Android 3.0 Honeycomb added Device API support. Google I/O 2011 presentation shows an example on slide 30: <input type=”file” accept=”image/*;capture=camera”> It also points to a test site that not surprisingly does not do much on my Froyo phone. Anybody with a tablet tried it and can tell us what it does and does not do? … Read more
The picture is always taken in the orientation the camera is built into the device. To get your image rotated correctly you’ll have to read the orientation information that is stored into the picture (EXIF meta data). There it is stored how the device was oriented, when the image was taken. Here is some code … Read more
please see below answer. Custom_CameraActivity.java public class Custom_CameraActivity extends Activity { private Camera mCamera; private CameraPreview mCameraPreview; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); mCamera = getCameraInstance(); mCameraPreview = new CameraPreview(this, mCamera); FrameLayout preview = (FrameLayout) findViewById(R.id.camera_preview); preview.addView(mCameraPreview); Button captureButton = (Button) findViewById(R.id.button_capture); captureButton.setOnClickListener(new View.OnClickListener() … Read more
I also faced same issue in Samsung devices, later I implemented ExifInterface and solved successfully. In any mode images will be shot it will always store in portrait mode only, and while fetching too returning in portrait mode. below of code I used to achieve my goal, I implemented within back camera, not sure about … Read more
My problem was much simpler 🙂 All I had to do is cancel previously called autofocus. Basically the correct order of actions is this: protected void focusOnTouch(MotionEvent event) { if (camera != null) { camera.cancelAutoFocus(); Rect focusRect = calculateTapArea(event.getX(), event.getY(), 1f); Rect meteringRect = calculateTapArea(event.getX(), event.getY(), 1.5f); Parameters parameters = camera.getParameters(); parameters.setFocusMode(Parameters.FOCUS_MODE_AUTO); parameters.setFocusAreas(Lists.newArrayList(new Camera.Area(focusRect, 1000))); … Read more
Although the documentation suggests that you can set which format the image data should arrive from the camera in, in practice you often have a choice of one: NV21, a YUV format. For lots of information on this format see http://www.fourcc.org/yuv.php#NV21 and for information on the theory behind converting it to RGB see http://www.fourcc.org/fccyvrgb.php. There … Read more
MSM_CAM_IOCTL_GET_PICTURE is a kernel call which runs the function static int msm_get_pic(struct msm_sync *sync, void __user *arg) I downloaded the kernel source for your device from the HTCdev and found the function defined in drivers/media/video/msm/msm_camera-7×30.c Could check what are the kernel messages when you take a picture? adb shell su -c “dmesg”
I think this function is not passing the correct endpoint int status = connection.bulkTransfer(endpoint, getEvent, getEvent.length, TIMEOUT); which is coming from UsbInterface intf = device.getInterface(0); UsbEndpoint endpoint = intf.getEndpoint(0); maybe the USB interface is not correct. Please check if index 0 parameter is correct.
I had the same problem trying to implement OpenCV. I was able to fix it by making the following changes to the deliverAndDrawFrame method. Rotate the canvas object Canvas canvas = getHolder().lockCanvas(); // Rotate canvas to 90 degrees canvas.rotate(90f, canvas.getWidth()/2, canvas.getHeight()/2); Resize the bitmap to fit entire size of canvas before drawing // Resize Bitmap … Read more
If the image(photo) was taken by a program made by you, you must set Parameters.setRotation with the correct rotation value. This, depending of camera drive, rotates the image before save or save the rotation value to exif TAG_ORIENTATION. Therefore, if TAG_ORIENTATION is null or zero, the image are in the correct orientation, otherwise you must … Read more
