Abstract
PURPOSE: To secure a decision for the trouble of the transmission or reception picture memory based on the error emerging on the monitor by giving the opposite polarities to the picture signals which are memorized in the transmission and reception picture memories.
CONSTITUTION: The picture signal obtained through camera 1 is memorized in transmission picture memory 3 after conversion at the A/D converter. The signal reproduced from memory 3 is inverted for its polarity through 1st polarity inverter 8 and then transmitted by transmission circuit 4 to be memorized in reception picture memory 5. The signal reproduced from memory 5 is converted at D/A converter 6 after inversion received by 2nd polarity inverter 9 to be displayed on monitor 7. If the picture signals are changed into the opposite polarity to each other in advance when recorded in memories 3 and 5, the picture reproduced from the faulty picture memory is displayed in the opposite polarity when reproduced. As a result, whether the trouble belongs to the reception or transmission picture memory can be decided easily.
