Opencv Camera megapixels Android

i am new with Opencv.I use JavaCameraView, which uses 1280x 720 camera resolution. How can I increase the resolution to 5 megapixels? Please help me :)

Solution

  • You need to pick a resolution that is allowed by your camera. Call the following code in your onCameraViewStarted function and set listNum so that it corresponds to the resolution you desire:

    Parameters params = mCamera.getParameters();
List<Size> resList = mCamera.getParameters().getSupportedPictureSizes();
int listNum = 1;// 0 is the maximum resolution
int width = resList.get(listNum).width;
int height = resList.get(listNum).height;
params.setPictureSize(width, height);
mCamera.setParameters(params);

    mCamera is your org.opencv.android.JavaCameraView object.
