Abstract

Claims (24)

1. A mobile telephone, comprising:

a main body having a camera module mechanical interface;

a camera module having a main body mechanical interface complementary to said camera module mechanical interface, said complementary interfaces configured to allow said camera module to be moved from an exposed position to a retracted position, said camera module configured for rotation relative to said main body about at least one axis of rotation when said camera module is in said exposed position;

means for automatically rotating said camera module about said at least one axis of rotation through a user-definable first angle α in at least two steps, each step comprising an angular displacement of essentially a second angle β, wherein said second angle β is smaller than said angle of view γ of said camera module and said second angle β has a value of about 60% of said angle γ;

means for capturing a series of images with said camera module by capturing one image before rotating said camera module, capturing one image between each two consecutive steps of rotation and capturing one image after rotating said camera module;

a memory with a stored image-stitching software program for generating a panoramic image from said series of images by stitching together said series of images and a microprocessor by which said image-stitching software program can be executed; and

a memory for storing said panoramic image for display.

2. The mobile telephone as recited in claim 1 wherein a relative overlap between each image of said series of images is predefined and stored in said memory.

3. The mobile telephone as recited in claim 1 wherein said camera module is rotatable about at least 360°.

4. The mobile telephone as recited in claim 1 further comprising means for capturing a video sequence with said camera module during rotation of said camera module through said first angle α by capturing a plurality of images with a given frequency.

5. The mobile telephone as recited in claim 1 wherein said camera module is movable with respect to said main body between said retracted and said exposed position, in particular by means of a translatory movement.

6. The mobile telephone as recited in claim 1 further comprising user-releasable retaining means for holding said camera module in said retracted position and transporting means to automatically transport said camera module from said retracted position to said exposed position.

7. The mobile telephone as recited in claim 1 further comprising a display configured to display said panoramic image.

8. A mobile telephone, comprising:

a main body having a camera module mechanical interface;

a camera module having a main body mechanical interface complementary to said camera module mechanical interface, said complementary interfaces configured to allow said camera module to be moved from an exposed position to a retracted position, said camera module configured for rotation relative to said main body about at least one axis of rotation when said camera module is in said exposed position;

means for entering a first angle α for rotating said camera module about said at least one axis of rotation;

means for calculating a second angle β and a number of steps for rotating said camera module through said first angle α at said second angle β for each of said steps;

means for automatically rotating said camera module said number of steps about said at least one axis of rotation at said second angle β;

means for capturing a series of images with said camera module by capturing one image before rotating said camera module, capturing one image between each two consecutive steps of rotation and capturing one image after rotating said camera module, wherein said calculating is based on said first angle α and a relative overlap between each image of said series of images and wherein said first angle α is user-defined and entered employing said means for entering; and

a memory with a stored image-stitching software program for generating a panoramic image from said series of images by stitching together said series of images and a microprocessor by which said image-stitching software program can be executed.

9. The mobile telephone as recited in claim 8 further comprising a memory for storing said panoramic image for display.

10. The mobile telephone as recited in claim 8 wherein said means for calculating determines said second angle β from the equation β=γ(1−(said relative overlap)) where γ is an angle of view of said camera module.

11. The mobile telephone as recited in claim 8 wherein said relative overlap is user-defined and entered by a user employing said means for entering.
