readable medium causes sensor data received from the image capturing sensor to be processed. The sensor data includes a plurality of image tiles and position indicating data defining a respective relative position of each one of each image tiles. Each one of each image tiles includes data representing a discrete portion of visual content. The computer readable medium causes a feedback image be displayed on the visual display. Displaying the feedback image includes correlate the relative position of each one of each image tiles with at least one other image tile that has previously generated and displayed.

Claims

1. An image capture unit, comprising:

a position indicating system configured for generating position indicating data instances, wherein said position indicating data instances each includes data derived from translational movement of the image capture unit and from rotational movement of the image capture unit;

an imaging system configured for capturing an image of visual content; and

a data processing arrangement configured for deriving from at least one of said position indicating data instances a position of the image capture unit at a point in time when a captured image data instance was one of initiated, completed, and partially completed, wherein deriving the position of the image capture unit includes interpolating the position of the image capture unit from at least one of said position indicating data instances generated prior to a point in time when the captured image data instance was one of initiated, completed, and partially completed and at least one of said position indicating data instances generated after the point in time when the captured image data instance was one of initiated, completed, and partially completed.

2. The image capture unit of claim 1 wherein the interpolating of the position of the image capture unit includes determining a timeline offset dependent upon creation time information of said position indicating data instances and creation time information corresponding to the point in time when the captured image data instance was one of initiated, completed, and partially completed of the captured image data instance.

3. The image capture unit of claim 1 wherein the deriving of the position of the image capture unit includes using a plurality of said position indicating data instances to determine momentum of the image capture unit and using said momentum to determine the position of the image capture unit at a point in time when the captured image data instance was one of initiated, completed, and partially completed.

4. The image capture unit of claim 1 wherein the position indicating system includes at least one of:

a plurality of spaced apart sensors each configured for sensing translational velocity of the image capture unit;

a sensor configured for sensing rotational movement of the image capture unit about a rotational axis; and

a sensor configured for sensing translational acceleration of the image capture unit.

5. The image capture unit of claim 1 wherein the imaging system includes an array sensor configured for digitizing an area of said visual content.

6. The image capture unit of claim 5 wherein the position indicating system includes at least one of:

a plurality of spaced apart sensors each configured for sensing translational velocity of the image capture unit;

a sensor configured for sensing rotational movement of the image capture unit about a rotational axis; and

a sensor configured for sensing translational acceleration of the image capture unit.
