Abstract
An input telecine image is held by a field memory, and correlation values of respective images in a first field and a second field are calculated by correlation value calculation circuits. The correlation values are compared with a predetermined threshold value, and when the correlation value is smaller than the threshold value, a duplicated field is determined. Moreover, the correlation values of the first and second fields are compared in the correlation value comparison circuits, and the duplicated fields are determined. These information are held by a phase holding circuit. A phase pattern of a successive images converted by a 3:2 pulldown method is searched by a phase synchronization circuit on the basis of the information of phase obtained by the phase holding circuit. A control unit inversely converts automatically the telecine image including successive images converted by a method different from the 3:2 pulldown method to a film image.
