ArduCAM USB Camera Shield Application Note 4 Tune the Sensor Registers 4.1 Identify the Sensor Version Sensor register address 0x00 is read only, and always return the chip vision 0x1313 when read it. Input the register address 0 in decimal to the RegAddr dialog box and click read button, the Value dialog box will show 4900 in decimal which is identical to 0x1313 in hex. 4.2 Adjust the Sensor Exposure The exposure is also called Pixel Integration Control.

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.
