Title:
IMAGE SIGNAL OUTPUT DEVICE FOR TARGET EXTRACTION PROCESSING FOR IMAGE TRACKING SYSTEM
Document Type and Number:
Japanese Patent JPH02285874
Kind Code:
A
Abstract:
PURPOSE:To prevent waste time from being generated in scan conversion by performing the horizontal field scan of an optical system synchronizing with the vertical synchronizing signal of a television signal, and obtaining the perpendicular directional output of the optical system according to an address synchronized with the horizontal synchronizing signal of the television signal. CONSTITUTION:A scanner mirror 3 is scan-controlled so that the timing of the center of optical scan can correspond to that of the center of the perpendicular directional field in the television signal synchronizing with a scan synchronizing signal of NTSC system by a driving signal from a scan control circuit 14. The output of the detecting elements 8a of a detector 8 are amplified by video amplifiers 9-1-9-n, respectively, and are supplied to an analog multiplexer 10, and are converted to signals of (m) channels synchronizing with the horizontal synchronizing signal of NTSC system by the address from an address control circuit 13 at the multiplexer.
