Shown below are the functions for the controller (IV-S30J).
- For details about the controller hardware (cameras, peripheral devices), see the "IV-S30J User's
Manual, Instruction and Hardware."
* The gray search time is true when the search area is 256 x 256 pixels, the model size is 64 x 64
pixels, and the contraction function is set to 3.
