Claim Text:
1. A stereoscopic image processing method comprising: transmitting a first control value for controlling a prism diopter of glasses and a second control value for controlling a focal length of glasses, at once; controlling the prism diopter of the glasses based on the transmitted first control value and the focal length of the glasses based on the transmitted second control value; and causing a prismatic effect on light passing through the glasses, wherein the controlling the prism diopter of the glasses comprises: calculating the prism diopter using a depth value and a distance between both eyes; and setting the prism diopter of the glasses to the calculated prism diopter, wherein the prism diopter is calculated using the following equation: prism diopter=D1/D2−D1/D3, where D1 is a distance between both eyes, D2 is a distance from an eye to a stereoscopic image, and D3 is a distance from an eye to a display, and wherein the controlling the focal length of the glasses comprises: calculating a focal length value using the depth value and a viewing distance; and setting the focal length of the glasses to the calculated focal length value, the focal length value being calculated using the following equation: 1/f3=1/f1−1/f2, where f1 is the viewing distance, f2 is a distance from an eye to a stereoscopic image, and f3 is the focal length value.
