Abstract

Provided is a method for convergent type three-dimensional (3D) multi-viewpoint image acquisition. The method for acquiring a multi-viewpoint image in an image acquisition apparatus comprises the steps of: converting the image acquisition apparatus to a multi-viewpoint image photographing mode; if converted to the multi-viewpoint image photographing mode in the converting step, providing a plurality of geometric shapes to set a position of an object to be photographed within a screen and selecting a desired shape of the geometric shapes in response to an inputted shape selection signal; if the desired geometric shape is selected in the shape providing step, adjusting a position and a size of the selected geometric shape in response to a shape adjustment signal; and photographing a whole image having the object that places within the adjusted geometric shape in the adjusting step.

Claims

1. A method for acquiring a multi-viewpoint image in an image acquisition apparatus, the method comprising the steps of:

(a) converting the image acquisition apparatus to a multi-viewpoint image photographing mode;

(b) if converted to the multi-viewpoint image photographing mode in said step (a), providing a plurality of geometric shapes to set a position of an object to be photographed within a screen and selecting a desired shape of the geometric shapes in response to an inputted shape selection signal;

(c) if said desired geometric shape is selected in said step (b), adjusting a position and a size of the selected geometric shape in response to a shape adjustment signal; and

(d) photographing a whole image having the object that places within the adjusted geometric shape in said step (c).

2. The method as recited in claim 1, wherein said step (b) includes the steps of:

(b1) setting a focus for an object to be photographed;

(b2) if the focus of the object is set in said step (b1), providing a plurality of geometric shapes to set a position of the object to be photographed;

(b3) if the geometric shapes are provided in said step (b2), receiving selection information on a desired shape of the geometric shapes; and

(b4) arranging the geometric shape selected in said step (b3) to be placed at a center of the screen at an initial time.

3. The method as recited in claim 1, wherein said step (c) includes the steps of:

(c1) moving the selected geometric shape up, down, left and right in response to an up, down, left, and right movement signal;

(c2) adjusting a size of the selected geometric shape in response to a size adjustment signal; and

(c3) fixing the geometric shape whose position and size have been moved and adjusted in said steps (c1) and (c2).

4. The method as recited in claim 3, wherein the geometric shape is polygonal.
