PURPOSE:To display a stereoscopical submarine image, by storing submarine sectional images obtained repeatedly at intervals of a certain time and shifting images successively to display them on the same sceen in different colors. CONSTITUTION:Picture data stored in a sumbarine sectional image storing circuit 6 are read out successively, and each submarine sectional image is stored in a stereoscopical image storing circuit 8 while setting a required level to it in a display color setting circuit 7. and picture data are read out successively, and respective set levels are converted to color signals different from one another in a coloring circuit 9 and are displayed on a CRT display 10. A shift circuit 12 makes levels of respective picture data different from one another together with the display color setting circuit 7 to store them in the stereoscopical image storing circuit 8 for the purpose of distinguishing picture data from one another. This shift operation of picture data is repeated, and picture data overflowed from the stereoscipical image storing circuit 8 is erased successively by an overflow image erasing circuit 13. This operation is repeated to display a submarine sectional image stereoscopically. |
