更新了摄像头图像处理逻辑，包括在图像可用时的处理流程，确保即使在回调未准备好的情况下也能避免内存泄漏或异常行为。代码片段展示了如何获取并处理图像，以及在不同条件下释放图像资源。

    private class OnImageAvailableListener implements ImageReader.OnImageAvailableListener {
                @Override
                public void onImageAvailable(ImageReader reader) {
                    if( MyDebug.LOG )
                        Log.d(TAG, "new still image available");
                    if( picture_cb == null || !jpeg_todo ) {
                        // in theory this shouldn't happen - but if this happens, still free the image to avoid risk of memory leak,
                        // or strange behaviour where an old image appears when the user next takes a photo
                        Log.e(TAG, "no picture callback available");
                        Image image = reader.acquireNextImage();
                        image.close();
                        return;
                    }

                    List<byte []> single_burst_complete_images = null;
                    boolean call_takePhotoPartial = false;
                    boolean call_takePhotoCompleted = false;

                    Image image = reader.acquireNextImage();
            if( MyDebug.LOG )
                Log.d(TAG, "image timestamp: " + image.getTimestamp());
            ByteBuffer buffer = image.getPlanes()[0].getBuffer();
            byte [] bytes = new byte[buffer.remaining()];
