MULTI-LENS CAMERA AND CONTROL METHOD
First Claim
1. 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 said plural images according to said obtained displacement vector for producing said three-dimensional image.

Abstract
A dual lens camera for producing a three-dimensional image includes plural lens systems and a zoom mechanism. Initial correction data is constituted by a displacement vector of an amount and a direction of misalignment between plural images according to a superimposed state thereof for each of zoom positions of the lens systems. A vector detector, if a calibration mode is set, obtains a current displacement vector related to one first zoom position. A data processor outputs current correction data by adjusting the initial correction data according to the initial correction data and current displacement vector. If the current correction data is stored, a displacement vector is obtained from the current correction data according to a zoom position of the lens systems upon forming the plural images, to carry out image registration between the images according to the obtained displacement vector for producing the three-dimensional image.
