摘要:
A zero point adjustment is performed by generating no signal state of a CCD camera. A state in which stray light does not enter the CCD camera is ensured by a calibration shutter. An output signal of the CCD camera is transmitted to a light amount calculator, and a calibrating section executes a calibration for the light amount calculator by using an output signal value as a reference (zero point). Further, light outputted from a laser light source is attenuated by an optical attenuator and is made to be incident on the CCD camera. By switching an attenuating amount of the optical attenuator, correctly set light is made to be incident on the CCD camera. The output signal of the CCD camera is transmitted to the light amount calculator, and the calibrating section executes the calibration such that values of the respective output signals correctly correspond to respective light amounts.

Dans les appareils de prise de vues, la mesure de la lumiere traversant l'objectif fournit seulement une indication de la lumiere reflechie. L'accessoire de filtre de lumiere pour appareil de prise de vues decrit permet de mesurer la lumiere incidente en utilisant le circuit de mesure de l'appareil sur lequel il est monte. Le filtre de lumiere comprend une demi-sphere translucide (12) en saillie sur une plaque (8). La plaque (8) possede une partie centrale (9) translucide et une partie (13) filetee permettant de fixer le filtre sur l'objectif (34).

A method (800) of adjusting electromagnetic radiation transmitted by an optical element (250) is described. The method includes sensing (830) the electromagnetic radiation transmitted by the optical element to produce sensed electromagnetic radiation information (615), and adjusting (835) the sensed electromagnetic radiation information to produce adjusted electromagnetic radiation information (620) based on the a spectral transmission of the optical element.

Eine Vorrichtung zur selektiven Lichtmessung für photographische Zwecke, (Handbelichtungsmesser) besteht aus einem optischen Suchersystem, einem Okular, einer Objektivlinse sowie optischen Umlenkelementen zum Aufsuchen und Abtasten eines photographischen Objektes sowie einer in einem Gehäuse angeordneten Meßvorrichtung, mit der eine elektronische Meßwerterfassung und - verarbeitung sowie eine Anzeigevorrichtung verbunden ist. Sie soll derart weitergebildet werden, daß sie eine kontinuierliche Erfassung der Meßwerte beim Betrachten des photographischen Objektes durch den Sucher ermöglicht, klein und robust aufgebaut und damit leicht handhabbar ist, sowie eine wirklich umfassende Information über alle photographisch relevanten, Beleuchtungsdaten ermöglicht. Dies wird dadurch erreicht, daß das Suchersystem 2, der lichtempfindliche Sensor 14, die Meßwerterfassung 14a, 14b und die Meßwertverarbeitung 14c, sowie die als Flüssigkristallanzeige 15 ausgebildete Anzeigevorrichtung in einem zweischaligen Gehäuse 9 angeordnet sind und die Anzeigevorrichtung sämtlicher Meß- und Funktionswerte Anzeigeelementen der im Strahlengang liegenden Flüssigkristallanzeige 15 besteht. Sie sind optisch um die Abbildung des Meßfeldes herum angeordnet und beim Anvisieren des Meßfeldes gleichzeitig ablesbar.
