Abstract

Methods and apparatus to create and display stereoscopic and panoramic images are disclosed. Apparatus is provided to control the position of a lens in relation to a reference lens. Methods and apparatus are provided to generate multiple images that are combined into a stereoscopic or a panoramic image. An image may be a static image. It may also be a video image. A controller provides correct camera settings for different conditions. An image processor creates a stereoscopic or a panoramic image from the correct settings provided by the controller. A panoramic video wall system is also disclosed.

Claims

1. A camera, comprising:

a first and a second imaging unit, each imaging unit including a lens and a sensor;

the sensors of the first and second imaging unit being rotationally aligned in the camera with a misalignment angle that is determined during a calibration; and

a controller for applying the misalignment angle generated during the calibration to determine an active sensor area of the sensor of the first imaging unit and an active area of the sensor of the second imaging unit to generate a stereoscopic image.

2. The camera as claimed in claim 1, further comprising a display for displaying the stereoscopic image.

3. The camera as claimed in claim 2, wherein a pixel density of the sensor in the first imaging unit is greater than the pixel density of the display.

4. The camera as claimed in claim 1, wherein the stereoscopic image is a video image.

5. The camera as claimed in claim 1, wherein the misalignment angle is negligible and wherein image data associated with pixels on a horizontal line of the sensor of the first imaging unit is used to display an image on a display and image data associated with pixels on a horizontal line of the sensor of the second imaging unit is used to generate a horizontal line of pixels in the stereoscopic image.

6. The camera as claimed in claim 1, wherein the camera includes at least four imaging units, each including a lens and a sensor to create the stereoscopic image from two panoramic images.

7. The camera as claimed in claim 1, wherein the misalignment angle is about or smaller than 1 degree.

8. The camera as claimed in claim 1, wherein the misalignment angle is applied to determine a scan line angle for the sensor of the second imaging unit.

9. The camera as claimed in claim 1, wherein a scan line angle is determined based on a parameter value of the camera.

10. The camera as claimed in claim 1, wherein the misalignment error is applied to generate an address transformation to store image data of the active sensor area of the sensor of the second imaging unit in a rectangular addressing scheme.

11. The camera as claimed in claim 1, wherein the camera is comprised in a mobile computing device.

12. The camera as claimed in claim 1, wherein the camera is comprised in a mobile phone.

13. The camera as claimed in claim 1, wherein the lens of the first imaging unit is a zoom lens.

14. The camera as claimed in claim 1, wherein de-mosaicing takes place after correction of image data for rotational misalignment.

15. A camera system, comprising:

a first and a second imaging unit, each imaging unit including a lens and a sensor;

a first memory for storing data generated during a calibration that determines a transformation of addressing of image data generated by an active area of the sensor of the first imaging unit, the active area being determined during the calibration;

a second memory for storing image data generated by the active area of the sensor of the first imaging unit in accordance with the transformation of addressing of image data; and

a display for displaying a stereoscopic image created from data generated by the first and the second imaging unit.

16. The camera system as claimed in claim 15, wherein the transformation of addressing reflects a translation of an image.

17. The camera system as claimed in claim 15, wherein the transformation of addressing reflects a rotation of an image.

18. The camera system as claimed in claim 15, wherein the display is part of a television set.

19. The camera system as claimed in claim 15, wherein the display is part of a mobile entertainment device.

20. The camera system as claimed in claim 15, wherein the display is part of a mobile phone.
