Abstract

A FIRST MOTION DETECTION CIRCUIT (102) DETECTS PRESENCE/ABSENCE OF MOTION IN AN IMAGE ON THE BASIS OF A COMPOSITE VIDEO SIGNAL (VD) AND AN OUTPUT SIGNAL OF A FRAME MEMORY (101). A THREEDIMENSIONAL Y/C SEPARATION CIRCUIT (103) SEPARATES A LUMINANCE SIGNAL (Y1) AND A CHROMINANCE SIGNAL (C1) FROM THE COMPOSITE VIDEO SIGNAL (VD) BY AN INTER-FRAME OPERATION OR AN INTRA-FRAME OPERATION ON THE BASIS OF A MOTION SIGNAL (MS1) OUTPUT FROM THE FIRST MOTION DETECTION CIRCUIT (102).A MOTION DETECTION CIRCUIT (107) DETECTS PRESENCE/ABSENCE OF MOTION IN THE IMAGE ON THE BASIS OF THE LUMINANCE SIGNAL (Y1) OUTPUT FROM THE THREE-DIMENSIONAL Y/C SEPARATION CIRCUIT (103). A SYNTHESIZING CIRCUIT (108) SYNTHESIZES MOTION SIGNALS (MS1, MS2) OUTPUT FROM THE FIRST MOTION DETECTION CIRCUIT (102) AND A SECOND MOTION DETECTION CIRCUIT (107). A THREE-DIMENSIONAL NOISE REDUCTION CIRCUIT (106) REDUCES NOISE OF THE LUMINANCE SIGNAL (Y1) OUTPUT FROM THE THREEDIMENSIONAL Y/C SEPARATION CIRCUIT (103) BY AN INTER-FRAME OPERATION OR AN INTRA-FRAME OPERATION ON THE BASIS OF AN OUTPUT SIGNAL OF THE SYNTHESIZING CIRCUIT (108).(FIG. 1)
