METHOD & APPARATUS FOR DETECTING MOVEMENT VECTOR

摘要

A device and method for detecting a motion vector of a camcorder are disclosed. A main pick-up unit changes an image into an electrical signal, a vertical image pick-up segment calculates a correlation value between a present vertical line unit and a previous vertical line unit, and a horizontal segment calculates a correlation value between a present horizontal line unit and a previous horizontal line unit. The process is repeated through the limits of a searching area and for each pixel in the vertical and horizontal line pick-up units, and the correlation values are accumulated. Then the minimum vertical and horizontal correlation values are selected as the motion vector.
