摘要： A method and system for reducing ghost images in three-dimensional (3D) images are disclosed. The method comprises: calculating a brightness difference distribution between a left-eye image and a right-eye image; determining a space factor indicating a brightness change resulting from the brightness difference distribution on the left-eye image or the right-eye image, the space factor being determined according to two-dimensional (2D) positions where the brightness difference distribution occurs on the screen; and multiplying the brightness difference distribution by the space factor to obtain a compensated right ghost brightness and a compensated left ghost brightness, and respectively deducting the compensated right ghost brightness and the compensated left ghost brightness from the left-eye image and the right-eye image.

摘要： A method and a system of establishing depth of field data of a 3D image, applicable to a 3D image including a first and a second visual image. The system includes a storage module, an offset calculator, and a comparator. An offset vector matrix includes data fields in the same number as that of pixels of a first visual image. An offset calculator divides a reference frame by taking an ath first pixel of the first visual image as a center, and finds out a target frame having a minimum grayscale difference value with the reference frame from a second visual image, so as to calculate an offset vector value according to the minimum grayscale difference value. A comparator determines that the offset vector values of all the ath first pixels are recorded in the offset vector matrix, so as to convert the offset vector matrix into a depth map.
