PURPOSE:To reduce interference with a left image or between right and left image and to improve stereoscopic sense by processing one image information signal preceding by one field time and then adding the processed signal to the succeeding other image information signal. CONSTITUTION:An image information signal is inputted to an input terminal Vin, and after low pass processing the input signal, the signal is delayed by one field through a field delay 2, and the phase of the delayed signal is matched with that of an image information signal inputted to the next field. At the time of inputting a left side image information signal to the input terminal Vin in the case of interlacing signals at the rate of 4:2 in a subtracting circuit 5, a right side image information signal inputted before one field is level- converted by alpha through a level converter 3, subtracted from the left side image information signal to reduce crosstalk due to the right side image information signal. At the time of inputting the right side image information signal to the input terminal Vin, the left side image information inputted before one field is not subtracted. Thus, the stereoscopic sense can be improved. |
