According to one embodiment, a parallax image generating apparatus is for generating, using a first image, a parallax images with a parallax therebetween. The apparatus includes following units. The first estimation unit estimates distribution information items indicating distributions of first depths in the first image by using first methods. The distribution information items falls within a depth range to be reproduced. The first combination unit combines the distribution information items to generate first depth information. The second calculation unit calculates second depth information indicating relative unevenness of an object in the first image. The third combination unit combines the first depth information and the second depth information by using a method different from the first methods, to generate third depth information. The generation unit generates the parallax images based on the third depth information and the first image.

According to an embodiment, an image processing apparatus creates a depth map representing distribution of depths of pixels in an image. The apparatus includes an area detecting unit configured to detect an area of a vertical object included in an image; a base depth adding unit configured to add a base depth to the image, the base depth being a basic distribution of depths of pixels in the image; and, a depth map creating unit configured to acquire at least one depth of a vicinity of a ground contact position of the vertical object from the base depth added to the image, and create the depth map by setting the acquired depth onto the base depth as a depth of the area of the vertical object.

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.

An image processing apparatus according to an embodiment includes a displaying device, a receiver, a calculator, and a controller. The displaying device can display a stereoscopic image. The receiver receives a start signal used for starting setting a viewing zone in which the stereoscopic image can be viewed by a viewer. The calculator calculates, on the basis of position information of the viewer, viewing zone information representing a position of the viewing zone when the start signal is received. The controller controls the displaying device so as to set the viewing zone corresponding to the viewing zone information.
