An adjustment method of a convergence point for zoom-in on a dual lens stereoscopic camera

Recently, even non-professional photographers are using a dual lens stereoscopic camera which allows for convenient stereoscopic photography. The necessity for the research comes up, since the dual lens stereoscopic camera can cause visual discomfort during zoom-in due to the fixed convergence point. We propose a method based on which a convergence point can be adjusted to prevent visual discomfort during zoom-in for a dual lens stereoscopic camera. First, the relational model is classified into nine kinds and defined, depending on locations of focus, object, and convergence point. And then, the method to minimize visual discomfort is suggested by adjusting convergence point on the given model.
