Abstract
A method for processing an image includes capturing a current frame and a previous frame and performing uni-directional motion estimation on the same for obtaining an initial motion vector; performing motion compensated interpolation with respect to the current and previous frames, and the motion vector for acquiring an interpolated frame; calculating and obtaining second motion vectors corresponding to target blocks in the current frame symmetrically using the interpolated block as a center; calculating and obtaining third motion vectors corresponding to the second motion vectors in the previous frame; obtaining distance values using a motion trajectory calibration process with respect to the second and third motion vectors; and obtaining the minimum distance value from the distance values and performing a bi-directional motion compensation process with respect to the motion trajectory corresponding to the minimum distance value obtained from the distance values.
