    CPC classification number: H04N13/327

    Abstract: An apparatus and method for measuring 3-dimensional (3D) interocular crosstalk is disclosed. A light sensor detects luminance of a stereoscopic image displayed in a display and outputs a luminance value indicating the detected luminance. A controller calculates 3D interocular crosstalk based on a gray difference and a residual luminance ratio.
