3D image processing apparatus and method
First Claim
1. An image processing apparatus comprising:
- an image dividing unit which receives a three-dimensional (3D) image and divides the 3D image into a left-eye image and a right-eye image;
a histogram generation unit which breaks down the left-eye image and the right-eye image into blocks, estimates disparities between all of the blocks of the left-eye image and the right-eye image, measures a frequency with which the estimated disparities occur, and generates a histogram representing all of the estimated disparities and the measured frequency;
a horizontal movement value determination unit which determines a horizontal movement value for the left-eye image and the right-eye image using the generated histogram; and
a horizontal movement unit which horizontally moves at least one of the left-eye image and the right-eye image based on the determined horizontal movement value,wherein the horizontal movement value determination unit calculates a threshold value which renders a predetermined ratio of the disparities in the histogram to be positive and determines the horizontal movement value using the calculated threshold value.

Abstract
Provided are an image processing apparatus and method which can adjust the disparity of an input three-dimensional (3D) image and stably display the 3D image. The image processing apparatus includes: an image dividing unit receiving a 3D image and dividing the 3D image into a left-eye image and a right-eye image; a histogram generation unit estimating disparities between the left-eye image and the right-eye image, measuring a frequency with which the estimated disparities occur, and generating a histogram of the disparities and the frequency; a horizontal movement value determination unit determining a horizontal movement value for the left-eye image and the right-eye image using the generated histogram; and a horizontal movement unit moving the left-eye image and the right-eye image horizontally based on the determined horizontal movement value. The image processing apparatus can control convergence of an image to enhance 3D effects and reduce eye fatigue.
