Im studying OpenCV using a webcam C920. This webcam has resolution 1920x1080. In webcam specifications says that C920 can capture imagens with 15mp. Using OpenCV to capture images, a picture has 2mp. Using Logitech application a picture has 15MP.
My doubts:
How its possible capture images with 15mp with resolution 1920x1080? Is the image enlarged?
Is it possible capture images with 15mp using OpenCV?
Images enlarged:

Optical Resolution True:3MP Software Enhanced:15MP
i'm guessing the software is up scaling the image and performing some kind of interpolation between the pixels.
