Apparatus and method for generating motion blur in mobile terminal

摘要

An apparatus and a method for generating a motion blur in a mobile terminal are provided. It is determined whether motion halting occurs during video shooting. If the motion halting occurs, a motion vector of each block between first and second consecutive images where the motion halting has occurred is estimated. A motion blur is generated on the second image using the motion vector of each block, and the motion-blurred image is displayed on a display unit.

主权项

1. An apparatus for generating a motion blur in a mobile terminal, the apparatus comprising:
a motion blur generator for, when motion halting occurs during video shooting, estimating a motion vector of each block between first and second consecutive images where the motion halting has occurred, for generating a motion blur on the second image based on the motion vector of each block, and for displaying the motion-blurred image on a display unit, wherein the motion blur generator comprises: a motion estimator for dividing each of the first and second images into a plurality of blocks, and for estimating a motion vector of each block between blocks of the first image and blocks of the second image; a blur kernel estimator for estimating a motion blur kernel of each block based on the motion vector of each block; a blur adder for generating a third image by adding a motion blur on the first image based on the motion blur kernel of each block; and an image synthesizer for generating a fourth image by synthesizing the third image and the second image, and for displaying the fourth image on the display unit.
