Abstract:
Offenbart ist eine Lichterfassungsvorrichtung (KM1)umfassend einen Lichtsensor (KA) mit einem elektronischen Kameraelement, das einen Aufnahmeabschnitt (AA) zum Aufnehmen von Licht, das von einer Lichtquelle abgestrahlt wird, aufweist; einem optischen Element (L) zum Brechen des von der Lichtquelle abgestrahlten Lichts, wobei das optische Element (L, PL) zwischen dem Aufnahmeabschnitt (AA) und der Lichtquelle angeordnet ist; und einem Absorptionselement (PSG), das zwischen dem Aufnahmeabschnitt und der Lichtquelle angeordnet ist, um die Intensität des bei dem Aufnahmeabschnitt auftreffenden Lichts zu steuern, wobei der Absorptionsgrad des Absorptionselements veränderlich ist. Zum Erreichen einer einfachen Möglichkeit der Steuerung des auf den Aufnahmeabschnitt des Kameraelements auftreffendes Lichts wird vorteilhafterweise das Absorptionselement aus einem phototropen Glas ausgebildet.
Abstract:
Some embodiments comprise at least one array that includes microelectromechanical systems ("MEMS")-based light-modulating devices. Elements of the array(s) may be configured to absorb and/or reflect light when in a first configuration and to transmit light when in a second position. Such an array may be controlled to function as a camera aperture and/or as a camera shutter. For example, a controller may cause the array to function as a shutter by causing the MEMS devices to open for a predetermined period of time. The predetermined period of time may be based, at least in part, on input received from a user, the intensity of ambient light, the intensity of a flash, the size of the camera aperture, etc. Some embodiments provide a variable aperture device that does not add significant thickness or cost to a camera module. Such embodiments may enable a camera to function well in both bright and dark light, to control depth of field, etc.
Abstract:
An imaging apparatus connectable to a client apparatus via a network includes an imaging optical system, an image sensor, an infrared cut filter (IRCF) driving circuit that inserts and retracts an IRCF into and from an optical path of the imaging optical system, and a communication circuit that receives, from the client apparatus, an automatic insertion and retraction control command for causing the imaging apparatus to automatically control insertion and retraction of the IRCF and additional information about insertion and retraction of the IRCF. The communication circuit transmits, to the client apparatus, operation information indicating which of cases the imaging apparatus uses the additional information received by the communication circuit. The cases include a case where the IRCF is inserted into the optical path, a case where the IRCF is retracted from the optical path, and both the cases where the IRCF is inserted and where the IRCF is retracted.
Abstract:
A device for switching optical filters of a camera constantly provides clear images during the day and night. A lens (1a) mounted on a camera body (1) forms an image on an imaging device (2), which in turn converts the image into an electric signal to obtain an image signal. Means (3) for switching optical filters (3a, 3b) depending on the level of the image signal is provided in front of the imaging device (2). The camera can be advantageously used in a monitoring system to improve reliability since it provides clear images during the day and night.
