Method allowing matching between an actual position of a shutter of a motorized shutting device (610, 620) and a controlled position of said shutter, the controlled position being associated with a value of a control parameter for the motorized shutting device, the method being performed by an electronic device (400, 630, 640) and by a user, the electronic device comprising: - a screen allowing the display of a graphical interface, - an input device allowing a user to interact with the displayed graphical interface, the method comprising, in a parameterization phase, the steps of: - displaying, as an overlay in the graphical interface: ∘ a first reference corresponding to a "bottom" portion of the motorized shutting device, ∘ a second reference corresponding to a "top" portion of the motorized shutting device, ∘ a third reference corresponding to a predetermined first actual position of the shutter, characterized in that said electronic device comprises: - a digital still camera allowing the capture of an image, and in that said method comprises, in said parameterization phase, the steps of: - displaying, as an overlay in the graphical interface an image of the motorized shutting device captured by the digital still camera, the shutter being in a second position, - the user directing the still camera so that the first and second references correspond to the "bottom" and "top" portions of the motorized shutting device, and then - the user moving the third reference so as to match it up with the second actual position of the shutter displayed as an overlay or the user actuating the shutter so as to match its second actual position up with the third reference displayed as an overlay, - receiving, via the input device, a validation message, the validation message signifying that the overlayed display of the first reference, of the second reference and of the third reference coincides respectively with the "bottom" portion of the motorized shutting device, the "top" portion of the motorized shutting device and the second actual position of the shutter in the image displayed as an overlay, - determining a value of the control parameter for the motorized shutting device associated with the controlled position of the shutter, - determining parameters of a matching function between an actual position of the shutter and a controlled position of the motorized shutting device according to the first actual position and the value of the previously determined control parameter. - a screen allowing the display of a graphical interface, - an input device allowing a user to interact with the displayed graphical interface, - displaying, as an overlay in the graphical interface: ∘ a first reference corresponding to a "bottom" portion of the motorized shutting device, ∘ a second reference corresponding to a "top" portion of the motorized shutting device, ∘ a third reference corresponding to a predetermined first actual position of the shutter, ∘ a first reference corresponding to a "bottom" portion of the motorized shutting device, ∘ a second reference corresponding to a "top" portion of the motorized shutting device, ∘ a third reference corresponding to a predetermined first actual position of the shutter, - a digital still camera allowing the capture of an image, - displaying, as an overlay in the graphical interface an image of the motorized shutting device captured by the digital still camera, the shutter being in a second position, - the user directing the still camera so that the first and second references correspond to the "bottom" and "top" portions of the motorized shutting device, and then - the user moving the third reference so as to match it up with the second actual position of the shutter displayed as an overlay or the user actuating the shutter so as to match its second actual position up with the third reference displayed as an overlay, - receiving, via the input device, a validation message, the validation message signifying that the overlayed display of the first reference, of the second reference and of the third reference coincides respectively with the "bottom" portion of the motorized shutting device, the "top" portion of the motorized shutting device and the second actual position of the shutter in the image displayed as an overlay, - determining a value of the control parameter for the motorized shutting device associated with the controlled position of the shutter, - determining parameters of a matching function between an actual position of the shutter and a controlled position of the motorized shutting device according to the first actual position and the value of the previously determined control parameter.
