  • this optical tool 310 comprises a hollow cylinder in which the light sensor is located.

  • AF active and passive auto-focus
  • Active AF systems measure distance to an object independently of the optical system, and subsequently adjust the optical system for correct focus.
  • Various ways exist to measure distance including ultrasonic sound waves and infrared light. In the first case, emitting sound waves and measuring the delay in their reflection allows calculating the distance to the object. The latter case employs infrared light to triangulate the distance to the object.
  • Passive AF systems determine correct focus by performing passive analysis of the image that enters the optical system. They generally do not direct any energy, such as ultrasonic sound or infrared light waves, toward the object. Passive AF systems typically apply phase detection or contrast measurements.

Abstract

La présente invention a trait à un dispositif de commande à distance (100) pouvant être utilisé dans un système d'éclairage (1). Ce système comprend une pluralité d'agencements lumineux (10) capables de créer un effet de lumière. Le dispositif de commande à distance comprend des moyens de communication (200) permettant d'établir une interaction avec le système d'éclairage (1) en pointant sur un emplacement (40) autour duquel l'effet de lumière doit être contrôlé. Les moyens de communication (200) comprennent un ensemble (300) permettant de régler la zone de contrôle de l'effet de lumière (50) autour de l'emplacement (40) sur lequel l'effet de lumière est contrôlé. Pour ce faire, l'ensemble peut comprendre un outil optique (310), tel que, par exemple, un élément réglable permettant d'arrêter les faisceaux, une lentille réglable ou un cylindre d'une longueur réglable. Ceci est tout particulièrement avantageux, car un utilisateur peut, par exemple, sélectionner un groupe réglable d'agencements lumineux simultanément.
