雖然死神一般不會死，但如果死神死了，落在人間界的該本死亡筆記仍然有效。

In order to see the names and life spans of humans by using the eye power of the god of death，the owner must look at more than half of that person''s face。
When looking from top to bottom，he must look at least from the head to the nose。
If he looks at only the eyes and under，he will not be able to see the person''s name and life span。
Also，even though some parts of the face，for example the eyes，nose or mouth are hidden，if he can basically see the whole face，he will be able to see the person''s name and life span。

用死神眼看別人的姓名和壽命時，必須看到人臉的左右一半以上；上下的話，必須看到頭頂到鼻子部位，如果只是看到眼睛以下部位的話無效。另外，如果眼睛、鼻子、口等其中一個部位被遮掩起來的話，也可以看到。要遮掩外貌的百分之幾才會看不到姓名和壽命，這就有待死亡筆記的主人自己去驗證了。
If above conditions are met，names and life spans can be seen through photos and pictures，no matter how old they are。
But this is sometimes influenced by the vividness and size。

從照片和錄影上也可以看到該人的姓名和壽命，但根據大小和清晰度也有可能會看不到。不管多麼模擬的繪畫也是無效的。

Whenever an individual with ownership of more than two DEATH NOTES loses possession one of the DEATH NOTES； he will not be able to recognize that DEATH NOTE''S god of death''s appe
