I searched for past two days and i was not successful yet .

I my case , i want to check the camera pixel resolution/Megapixels . If the camera's Mp is more than 4 then i need to re-size and upload .

Here is my code :

//to check the resolution

Camera mcamera ;

mcamera = Camera.open(Camera.CameraInfo.CAMERA_FACING_BACK);

Camera.Parameters param = mcamera.getParameters();
Camera.Size size = param.getPictureSize();

cam_height = size.height ;
cam_width = size.width ;

mcamera.release();

// my functionality

BitmapFactory.Options resample = new BitmapFactory.Options();
if(cam_height > pict_height || cam_width > pict_width )
    resample.inSampleSize = 2;  // whatever number seems appropriate 2 means 1/2 of the original
else
    resample.inSampleSize = 1;

capturedimg = BitmapFactory.decodeFile(fileUri.getPath() , resample);
resized_uri = bitmaptouri(capturedimg);

but this returns only the picture resolution which is the same as the Screen resolution of the mobile but i want the Mobile camera's resolution .

Any related answers are welcomed , Thanks in advance .

  • you mean mega pixels.?? – Sagar Maiyad Jun 20 '13 at 04:46
  • Can't you get the number of pixels in the image and resize based on that? – joshuahealy Jun 20 '13 at 04:46
  • @segi : either mega pixel or resolution , but i want the camera's not the mobile screen's . – VIGNESH Jun 20 '13 at 04:47
  • @appclay : bro. i want to get the camera's resolution , if get the resolution of the image , after capturing it will be the screen's resolution not the camera's resolution . – VIGNESH Jun 20 '13 at 04:50
  • You can use Parameters.getSupportedPictureSizes() to get all actual supported picture sizes, find the one that is the largest and do whatever you desire to do with it. – Milan Jun 20 '13 at 04:52

How about getSupportedPictureSizes()?

First find height and width like below:

android.hardware.Camera.Parameters parameters = camera.getParameters();
android.hardware.Camera.Size size = parameters.getPictureSize();


int height = size.height;
int width = size.width;

then get mega pixel using below equation:

int mg = height * width / 1024000;

where mg is your mega pixels.

First check the supported picture sizes available for the Camera using Camera.Parameters. There is a function called getSupportedPictureSizes() in Camera Parameters.

For e.g: 

List<Camera.Size> mList    =    mParams.getSupportedPictureSizes();
Camera.Size mSize          =    mList.get(mList.size() - 1);

From the mList you get all the supported Picture Sizes. The final one in the list will be the largest possible resolution.

Try the code from here. It returns resolution in mp for back camera. You should use getSupportedPictureSize instead of getPictureSize
