I have a USB-Based Camera with a Capture Button that takes a picture. However, this feature only works in a dedicated application. I think the button sends a signal that triggers an image capture function.
I checked in IrfanView and after selecting a TWAIN driver I can see the image from the webcam. I can press the acquire button and the picture saves on the disk. But pressing a button on the camera does nothing. It probably triggers some other event.
Do you have any idea how to capture this signal so that I can use this button in my application? |
