Abstract

An image processing apparatus includes a distance information acquisition unit that acquires distance information, associated with an object image included in each of a first image and a second image, and corresponding to a distance in a depth direction of the object, a calculation unit that calculates a movement vector of the object image, at least in a horizontal direction and a vertical direction, based on position information of the object image, and a generation unit that generates stereoscopic print data of the acquired second image, based on the second image, the distance information, and the movement vector, by increasing a depth component of the position information of the object image included in the second image based on at least part of the movement vector. In addition, a storing unit stores the generated stereoscopic print data in one of a second memory and a recording medium.

Dependent claims

An image processing apparatus comprising:

(A) a photographing section that acquires a first image of an object and a second image of the object, the first image and the second image being acquired at different times, and each including an object image of the object and a background portion;
(B) at least one memory that stores instructions;
and
(C) at least one processor coupled to the at least one memory, and configured to execute the instructions to cause the image processing apparatus to function as:
(a) a distance information acquisition unit configured to acquire distance information associated with the object image included in each of the first image and the second image, the distance information corresponding to a distance in a depth direction of the object, and indicating a distance from the photographing section to the object;
(b) a movement vector calculation unit configured to calculate a movement vector of the object image in a horizontal direction, a vertical direction, and the depth direction, based on position information of the object image included in each of the first image and the second image;
(c) a thickness determination unit configured to determine a thickness of the object image, in the depth direction, included in each of the first image and the second image according to at least one of a horizontal component and a vertical component of the movement vector;
(d) a generation unit configured to generate stereoscopic print data based on (i) the second image, (ii) the distance information associated with the object image included in the second image and acquired by the distance information acquisition unit, (iii) the movement vector calculated by the movement vector calculation unit, and (iv) the determined thickness of the object image, by increasing a depth component of the position information of the object image included in the second image based on the at least one of the horizontal component and the vertical component of the movement vector, wherein the generation unit increases the thickness of the object image based on an increase of a scalar amount of the at least one of the horizontal component and the vertical component of the movement vector, without increasing a thickness of the background portion of the second image;
and
(e) a storing unit that stores the generated stereoscopic print data in one of a second memory and a recording medium.
