Fast way to capture single images from Camera [closed]

Closed 9 years ago.

Since I could not find any useful documentation that shows how to get just single frames/images from camera I'm asking it here, may be somebody has a hint where to start.

I want to use single images from camera in a fast way. Means I want to retrieve a single image, then do some internal processing on it (which may need some time) and retrieve the next image as soon as this processing has beend one.

I found some examples/documents that describe retrieving of single images via an Intent that makes use of external applications - but that seems to be too slow for me. Beside of that some of these examples stored the image on disk where one would have to load it - which is way to slow too.

So how can I capture a single frame out of my own application so that the image is returned in memory using a format that can be used for further image processing? Examples I found here at stackoverflow.com and on other pages make use of camera App - that's not what I want.

You should use the Camera class and call takePicture. Then you simply register a handler for PictureCallback.onPictureTaken.
