Abstract:
A camera with a pair of lens/sensor combinations, the two lenses having different focal lengths, so that the image from one of the combinations has a field of view approximately two to three times greater than the image from the other combination. As a user of the camera requests a given amount of zoom, the zoomed image provided will come from the lens/sensor combination having the field of view that is next larger than the requested field of view. Thus, if the requested field of view is less than the smaller field of view combination, the zoomed image will be created from the image captured by that combination, using cropping and interpolation if necessary. Similarly, if the requested field of view is greater than the smaller field of view combination, the zoomed image will be created from the image captured by the other combination, using cropping and interpolation if necessary.
