Hey Chanyong, I also faced a similar issue where if I took a snapshot with the webcam, the output is in uint8 RGB. This seems to be the default behavioras mentioned in the “snapshot” command documentation. You can refer to that here:
A possible solution is to try using the “Image Acquisition Explorer App” to check if MATLAB detects the camera’s ability to record in RAW16. To try this, first ensure that the “Image Acquisition Toolbox” is installed. You can refer to the following guide to install it:
Once it is installed, we can launch it using the command:
imageAcquisitionExplorer
If you do not see the desired camera, click on “Don’t see your device?” and install the necessary plugins to recognise your camera:
Once your camera is recognised, click on it to open the Image Acquisition App, and click on the “Configure Format” in the tool strip under the “Explorer” Tab:
If MATLAB recognises the camera, then RAW should show up as an option.
