保存PreviewImage有一个绿色色调 - Android

Question

保存图像后有绿色调。表面支架上的预览图像看起来很正常。我该怎么做才能删除它？

mCamera.setPreviewCallback(new Camera.PreviewCallback() {
    @Override
    public void onPreviewFrame(byte[] data, Camera camera) {

        try {

            if (saveImg) {
                int width = parameters.getPreviewSize().width;
                int height = parameters.getPreviewSize().height;

                YuvImage yuv = new YuvImage(data, parameters.getPreviewFormat(), width, height, null);

                ByteArrayOutputStream out = new ByteArrayOutputStream();
                yuv.compressToJpeg(new Rect(0, 0, width, height), 100, out);

                byte[] bytes = out.toByteArray();
                final Bitmap bitmap = BitmapFactory.decodeByteArray(bytes, 0, bytes.length);

                File file = new File(Environment.getExternalStorageDirectory() + "/newimage.png");
                ByteArrayOutputStream os = new ByteArrayOutputStream();
                bitmap.compress(Bitmap.CompressFormat.PNG, 100, os);
                byte[] blobArray = os.toByteArray();

                FileOutputStream fos = new FileOutputStream(file);
                fos.write(blobArray);
                fos.close();

我最终为白平衡设置此值以删除绿色：

parameters.set("whitebalance", WHITE_BALANCE_FLUORESCENT);
mCamera.setParameters(parameters);
