摘要： According to one embodiment, a parallax image generating apparatus includes a deriving unit, a generating unit, a first calculating unit, a setting unit, a searching unit, and an interpolating unit. The deriving unit derives a parallax vector corresponding to a first pixel from the input image and depth information associated with the first pixel. The generating unit generates an intermediate image. The first calculating unit calculates first weights for respective pixels of a parallax image. The setting unit sets one or more candidate blocks near a shade-forming-area pixel of the intermediate image, and sets a reference block among one or more candidate blocks. The searching unit searches a target block similar to the reference block in the input image and/or the intermediate image. The interpolating unit interpolates a pixel value of the shade-forming-area pixel.

摘要： According to one embodiment, an image processing method includes calculating an activity value for a first block, the activity value indicating a higher degree of activity as pixel values vary in a greater degree in the first block, and calculating a first evaluation value that indicates higher evaluation as a difference between a pixel value of the first block and a pixel value of a second block is smaller. The method further includes calculating a second evaluation value that indicates higher evaluation as correlation between a relative spatial relationship of the pixel value of the first block and that of the pixel value of the second block is higher, and calculating a third evaluation value by weighting the first evaluation value and the second evaluation value to search for the second block that corresponds to the first block, a weight of the first evaluation value is larger as the activity value is larger.
