ArduCAM USB Camera Shield Application Note

In this case, the minimum exposure time is 260 master clock Time(see datasheet 0xD5 (213)

Fine Shutter Width Total Context A), and the maximum exposure time is one Frame time.

Basically it equals to total vertical resolution times 1 Row Time, but sometimes the vertical

blanking rows should be added to extend the exposure time if needed.

Given the master clock is 24MHz, the minimum exposure time is around 10.8us. And if

Windows Width register equals to 640, Horizontal Blanking register equals to 94, the row time

equals to 30.6us. If we want to set the exposure to 1ms, we can set the Coarse Shutter Width to 32.

Exposure = 0.1ms, RegAddr = 11, Value = 3
