4.4.1 How to Configure Camera Output

The Piranha H S cam eras offer great flexibility w hen configu ring you r cam era ou tpu t.
Using the
nu m ber of ou tpu t taps, and bit d epth. Using the
cam era's ou tpu t rate. These tw o com m and s w ork together to d eterm ine you r final cam era
ou tpu t configu ration.
You can fu rther configu re you r read ou t u sing the
pixel read ou t d irection.
The follow ing tables su m m arize the possible cam era configu rations for each of the H S-xx
cam era m od els. Refer to the figu re below for a d escription on how to select you r cam e ra
