1. Changing the resolution as high as possible.
There is resolution switching in application software.
(However, the resolution is higher, display speed is lower)
2. Adjust video properties.
The format of the setting screen depending on the camera. But, the setting items are roughly the same.
At high, the image quality is reduced
When you check AE, If the outside light is dark, the
image quality decreases
If Gain increases, the noise component will be amplified. So, the image quality will decrease.
If you increase the brightness too much on software, the noise component will also increase.
Basically, it is recommended to set the external lighting to sufficient brightness, uncheck the AE (auto white balance) and reduce gain as much as possible.
