Problem with small size of acquired frames

Hi

I built an environment for the ToF camera on my RaspberryPi3 without using the latest image provided by analogdevices.

I was able to confirm the operation of the ToF camera with "firstframe.py".

However, there was a problem that the size of the acquired frame became too small.

Latest image: frame details: width: 640 height: 960 type: depth_ir

In my case: frame details: width: 640 height: 480 type: depth_ir

How do I get the correct frame size?
