Which library or API can

Answer 1

I would advise using the WIA (Windows Image Acquisition) API. For this you need the file "WIALib_TLB.pas" which will be created by Delphi automatically when following these steps:

1. Select "Project > Import Type Library" from the Menu
2. Select ""Microsoft Windows Image Acquisition 1.01 Type Library" from the list
3. Choose "Create Unit"
4. You will then get the unit "WIALib_TLB.pas"

Use the code from the following URL to see how you can enumerate the available devices and their properties and take a snapshot with the camera.

Sorry, the comments are in German, but I think the code is easy to understand
