When your camera isn't working in Windows 10 (or if you're using an external webcam), it might be a problem with your drivers. Go here for step-by-step instructions for checking your Windows drivers. Troubleshooting for Mac OS. If you are still having trouble with your camera, here is another solution to try: Check your app permissions. Microsoft Access is available for PC only. The most up-to-date version of Microsoft Access is always available with a Microsoft 365 subscription. Microsoft Access 2019 is the latest version of Access available as a one-time purchase. Previous versions include Access 2016, Access 2013, Access 2010, Access 2007, and Access 2003.

Ms access camera controller

The extended camera control interface, available starting in Windows 8, is used to control camera features during image capture. The driver can control these camera features:

  • the camera's flash
  • whether image pin and record pin are mutually exclusive
  • the region of interest in the image
  • video stabilization

Ms Access Camera Controller

The driver can also choose to perform a camera control operation asynchronously, meaning that all requests for an operation are rejected until the first request is completed. If the driver has successfully performed asynchronous camera control operations, it should trigger the KSEVENTSETID_CameraAsyncControl event. See KSPROPERTY_CAMERACONTROL_S_EX for more information.

UWP apps can access these properties to configure the camera:
