Abstract
A camera phone includes a phone stage for generating voice signals, a first image sensor for generating a first sensor output, a first fixed focal length wide angle lens for forming a first image of the scene on the first image sensor, a second image sensor for generating a second sensor output, and a second fixed focal length telephoto lens pointing in the same direction as the first lens and forming a second image of the same scene on the second image sensor. A control element selects either the first sensor output from the first image sensor or the second sensor output from the second image sensor. A processing section produces the output image signals from the selected sensor output, and a cellular stage processes the image and voice signals for transmission over a cellular network.
