An electronic camera for producing an output image of a scene from a
captured image signal includes a first imaging stage comprising a first
image sensor for generating a first sensor output and a first lens for
forming a first image of the scene on the first image sensor, and a
second imaging stage comprising a second image sensor for generating a
second sensor output and a second lens for forming a second image of the
scene on the second image sensor, where the lenses have different focal
lengths. A processing stage uses the sensor output from one of the
imaging stages as the captured image signal and uses the images from both
imaging stages to generate a range map identifying distances to the
different portions of the scene.
