Abstract
A method and apparatus are disclosed. The method may include determining a current zoom value of a camera and determining a first modulation transfer function of a transparent dome of the camera. The method may include applying a first low-pass filter to an image captured by the camera based on the current zoom value and the first modulation transfer function of the transparent dome.
