Apparatus and method of temporal smoothing for intermediate image generation

The present invention relates to an adaptive temporal smoothing apparatus and method for an intermediate image combination. The present invention, past and current receiving an image disparity vector estimator for generating a past and present disparity vector (disparity vector) for each block of a predetermined size; And it includes past and present image and the past and temporal smoothing unit configured to generate a temporal smoothing the disparity vector by receiving a current disparity vectors, a temporal smoothing unit based on the average absolute difference between the previous and current image (mean absolute difference, MAD) to generate a different temporal smoothing the disparity vectors for each frame. According to the present invention, by applying a temporal smoothing adaptively according to the state of the image you can eliminate flicker of the intermediate image without degradation of image quality.
