If you try using the SaveStillBitmap method, and it also
produced a delay with your device, you could consider using an indirect approach to do it.


 


If you would like me to suggest a different approach, please
explain how the process is going to be done. For example, will the user be
previewing live video and at a certain point click a button to capture the current frame? Please provide as many details as possible.

SaveStillBitmap is almost the same
Can you please suggest a different approach?
User previewing live video and at any time he want to take still images when he press a key
And maybe the difference between images is less than 3 second

Thank you

You could use our Callback filter, which can give you access
to the pixel data of every video frame that passes through it. You can then
respond to the user's click by taking the next video frame from this Callback
and pass it to any function that creates a bitmap from the pixel data, then
save the bitmap to disk. Since this works in real time, the delay will be almost zero between the user's click and the actual frame being saved.
