PURPOSE:To obtain a mobile screen with the reduced capacity of a memory, by obtaining a joined screens over at least two screens of the static picture information. CONSTITUTION:The output of a TV camera is supplied to a picture memory 5 via an A/D converter 20 and then fetched into the memory 5 as the static picture information with such time interval by which the screen overlaps the preceding screen. The read output of the memory 5 is recorded to a disk recorder/ reproducer 7, and at the same time the joint information of each screen is also recorded the disk 7. The reproducing output of the disk 7 is written into 16 frame picture memories M1-M16 for instance. The joint information (f) contained in the reproducing output is applied to an address generator 21. The generator 21 generates an address to read out the picture memories successively and at the same time generates a switch signal (g) at a joint to give the control to a changeover switch 22. The output of the switch 22 is converted into an analong video signal through a D/A converter 23. |
