converting device for converting 2-dimensional image to 3-dimensional image and method for controlling thereof

The control method of a three-dimensional image conversion device for converting a two-dimensional image to a three-dimensional image is disclosed. The control method according to the present invention includes the steps of displaying two-dimensional images to convert the three-dimensional image, the method comprising: receiving a user input indicative of the at least one object (object) that is included in the two-dimensional image, the received based on a user input to obtain the at least one object boundary in the included in the two-dimensional image by analyzing the two-dimensional images includes the step of separating each object, the at least one object to obtain the depth information of each object phase and aligning the separated object based on the acquired depth information, and generating a three-dimensional image.
