Abstract

Claims (44)

1. A method, comprising:

capturing via at least one image sensor of a monoscopic video camera, a two-dimensional video;

capturing via at least one depth sensor of said monoscopic video camera, corresponding depth information for said captured two-dimensional video; and

focusing on a portion among a plurality of portions of said two-dimensional video, wherein focusing comprises selecting said portion as a focal point for processing said two-dimensional video; and

scaling said two-dimensional video in response to a user-zoom, wherein scaling comprises resizing said portions of said two-dimensional video variably by:

scaling said focused portion at a focal depth plane using a first scale factor, the first factor generated based on said user-zoom: and

scaling another portion among said plurality of portions at another depth plane using a second scale factor, the second scale factor generated to be proportional to said first scale factor based on a relation between said focal depth plane and said another depth plane.

2. The method according to claim 1 , wherein, said variable scaling comprises adjusting and/or controlling one or more functions in an image sensor pipeline (ISP) utilized during image processing in said monoscopic video camera.

3. The method according to claim 1 , comprising:

determining a plurality of depth planes in said depth information; and

determining said plurality of portions of said two-dimensional video that are subjected to variable scaling based on said determined plurality of depth planes.

4. The method according to claim 1 , wherein said user-zoom comprises a user-input zoom factor.

5. The method according to claim 1 , comprising synchronizing said captured corresponding depth information to said captured two-dimensional video.

6. The method according to claim 1 , comprising:

composing three-dimensional video from said captured two-dimensional video based on said captured corresponding depth information; and

rendering said composed three-dimensional video via a display that is communicatively coupled to said monoscopic video camera.

7. A system, comprising:

one or more circuits for use in a monoscopic video camera that comprises at least one image sensor and at least one depth sensor, said one or more circuits being operable to:

capture via said at least one image sensor of the monoscopic video camera, a two-dimensional video;

capture via said at least one depth sensor of said monoscopic video camera, corresponding depth information for said captured two-dimensional video;

select a focal portion of said captured two-dimensional video;

identify a focal depth of said selected focal portion in said captured depth information; and

scale said two-dimensional video adaptively in response to a user-input zoom-factor and based on said depth information, said adaptive scaling comprising:

scaling said focal portion of said two-dimensional video with a first scale-factor, wherein said first scale-factor is calculated based on said zoom-factor; and

scaling a second portion of said two-dimensional video with a second scale-factor, wherein said second scale-factor is calculated based on said zoom-factor and proportion of depth of said second portion to said focal depth.

8. The system according to claim 7 , wherein said one or more circuits comprise an image sensor pipeline (ISP), and said one or more circuits are operable to perform said adaptive scaling by adjusting and/or controlling one or more functions in said image sensor pipeline (ISP) utilized during image processing in said monoscopic video camera.

9. The system according to claim 7 , wherein said one or more circuits are operable to determine a plurality of depth planes corresponding to said two-dimensional video based on said depth information.

10. The system according to claim 7 , wherein in response to said user input, said one or more circuits are operable to select a third portion of said two-dimensional video as said focal plane.

11. The system according to claim 7 , wherein said one or more circuits are operable to synchronize said captured corresponding depth information to said captured two-dimensional video.

12. The system according to claim 7 , wherein said one or more circuits are operable to compose three-dimensional video from said captured two-dimensional video based on said captured corresponding depth information.

13. The system according to claim 12 , wherein said one or more circuits are operable to render said composed three-dimensional video via a display that is communicatively coupled to said monoscopic video camera.

14. A device comprising:

an image sensor configured to capture a two-dimensional image;

a depth sensor configured to capture depth information corresponding to the captured two-dimensional image;

a processor further configured to operate the image sensor to select a portion of the two-dimensional image as a focal portion, wherein light from the focal portion is captured optimally;

the processor further operable to determine a focal depth of the focal portion from the captured depth information;

a control configured to receive a zoom command;

the processor configured to calculate a zoom-factor in response to the zoom command;

the processor further configured to calculate, in response to the zoom command, a first scale-factor to be applied to portions of the two-dimensional image at the focal depth, the scale-factor based on the zoom-factor and the focal depth;

the processor further configured to scale the portions in the two-dimensional image at the focal depth using the calculated first scale-factor in response to the zoom command;

the processor further configured to calculate a second scale-factor for a second portion in the two-dimensional image at a different depth than the focal depth, the second scale-factor based on the zoom-factor and a proportion of the focal depth and the depth of the second portion; and

the processor further configured to scale the second portion in the captured two-dimensional image using the second scale-factor.
