Title:
【発明の名称】動画像の追跡カーソル発生回路
Document Type and Number:
Japanese Patent JP2721459
Kind Code:
B2
Abstract:
A circuit for generating a moving image tracking cursor in a camera, including a pickup for converting optical information into an electrical signal, a video signal processor for separating the picked-up signal into luminance and color signal, a filter for filtering only a high-band component of the separated luminance signal, a converter for converting the filtered signal into a digital signal, a detector for receiving the digital signal by predetermined intervals of picture, dividing the receiving signal by a plurality of subscreens, and integrating it by the subscreens, a motion forecasting circuit for calculating the difference between a current signal output from the converter and a precedingly detected signal, a cursor generator for variably designating the location of cursor in the subscreen where the largest integration is detected proportionally to the predicted amount of movement of the object, and a signal converter for mixing the cursor signal and a composite video signal.
