Burst mode camera in Android which can take multiple pictures

Question

I was trying to implement a burst mode camera in my app, which can take multiple pictures at the rate of 5-10(or more) snaps per second.

FYI I already saw the previ

Answer 1

I think a big part of the problem is the question: How does burst mode work in current phones? A couple of blogs point out that Google has confirmed that they will be adding a burst mode API.

I suspect current implementations work by setting exposure time to minimum and calling takePicture in a loop or using Camera.PreviewCallback

I played around with the latter for some computer vision projects and happened to look into writing a burst mode camera using this API. You could store the buffers you receive from Camera.PreviewCallback in memory and process them on a background thread.

If I remember correctly, the resolution was lower than the actual camera resolution, so this may not ideal.

Answer 2

Short of device-specific APIs offered by their manufacturers, the only way you can get a "burst mode" that has a shot of working across devices will be to use the preview frames as the images. takePicture() has no guarantees of when you will be able to call takePicture() again.
