Abstract
The invention relates to a picture memory system for a video printer. Out of continuously incoming video signals, picture signals corresponding to one frame or one field are stored into each of a plurality of semiconductor memories, and the picture just passed can be searched and printed. Therefore, in unilaterally transferred video signals like in television, the desired pictures can be directly printed without incurring the inconvenience of using a video recorder. That is, the multiple steps of recording and reproducing are skipped, and therefore, the degradation of the picture quality can be prevented.
Claims6
A picture memory system capable of storing video signals from a video signal source to print selectively pictures out of the received video signals, said picture memory system comprising:
- input signal switching means for performing selection operations for user-adjustable time intervals so as to output the received video signals through one of a plurality of output terminals under the control of input control signals;
- memory means having a plurality of semiconductor memory devices, for storing output signals of said input signal switching means into relevant portions of said memory means in sequence;
- output signal switching means for selecting the relevant portions of said memory means in accordance with the control of output control signals to output the relevant video signals stored in the selected semiconductor memory device;
- a buffer for adjusting an output level of video signals output from said output signal switching means;
- and
- a video printer for printing output picture signals of said buffer in accordance with print control signals.
