So, I am building a camera app. Basically want the camera to display the image on the PI screen until I press a button.
I am using raspistill to accomplish this:
raspistill -w 1024 -h 768 -o image.jpg -t 9999 -tl 0
However what it is doing is jumping between preview mode and displaying the image it just took. I would be fine with it doing one or the other but having it quickly switch between modes while I am trying to preview the image is kind of annoying.
I do realize I could instead use preview without capturing images, and then when the button is pressed, stop the preview and then take an image, but it seems like the above is a nice optimization (takes less time).
Any ideas?
