いう方法がある。
One method of writing an image signal in a storage tube and reading it out is to perform a write scan during the retrace period of the read scan.

これをリアルタイム動作と呼ぶ。This is called real-time operation.

所で従来このリアルタイム動作を行なわせる方法として
1フレームの画像信号が受信される毎にあらかじめ蓄積

However, as a conventional method for performing this real-time operation, each time one frame of image signal is received, the image previously written in the storage tube is erased and the newly received image signal is stored, and the erasing and writing are performed back and forth. Accumulated image from the previous area by the area required for writing (one scanning line)
There is a known method of erasing the image signal and writing a new image signal at the erased position.

後者の方法は前者の方法に比べ前後の蓄積画像が並んで

Compared to the former method, the latter method has the advantage that the stored images before and after are displayed side by side, making it possible to compare before and after in monitoring, etc. However, since the erase and write positions are close to each other, it is difficult to erase and write. If the positioning signal goes out of order even slightly,
Erasing errors may occur, such as not erasing the previous accumulated screen or erasing a new write signal.
