Camera Setting Issue

[pmd2245]

Hello Varvrar,

First of all thanks a lot for the job you have done.
I managed to run your app on my iPhone X and everything works well.
Nevertheless, I have some trouble regarding the camera settings. The camera is not focusing properly leading to blurred images.
Moreover, is there a way to tune the camera parameters (resolution, etc.) ?

Thanks,
Pm

Hello pm!

1. Yes, autofocus manually disabled. Reason of doing this is that in many cases we should know camera calibration parameters, but with autofocusing focal length changes.
   You can set fixed focal distance with changing parameter lensPosition to get sharp images at some certain distance [0,1] -> [near, infinite].
   Or you can comment/delete this line:
   https://github.com/Varvrar/ios_logger/blob/master/ios_logger/ViewController.mm#L81
   to enable autofocus back.

2. Yes you can change resolution by changing AVCaptureSessionPreset:
   https://github.com/Varvrar/ios_logger/blob/master/ios_logger/ViewController.mm#L56
   And you can change any camera parameter that Apple's AVFoundation allows to change. I used this framework to work with camera.

Hello
I am doing academic research using this repository. I made the above changes, but no difference.

I want to shoot with the zoom of the camera as it was originally.
But why do you feel the camera in this repository app is zoomed strangely?
Is it possible to change it?

I was able to solve it on my own.
UI device settings were wrong.

Thanks

@Shotaro-N I have the same problem (zoom of the camera). Can you tell me what did you modify?

@KuanWei-Tseng
In Xcode, it should match the device used.
Check the storyboad.
