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.
