即係相機內個ccd大小, 用來攝取影像.

thanks for reply, after visited the link, i still not understand....so conculsion is larger number more noise?

[gaiuswong]

因感光元件越細,佢裡面pixal點與點之間距離迫得密左,訊號就會互相干擾產生雜訊,所以理論上感光元件係越大越好,noise會低,例如DC計而家感光元件最大size係2/3吋,最細size係1/3.2吋.

oh, thank you...icic

so i could say, Casio S-100 (1/ 3.2)less noise than Casio Z-55 (1/2.5)less noise than Smasung V50(1/1.8)? right?

睇清楚係1/1.8=0.5555，1/2.5=0.4，1/3.2=0.3125。數字越大NOISE應較小。所以係1/1.8吋最好。

moky0609，你掉轉左............
分數入面，分母越大，整個數就會越細..........
所以1/3.2<1/2.5<1/1.8
