Embodiment approach 2

[0147] The depth map processing unit 20 according to Embodiment 2 individually adjusts the shape of the depth map generated by the depth map generating unit 10 for each of a plurality of target regions specified by a plurality of externally set masks. At this time, processing is performed using a volume relief pattern described later so that the central portion within the target area has a different depth value from the peripheral portion. Specifically, processing is performed so that the central portion within the target area has a depth value with a larger protrusion amount than the peripheral portion. It is more preferable to perform processing such that the protrusion amount of the central portion changes gradually from the peripheral portion to the central portion within the target area, compared with the peripheral portion. It is also preferable to perform processing such that the target area becomes a curved depth shape. It will be specifically described below.

Embodiment approach 3

[0193] By the method of Embodiment 2, the shape of the depth of the object in the image can be estimated easily and with high accuracy. However, in an actual image, the positions and shapes of the vertices and roots of the relief pattern determined by the method of Embodiment 2 may be different. Does not necessarily coincide with the most protruding position of the object. Next, according to Embodiment 3 described below, it is possible to estimate the depth shape of an object in an image with higher accuracy. Hereinafter, specific examples will be given and described for cases where it is more effective to use Embodiment 3. FIG.

Abstract

The present invention provides a depth estimation device, a depth estimation method, a depth estimation program, an image processing device, an image processing method and an image processing program. The outline determination unit determines the outline of the object in the object image. The distance specifying unit obtains the shortest distance between the target pixel and the contour in the target area. The depth value determination unit determines the depth value of the target pixel based on the distance. The distance specifying unit can obtain the shortest distance to the contour by taking the position of the target pixel as the center, and searching for the tangent point with the contour spirally from the center.

Description

technical field [0001] The present invention relates to a depth estimation device, a depth estimation method, a depth estimation program, an image processing device, an image processing method, and an image processing program for estimating the depth of an object in an image. Background technique [0002] In recent years, 3D image contents (contents) such as 3D movies and 3D TV programs are gradually becoming popular. In order for the viewer to perform stereoscopic viewing, right-eye images and left-eye images with parallax are required. When displaying 3D video, the right-eye image and the left-eye image are time-divisionally displayed, and the right-eye image and the left-eye image are separated by image separation glasses such as shutter glasses or polarizing glasses. Accordingly, the viewer can view the right-eye image only with the right eye, and view the left-eye image only with the left eye, thereby performing stereoscopic viewing. Also, if the right-eye image and t...
