    • An intermediate image producing method and a 3D display device therefor are provided to prevent flickering resulting in the change of a brightness value of a motion picture for a still object by using a previous transition vector estimated for pixels having no motion by a previous frame when producing an intermediate image from images input from at least two cameras. An intermediate image producing method includes the steps of adding pixel value differences between first and third frames per block and adding the same together(S901), and comparing the sum with a first threshold value(S903). A first center pixel of a block, of which a sum of the pixel value differences is higher than the first threshold value, is determined as a pixel having motion. A second center pixel of a block, of which a sum of the pixel value differences is lower than the first threshold value, is determined as a pixel having no motion. A current disparity vector corresponding to a motion vector between the first frame and a second frame is calculated and a previous disparity vector corresponding to a motion vector between the third frame and a fourth frame is calculated. An intermediate image is generated based on the current disparity vector for the pixel having motion, and based on the previous disparity vector for the pixels having no motion(S909,S911).
