Portrait image synthesis from multiple images captured on a handheld device

摘要

A hand-held digital image capture device (digital camera) has a user-selectable mode in which upon engaging the mode the device detects a face in the field of view of the device and generates a face delimiter on a camera display screen, the delimiter surrounding the initial position of the image of a the face on the screen. The device is arranged to indicate thereafter to the user if the device departs from the movement along a predetermined concave path P with the optical axis of the device pointing towards the face, such indication being made by movement of the image of the face relative to the delimiter. The camera captures and stores a plurality of images at successive positions along the concave path.

主权项

1. A hand-held digital image capture device, comprising:
a lens and an image sensor for capturing digital images; a display unit configured to display the digital images on a display screen; a digital processor operatively coupled to the image sensor and the display unit, and configured to:
upon detecting a particular object in a field of view in front of a user of the device:
upon receiving a user input, automatically capture a plurality of digital images of the particular object only upon detecting that the hand-held image capture device is repositioned along a concave path with respect to an optical axis of the hand-held digital image capture device pointing toward the particular object;wherein the concave path has an approximately constant radius centered at the particular object; andstore the plurality of digital images in a storage device.
