Patent ID: 8854432

Claim:
A multi-lens camera for producing a three-dimensional image from plural images with parallax, comprising: plural lens systems for receiving entry of object light to form said plural images; a zoom mechanism for changing a magnification of each of said lens systems within a zooming range; a first correction data memory for storing initial correction data constituted by a displacement vector of an amount and a direction of misalignment between said plural images according to a superimposed state thereof for each of zoom positions of said lens systems; a mode designation device for setting a calibration mode for adjusting said initial correction data; a vector detector for, if said calibration mode is set, obtaining a current displacement vector between said plural images in relation to one first zoom position; a data processor for outputting current correction data by adjusting said initial correction data according to said initial correction data and said current displacement vector; a second correction data memory for storing said current correction data; an image registration processor for, if said current correction data is absent in said second correction data memory, obtaining a displacement vector from said initial correction data according to a zoom position of said lens systems upon forming said plural images, and if said current correction data is stored in said second correction data memory, obtaining a displacement vector from said current correction data according to a zoom position of said lens systems upon forming said plural images, to carry out image registration between the plural images according to said obtained displacement vectors for producing said three-dimensional image.
