Abstract
A method for obtaining, for at least one pixel of an image sensor comprised in an optical device, parameters defining a pixel beam is described. The method is remarkable in that it includes determining a direction of a chief ray associated with at least one pixel of the image sensor from the features of an optical system associated with the optical device, determining a set of pixels formed in a screen of a display device, the set of pixels comprising at least one pixel close to a point corresponding to an intersection of the chief ray and the screen, and the set of pixels comprising only pixels which are detected by the at least one pixel of the image sensor, when they are illuminated.
