Abstract: Disclosed herein is an image recording device for recording a plurality of images on a single recording medium.

Abstract: An image recording device for recording one or more images on a single recording medium includes a frame memory having a plurality of frame memory areas, the number of which is at least one greater than the number of images arranged along a main scanning direction on a recording medium. Upon the completion of storage of image data in the a number of frame memory areas equal to the number of images arranged along the main scanning direction, a storage completion signal is produced. A recording unit is energized to automatically record the images on the recording medium in response to the storage completion signal, and new image data are stored in another frame memory area.

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.
