DIGITAL IMAGE DATA FILTERING APPARATUS

摘要

a synchronization signal divider for receiving the composite image signal to thereby divide the horizontal/vertical synchronization signal; a window signal generator for generating a window signal for selecting the analog/digital converted part in the horizontal scanning line of the composite image signal with reference to the divided horizontal synchronization signal; storing the analog/digital converted data; and a filtering part for filtering the data memorized in the memory during the inactive time which excludes the active time of the window signals, and memorizing the filtered data in the memory.
