Abstract
An image capturing device includes a first image capturing module, a second image capturing module and a focusing and image processing module. The first image capturing module includes a plurality of first phase focusing detectors, and the field of view of the second image capturing module is smaller than the field of view of the first image capturing module. The plurality of the first phase focusing detectors are used for generating a plurality of first sets of optical sensing signals. When one of the plurality of the first sets of optical sensing signals are selected by the focusing and image processing module to provide a first focal signal according to the selected first set of optical sensing signal, the first image capturing module and the second image capturing module adjust respective focal distances according to the first focal signal.
