Abstract
A video image storage device comprises a signal input means capable of analog-to-digital conversion of input video signals including various types of scanning lines such as different numbers of scanning lines, a frame memory means capable of memorizing image signals and signal output means. The video image storage device further comprises an input signal generating means, an output signal generating means and a frame memory control means. The input signal generating means comprises a N multiplying circuit capable of N multiplying horizontal synchronizing pulses. The number of N in a dividing circuit can be arbitarily determined by the relation between effective image period and blanking period, and thus the video image storage device can store input video signals having different scanning line numbers which depend upon the types of diagnostic modalities.
