<p>The present invention is derived to control a natural convergence angle like being shown by left and right eyes of a person by controlling space of left and right cameras or space of photographed left and right images when an image is photographed in three dimensions. To control the convergence angle for forming a stably optimum there-dimensional effect, a depth map which expresses spatial distribution and a histogram which expresses properties such as the spatial distribution of the depth map are used. A general histogram of an image expresses how many brightness elements of the image are distributed. However, the histogram of the present invention expresses a spatial distance from an object or a background in a camera to photograph each of the elements rather than the brightness elements of the image. Therefore, entire spatial distribution can be identified using the depth map histogram which expresses the spatial distance, and a determination on where to set the convergence angle in the space can be made by determining an optimum convergence angle control location every image based on a reference input value inputted by a viewer according to changes in the image using an accumulation histogram.</p> |
