    Abstract: A method and a system for measuring a distance from a reference point to an object are provided. The method comprises the following steps. At least one image of an object is captured through a lens comprising a phase mask composed of a parallel plate and a wedge prism. At least two corresponding regions of interest (ROI) are obtained from the images. The regions of interest correspond to identical portions of the object. The relative coordinates between corresponding locations within the corresponding regions of interest is measured. The distance is calculated according to the relative coordinates.

    Abstract: A ranging apparatus including an image sensor, an imaging lens, and a processor is provided. The imaging lens is configured to image an object on the image sensor to produce an image signal having at least one image parameter, wherein the at least one image parameter changes with a change of an object distance of the object. The processor is configured to determine the change of the object distance according to a change of the at least one image parameter. A ranging method and an interactive display system are also provided.

    Abstract: An image refocusing method for use in an image processing apparatus is provided. The image processing apparatus has an image capturing unit and an image processing unit. The method has the following steps of: receiving lights of a scene via the image capturing unit to output a raw image having information of different views; rearranging the raw image from the image sensor to obtain multiple different view sub-images; performing a refocusing process to at least one specific view sub-image of the different view sub-images corresponding to a specific view to generate multiple refocused view images, wherein a first focusing position of the refocused view images is different from a second focusing position of the at least one specific view sub-image; and outputting the refocused view images to a stereoscopic display device.
