Camera when shooting a moving object, if the object moves too fast, the camera's exposure time is too long, then the image will have a smear. This article is calculated to ensure maximum exposure time image does not smear.
If the object moving speed V = 100mm / s, the system resolution R = 1/100 (mm / pixel), the maximum exposure time T is calculated as:
Acceptable smear if allowed to be 5 pixels, the maximum exposure time T is calculated as:
