摘要： A lens apparatus includes: an image pickup optical system; a holding frame that holds the image pickup optical system; and an illumination apparatus that is attached to an outer peripheral portion of an object side of the holding frame and applies light. The illumination apparatus includes light sources and a light guide member that causes internal reflection of light from the light sources so that the light propagates. The light guide member has an annular shape and has a light exit surface from which light is emitted toward an object side. A distance DL between two closest light sources in the light sources, an internal diameter D of the plurality of light guide member, and a distance WD from the light guide member to an object at a closest distance when the image pickup optical system is focused on the object at the closest distance are appropriately set respectively.

摘要： A camera system includes a lighting device comprising a movable unit including a flash unit, an imaging apparatus, a setting unit, an operation unit, and a control unit. The setting unit sets an irradiation position which is to be irradiated with light from the flash unit. The operation unit accepts an operation for starting photographing preparation operation. The control unit performs driving control of the movable unit. When the operation unit accepts an operation for starting photographing preparation operation, the control unit performs driving control of the movable unit for irradiating the set irradiation position with light from the flash unit. When the operation unit does not accept an operation for starting photographing preparation operation, the control unit does not perform driving control of the movable unit for irradiating the set irradiation position with light from the flash unit.

摘要： The invention relates to a method for the current limitation of a load current, in particular the load current of a flash means. In one step, first a supply voltage (VBAT) is provided. Then a load current (I) is set depending on the supply voltage (VBAT) for supplying the flash means (LED) with power by incrementally reducing the load current (I) until the supply voltage (VBAT) is greater than a threshold value (Vlow). The load current intensity (Imin) of the set load current (I) can be stored in a register (RAM) for the subsequent triggering of the flash means (LED) in a main flash phase (2) with the load current intensity (Imin) stored in the register (RAM). In addition, the invention relates to a circuit having current limitation of a load current of a flash means.

摘要： A handheld electronic device includes a processor; a battery; a flash device; a number of loads powered by the battery; and a flash driver outputting a flash current to the flash device. The processor determines a temperature operatively associated with the battery and different voltage values corresponding to different combinations of the loads as a function of the determined temperature, and starts the flash device at a predetermined flash current value. The flash driver selects a corresponding different voltage value as a function of: (a) a determined number of the loads which are active, or (b) a current flowing from the battery; determines the battery voltage, and if the battery voltage is less than or equal to the corresponding different voltage value, reduces the flash current below the predetermined flash current value until the battery voltage is greater than the corresponding different voltage value.
