Abstract
An unsatisfactory scene is disqualified as an image acquisition control for a camera. An image is acquired. One or more eye regions are determined. The eye regions are analyzed to determine whether they are blinking, and if so, then the scene is disqualified as a candidate for a processed, permanent image while the eye is completing the blinking.
Claims30
A method of selectively disqualifying a scene as a candidate for permanent capture, storage or processing, or combinations thereof, the method comprising:
- identifying a key feature within a scene in a preacquisition stage, in a video stream or within a collection of preview images, or combinations thereof;
- determining that an occluding object is currently occluding a significant portion of the key feature;
- rejecting the scene as a candidate for digital image capture due to the occluding;
- performing one or both of shape analysis and temporal analysis of movement of the occluding object relative to the key feature;
- and
- automatically acquiring a digital image after delaying for a period of time, wherein the delaying of said acquiring the new image corresponds to an estimated time for said occluding of said key feature to end based on said one or both of shape analysis and temporal analysis of movement.
One or more non-transitory computer readable media having code embedded therein for programming a processor to perform a method of selectively disqualifying a scene as a candidate for permanent capture, storage or processing, or combinations thereof, the method comprising:
- identifying a key feature within a scene in a preacquisition stage, in a video stream or within a collection of preview images, or combinations thereof;
- determining that an occluding object is currently occluding a significant portion of the key feature;
- rejecting the scene as a candidate for digital image capture due to the occluding;
- performing one or both of shape analysis and temporal analysis of movement of the occluding object relative to the key feature;
- and
- automatically acquiring a digital image after delaying for a period of time, wherein the delaying of said acquiring the digital image corresponds to an estimated time for said occluding of said key feature to end based on said one or both of shape analysis and temporal analysis of movement.
A digital image acquisition device, comprising:
- a lens and image sensor for acquiring digital images;
- a processor;
- and
- one or more computer readable media having code embedded therein for programming a processor to perform a method of selectively disqualifying a scene as a candidate for permanent capture, storage or processing, or combinations thereof, wherein the method comprises:
- identifying a key feature within a scene in a preacquisition stage, in a video stream or within a collection of preview images, or combinations thereof;
- determining that an occluding object is currently occluding a significant portion of the key feature;
- rejecting the scene as a candidate for digital image capture due to the occluding;
- performing one or both of shape analysis and temporal analysis of movement of the occluding object relative to the key feature;
- and
- automatically acquiring a digital image to replace the present image after delaying for a period of time, wherein the delaying of said acquiring the digital image corresponds to an estimated time for said occluding of said key feature to end based on said one or both of shape analysis and temporal analysis of movement.
