ABSTRACT:
A video correction apparatus for a camcorder comprising a filter for removing a noise component from digital input video data, a mask processor for calculating a difference between a pixel value of the resultant video data from the filter and each of adjacent vertical and horizontal pixel values, taking absolute values of the calculated differences and adding the taken absolute values, to detect edge data for selection of an accurate characteristic point of the video data from the filter, a representative point determination circuit for selecting a maximum value in each motion vector detection region every field in response to the edge data from the mask processor and determining positions of the selected maximum values as representative point data, and a correlation calculator for inputting the edge data from the mask processor and the representative point data from the representative point determination circuit and calculating a correlation of the inputted data in a search region of a desired range.
