发明名称 PICTURE PROCESSOR
摘要 PURPOSE:To realize a high-speed picture process by eliminating the noise component given the vertical digital process from the picture signal processed through the horizontal analog filter. CONSTITUTION:The analog signal of the horizontal line data given from picture input device 1 is applied to analog filter 6, and the noise signal is added to A/D converter 2 after cutting the frequency region of the noise signal. And the picture signal digitized via converter 2 is supplied to picture memory 3. After this, the noise component of the signal which was calculated through gradation distribution arithmetic circuit 7 and binary coding circuit 3 and underwent the vertical digital process is applied to binary noise eliminating circuit 9. And the vertical noise component is eliminated from the picture signal delivered from memory 3, thus realizing a high-speed picture process.
