Title (EN) METHOD FOR CALIBRATING A SPECTRUM OBTAINED USING AN ELECTRONIC DEVICE EQUIPPED WITH A REMOVABLE ACCESSORY
(FR) PROCEDE D'ETALONNAGE D'UN SPECTRE OBTENU A L'AIDE D'UN APPAREIL ELECTRONIQUE EQUIPÉ D'UN ACCESSOIRE AMOVIBLE
Abstract:
(EN) The invention relates to a method implemented in a system (1000) comprising: an electronic device (600), such as a mobile telephone or a digital tablet, comprising, in particular, a colour photosensitive multi-pixel sensor; and a removable accessory (100) comprising a casing (110) secured to the electronic device, said casing receiving wavelength dispersion means and beam rectification means. The method according to the invention is implemented by computation means (603) belonging to the electronic device (600) and comprises, in particular, a preliminary step of determining wavelength calibration data, with an adjustment step comprising the following sub-steps of: receiving an adjustment image supplied by the photosensitive multi-pixel sensor (601); searching for a region having a minimal difference in light intensity, measured on two neighbouring pixels each associated with the detection of a different wavelength; and, based on a comparison between the first wavelength calibration data and the position of said region in the adjustment image, determining second wavelength calibration data.
(FR) L'invention concerne un procédé mis en œuvre dans un système (1000) comprenant : - un appareil électronique (600) tel qu'un téléphone portable ou une tablette numérique, comportant notamment un capteur multi-pixels photosensible couleur; et - un accessoire amovible (100) comportant un boîtier (110) fixé à l'appareil électronique, le boîtier recevant des moyens de dispersion en longueur d'onde et des moyens de redressage de faisceau. Le procédé selon l'invention est mis en œuvre par des moyens de calcul (603) de l'appareil électronique (600), et comprend notamment une étape préliminaire de détermination de données d'étalonnage en longueur d'onde, avec une étape d'ajustement comprenant les sous-étapes suivantes : - réception d'une image d'ajustement fournie par le capteur multi-pixels photosensible (601); - recherche d'une région dans laquelle une différence d'intensité lumineuse, mesurée sur deux pixels voisins associés chacun à la détection d'une longueur d'onde différente, est minimale; - à partir d'une comparaison entre des premières données d'étalonnage en longueur d'onde, et la position de ladite région sur l'image d'ajustement, détermination de secondes données d'étalonnage en longueur d'onde.
