IMX519 16MP Autofocus resolution cropping

  1. Where did you get the camera module(s)?

  2. Model number of the product(s)?
    IMX519 16MP Autofocus

  3. What hardware/platform were you working on?
    Raspberry P 4

  4. Instructions you have followed. (link/manual/etc.)
    Raspberry Pi libcamera Guide - Arducam

  5. Problems you were having?
    What resolutions retain the original view angle / FoV?
    Some resolutions appear to crop the center of the image (eg: 640x480). I would like a lower resolution, higher FPS version of the whole image. Is this possible?

  6. The dmesg log from your hardware?
    dmesg | grep arducam > there is no output
    v4l2-ctl --list-formats-ext > 45 entries, along the lines of

[45]: 'Y14 ' (14-bit Greyscale)
		Size: Stepwise 16x16 - 16376x16376 with step 1/1

  1. Troubleshooting attempts you’ve made?

Tried testing various resolutions. Some are cropped, some are not.

  1. What help do you need?

I would like to know what resolutions are not cropped, or how I can stop it from cropping. I am using:
libcamera-still -o libcam640x480.jpg --width 640 --height 480
libcamera-still -o libcam4656x3496.jpg --width 4656 --height 3496
etc, etc

Chech this:

2328x1748 is 2x2 binned at maximum resolution, it doesn’t have any viewing angle penalty.

Thank you @wong, that’s very helpful

Are there any future plans to provide scaled images? So when specifying width and heights of say 640x480 it sends the full res scaled?

I would very much like that, if it’s possible.

@wong is this possible or planed for?

This is Bin from Arducam. Our engineer Wong is on vacation. Recently we don’t have planed fir this configuration.
