A method and apparatus for determining a viewpoint, an electronic device, and a computer program product. The method comprises: obtaining imaging positions of a user's eyeballs in an image sensor of an infrared camera and rotation angles of the user's eyeballs; determining the distance between the user's eyeballs and a lens of the infrared camera; determining the positions of the user's eyeballs according to the imaging positions and the distance; and determining the viewpoint position of the eyeballs according to the positions of the user's eyeballs and the rotation angles.
