Method of correcting distortion of image overlap area, recording medium, and execution apparatus

Abstract

Disclosed herein is a method of correcting the distortion of an image overlap area. The method includes identifying an overlap area between images projected by a plurality of projectors, obtaining information about the brightness of an image projected on the overlap area, and controlling the brightness of the image projected on the overlap area. Controlling the brightness of the image includes incorporating a transparency variable a into the image, and the transparency variable of an image projected by a specific projector is reduced toward remaining boundaries of the overlap area at a boundary of a non-overlap area and the overlap area.

Description

technical field [0001] The present invention relates to an image processing method, and more particularly, to a method of correcting distortion of an image by correcting overlapping regions included in images projected by a plurality of projectors so as to provide an image having a sense of unity as a whole. Background technique [0002] In the related art, in order to play images such as movies and advertisements in a movie theater, two-dimensional (2D) images are projected on a single screen provided in front of the movie theater. In such a system, viewers inevitably perceive only 2D images. [0003] Recently, a 3D image-related technology capable of providing a stereoscopic image to viewers has been developed. This 3D image technology is based on the principle that when different images enter a person's left and right eyes and merge in the brain, the person can feel a three-dimensional effect even in a 2D image. In this 3D image technology, images are captured using two...

Problems solved by technology

[0004] However, this 3D technology can provide users with stereoscopic images, but there is a problem that because users only watch the images played on a single screen, the degree of immersion in the images themselves is low.

Moreover, there is a problem in that the direction of the three-dimensional effect experienced by the viewer is limited to the direction of the single screen setting

The rationale for this is that in a multi-projection system the image correction process is very complex and there is a high probability that errors may occur due to multiple images projected on multiple projection surfaces rather than a single projection surface needing to be combined and corrected , and the method of correcting multiple images needs to be changed according to the structure of the cinema
