Abstract

Imaging systems having multiple optical modules are provided to achieve higher zoom ratio and better displaying effect. The FOVs or focal length ranges of the multiple optical modules may be designed to achieve a zoom ratio higher than either of the multiple optical modules and a Picture-in-Picture function. The gravity center of the imaging system may not be significantly varied during the zooming in and zooming out of the multiple optical modules.

First claim

What is claimed is:

1. An imaging system comprising:
a first optical module comprising a first image sensor, said first optical module having a first field of view angular range;
a second optical module comprising a second image sensor, said second optical module having a second field of view angular range; and
an image processor configured to receive image data for a first image from the first optical module and image data for a second image from the second optical module and generate data to show the first image and the second image captured using the first optical module and the second optical module, respectively, within a display;
wherein:
the first field of view angular range is wider than the second field of view angular range,
the second image having a narrower field of view is displayed within the first image having a wider field of view, and
the second optical module and/or a carrier on which the first optical module and the second optical module are carried is configured to rotate to center the second image on a point selected by a user within the first image.

2. The imaging system of claim 1 , wherein a size of the second image displayed within the first image is selected by the user.

3. The imaging system of claim 1 , wherein a portion of the second image is displayed, and the displayed portion of the second image is selected by the user.

4. The imaging system of claim 1 , wherein the images are displayed such that the second image captured by the second optical module having the narrower field of view is displayed within a third image obtained from combining the second image and the first image captured by the first optical module having the wider field of view.

5. A method of displaying multiple images, said method comprising:
capturing, at a first optical module comprising a first image sensor, a first image, wherein said first optical module has a first field of view angular range;
capturing, at a second optical module comprising a second image sensor, a second image, wherein said second optical module has a second field of view angular range narrower than the first field of view angular range;
receiving image data for a first image from the first optical module and image data for a second image from the second optical module;
generating data to display the second image having a narrower field of view within the first image having a wider field of view; and
rotating the second optical module and/or a carrier on which the first optical module and the second optical module are carried to center the second image on a point selected by a user within the first image.
