Abstract

An image correction method include providing a left eye image and a right eye image; providing a left eye gazing position and a right eye gazing position; dewarping the left eye image according to the left eye gazing position and dewarping the right eye image according to the right eye gazing position to acquire a dewarped left eye image and a dewarped right eye image; correcting a brightness of the dewarped left eye image according to the left eye gazing position and correcting a brightness of the dewarped right eye image according to the right eye gazing position; and 3D rendering the dewarped left eye image and the dewarped right eye image to acquire a stereoscopic left eye image and a stereoscopic right eye image.

First claim

What is claimed is:

1 . An image correction method, comprising:
providing a left eye image and a right eye image; providing a left eye gazing position and a right eye gazing position; dewarping the left eye image according to the left eye gazing position and dewarping the right eye image according to the right eye gazing position to acquire a dewarped left eye image and a dewarped right eye image; correcting a brightness of the dewarped left eye image according to the left eye gazing position and correcting a brightness of the dewarped right eye image according to the right eye gazing position, such that a brightness imbalance between the dewarped left eye image and the dewarped right eye image is corrected; and 3D rendering the dewarped left eye image and the dewarped right eye image to acquire a stereoscopic left eye image and a stereoscopic right eye image.

2 . The image correction method according to claim 1 , wherein the dewarping the left eye image according to the left eye gazing position satisfies

wherein (u,v) is a coordinates of the left eye image, (u′,v′) is a coordinates of the dewarped left eye image, (x,y) is the coordinates of the left eye gazing position, and po(n−o) is a polynomial coefficient, m, n, and o are natural numbers, and i and j are non-negative integer indices representing mathematical powers of x and y, respectively.

3 . The image correction method according to claim 1 , further comprising:
providing an image; and segmenting the image into the left eye image and the right eye image.

4 . The image correction method according to claim 1 , wherein the providing the left eye gazing position and the right eye gazing position is implemented by using an eye tracking camera.

5 . The image correction method according to claim 1 , further comprising:
displaying the stereoscopic left eye imag
