Abstract
A picture signal processing apparatus and method is presented that determines whether there is an odd or even-number field signal in the picture signals received, by referring to flags that are turned on or off in accordance with the result of odd and even-number field detection. If the odd and even-number field flags are on, an image processing operation A is performed. If the odd-number field flag is on and the even-number field is off, an image processing operation B is performed. If the odd-number field flag is off and the even-number field is on, an image processing operation C is performed. In accordance with whether there is an odd or even-number field signal in the received picture signals, an appropriate image processing operation is selected from the different operations. That is, the received picture signals are processed in a mode suitable to the signals, so as to generate suitable image data. By automatically switching the picture signal conversion mode to an appropriate mode in accordance with the picture signals received, the apparatus and method eliminate the need for a user to perform a troublesome switching operation.
