If you can ensure that the S/N ratio is very large, it can be used in the presence of ambient light.
Conversely, if the S/N ratio is small, ambient light may affect the misjudgment of the action.
To measure the ambient light, it is recommended to implement it according to the actual state of the customer.
若可以確保S/N比很大,在有環境光的情況下是可以使用的.
相反的,若S/N比很小,環境光可能會影響到動作誤判.
若要衡量環境光,建議根據客人實際的商品狀態去實施比較好
