Abstract
A multi-focal camera apparatus and methods and mediums for generating a focus-free image and an autofocus image using the multi-focal camera apparatus are provided. The multi-focal camera apparatus includes a lens module which comprises a plurality of lenses that concentrate light incident thereupon, and an image-sensor module which comprises a plurality of sensing zones respectively corresponding to the lenses, and obtains a plurality of images by converting beams of light that transmit through the lenses into electrical signals using the sensing zones, wherein the lenses have the same optical properties and are different distances apart from the respective sensing zones.
