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.

Video correction apparatus for camcorder

An apparatus and a method for recording/playing back a broadcasting signal wherein the broadcasting signal is separated into a video signal and an audio signal and then written into video and audio signal memories. The video and audio signals are read from the video and audio signal memories if a HISTORY mode key is ON. The operation is ended if a REVIEW key is OFF under the condition that the HISTORY mode key is off. If the REVIEW key is ON the write operation of the video signal into the video signal memory is stopped and it is discriminated whether a JOG key is ON or OFF. A video signalportion of a predetermined previous interval is read from the video signal memory if it is discriminated that the JOG key is OFF. If the JOG key is ON, a read timing signal is generated to read the video signal from the video signal memory according to an operation of the JOG key. The video signal is read from the video signal memory with an address being incremented, if it is discriminated that the JOG key is operated clockwise. If it is discriminated that the JOG key is operated counter-clockwise, the video signal is read from the video signal memory with the address being decremented.
