1. An image processing apparatus for correcting a depth map corresponding to an image, the image processing apparatus comprising:
- a detection unit configured to detect an object included in the image;
a determination unit configured to determine whether the object detected by the detection unit is smaller than a predetermined size or larger than the predetermined size; and
a correction unit configured to correct distance information in a target area, the target area corresponding to an area of the object in the depth map, when the detected object is smaller than the predetermined size, and to not correct the distance information in the target area when the detected object is larger than the predetermined size,wherein the correction unit is further configured to acquire a confidence coefficient of the distance information, which indicates an estimated accuracy of the distance information, at each position of the depth map, and to correct the distance information in the target area using only the distance information of which the confidence coefficient is equal to or greater than a predetermined value,wherein the detection unit is further configured to determine a type of the detected object, andwherein the determination unit is further configured to change the predetermined size depending on the type of the detected object.

Abstract
An image processing apparatus for correcting, on the basis of an image and a depth map corresponding to the image, the depth map, includes: a detection unit that detects an object included in the image; a determination unit that determines whether a size of the object detected by the detection unit is a threshold or less; and a correction unit that corrects a distance in a target area which corresponds to an area of the object in the depth map, when the size of the detected object is the threshold or less.

19. A distance correction method executed by a computer for correcting a depth map corresponding to an image, the distance correction method comprising:
-
a detection step of detecting an object included in the image; a determination step of determining whether the object detected in the detection step is smaller than a predetermined size or larger than the predetermined size; and a correction step of correcting distance information in a target area in the depth map that corresponds to an area of the object, when the detected object is smaller than the predetermined size, and not correcting the distance information on the target area when the detected object is larger than the predetermined size, wherein the correction step comprises acquiring a confidence coefficient of the distance information, which indicates an estimated accuracy of the distance information, at each position of the depth map, and correcting the distance information in the target area using only the distance information of which the confidence coefficient is equal to or greater than a predetermined value, wherein the detection step comprises determining a type of the detected object, and wherein the determination step comprises changing the predetermined size depending on the type of the detected object. - View Dependent Claims (20, 26)
