Abstract
The present invention provides an imaging apparatus for converting a 24p imaging signal generated with a frame frequency of 24 Hz according to a progressive scanning system into asignal with a field frequency of 60 Hz by 2:3 pull-down processing according to an interlace scanning system which is a standard television system. The imaging apparatus prevents occurrence of a horizontal stripe and the like at the center of a screen and prevents degradation in picture quality. According to this inventive imaging apparatus, when the output timing of the 24p imaging signal from an imaging sectionis not equal to the phase of avertical synchronizing signal, the 24p imaging signal is inputted to a memory sectionafter being delayed by a delay sectionby a time during which thesignal is subjected to (½) field scanning, and the 24p imaging signal is written in the memory sectionin synchronization with thevertical synchronizing signal.
