The flash housing further comprises a zoom element rotatably arranged at least partly along the circumference of the lens element. The zoom element is operatively connected to the flash forming element so as to control movement of the flash forming element by manual rotation of the zoom element.

An image capturing apparatus comprises a communication unit that performs wireless communication with a plurality of light emitting apparatuses and a control unit that switches to a first communication state in which the plurality of light emitting apparatuses and the image capturing apparatus perform wireless communication at predetermined communication intervals, and a second communication state in which a predetermined light emitting apparatus of the plurality of light emitting apparatuses and the image capturing apparatus perform wireless communication at predetermined communication intervals and the predetermined light emitting apparatus and a light emitting apparatus other than the predetermined light emitting apparatus perform wireless communication at variable communication intervals. The control unit switches to the first communication state or the second communication state according to an operational state of the image capturing apparatus.

The invention relates to a control module for a camera and an illumination apparatus, a camera, a production system and a method for acquiring images by means of such a camera. The exposure times and illumination times are controlled on the basis of a common control clock signal. Due to this, beats can be avoided. This even applies if short flashes are executed at irregular times.

An imaging system includes a digital camera and illuminating devices. The digital camera includes an imaging optical system, a shutter, a shutter driving mechanism, an imaging element, an illumination control unit, and a wireless I/F. The shutter is a focal-plane shutter. In a case in which a main imaging operation is performed in a plural illumination control mode, the shutter driving mechanism drives the shutter to generate a transition period for which a partial exposure region is transferred to the lower side of an imaging area of the imaging element over time. The illumination control unit controls the emission times of the illuminating devices to be different times within the transition period.

A semiconductor light source includes at least one first emission unit, at least one second emission unit, and an optics, wherein the optical system has an inner region that converges radiation from the first emission unit, the optical system has an outer region that expands radiation from the second emission unit, a first light emission region of the inner region completely covers the first emission unit when viewed in plan view, and at least partially covers the second emission unit, a second light emission region of the outer region is partially or completely beside the second emission unit when viewed in plan view, and the inner region and the outer region have differently shaped light entry regions.
