For USB Cameras, if the device interface registry key location contains a DWORD registry entry EnableDependentStillPinCapture with a non-zero value, the dependent pin on such cameras will be used for photo capture.
EnableDependentStillPinCapture: REG_DWORD: 0x0 (Disabled) to 0x1 (Enabled) When this entry is set to Enabled (0x1), the capture pipeline uses Method 2 for Still Image Capture (assuming the firmware also advertises sup...
We need support on how to get a still image from the camera sensor by use of UVC still image trigger command. Currently, we are able to capture still image from video stream by use of the "IMFCaptureEngine" of windows...

to provide a standard USB video class driver. I think there is a bit of a terminology problem here. If the camera meets. the USB Video Class spec, then you don't NEED to write a driver. The. standard usbvideo.sys driv...
So, the current way of trigger still image capture is kind of "hybrid", which involves the GPIO interrupt and send status interrupt packet data as soon as trigger flag is set.
If the still pin is found, when pressing the “snapshot” button of the device, the OnFrameCaptureCompleted event should occur, returning the captured frame to a memory bitmap or an image file depending on the VideoGrab...
End user's view: it's means you can capture a still image with different size to the current preview size. e.g preview in 800x600, but you wanna still image in 1600x1200.
