I installed your OV5647 camera module for Jetson nano and driver for it.
I tested capturing image by running the example python codes from you git repository.
There was a big delay between showing image from example code and real movement.
Could you know how to reduce the delay?
My Jetson Nano is B01 and I checked kernel version and installed the driver accordingly, arducam-nvidia-l4t-kernel_4.9.140-32.4.3-20200716095813_arm64.deb.
I ran the example code like this
$ python3 arducam_displayer.py -d 0 --width 2592 --height 1944
