The present invention is a system and method of operating cellular devices in a synchronized manner. Each of a plurality of mobile cellular devices has a system clock, a display screen, and a camera flash, and each mobile cellular device communicates with a communications network. A software application is loaded onto each of the cellular devices. A primary user selects a session activity that is to be performed by the cellular devices. The cellular devices first update system time to improve time synchronization. At an execution time, a session activity is performed simultaneously by all the mobile cellular devices.

There is provided a control device, a control method, and a program through which it is possible to implement a more suitable imaging environment even under a situation in which auxiliary light is emitted from a plurality of light sources, the control device including: an acquisition unit configured to acquire a light emission state of a first light source; and a control unit configured to control an operation of light emission of a second light source that is different from the first light source according to the acquired light emission state of the first light source.

A mobile photography studio for photographing objects. The studio has a main trailer body having an internal volume defined by a roof, a floor, a front wall, a rear wall, and two side walls. A control computer controls an expansion of the sidewalls of the trailer, and optionally the roof, to expand the internal volume of the trailer. A turntable, which is disposed on the trailer floor supports and rotates the object based on commands from the control computer. At least one camera takes photographs of the object on the turntable based on commands from a camera control computer. A plurality of lights illuminate the object on the turntable based on commands from the control computer. The camera control computer controls the camera(s), and stores and processes the photographs.

The present disclosure relates to an imaging system and a control method that make it possible to implement setting for an external flash by an operation on a camera side. Setting coordination processing is executed in which setting information of an external flash (13) is transmitted and received between a first communication unit (67A) and a second communication unit (47). Further, a second display unit is caused to display a setting screen to be used for setting a setting item of the external flash, and the setting information changed by an operation on the second operation unit is caused to be transmitted from the imaging device (12) to the external flash (13) via the first communication unit (67A) and the second communication unit (47), and a setting for the external flash (13) is caused to be applied.

The present invention generally relates to the field of communication between electronic devices used for photography. In particular, the invention relates to a method, transmission unit, system and computer program for wireless communication between a camera and at least one remote flash device, such as photoflash units and related equipment. More in particular, the invention provides a way of controlling a plurality of flash devices from an intermediate radio transmission unit mountable on the camera, and utilized a delay a sequence flash control sequence so as to synchronize the function of the camera and the remote flash devices during image acquisition. Further the invention provides a way of controlling in the photoflash units settings for the main flash, wherein the setting are the last settings determined by the camera when the intermediate radio transmission unit was in a TTL-mode.

There is provided a control device, a control method, and a program through which it is possible to implement a more suitable imaging environment even under a situation in which auxiliary light is emitted from a plurality of light sources, the control device including: an acquisition unit configured to acquire a light emission state of a first light source; and a control unit configured to control an operation of light emission of a second light source that is different from the first light source according to the acquired light emission state of the first light source.

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 technique in multi-light control capable of notifying an image pickup apparatus of charge completion information items of a plurality of lighting devices. A lighting device is wirelessly communicably connected to other lighting devices, and is communicably attached to an image pickup apparatus so as to be driven in synchronism with the other lighting devices. First charge completion information of the lighting device itself and second charge completion information of the other lighting devices are transmitted to the image pickup apparatus either in a combined state or in a separate state. If it is determined that an instruction for transmitting the first charge completion information and the slave charge completion information in the separate state has been received from the image pickup apparatus, the first charge completion information and the slave charge completion information are transmitted to the image pickup apparatus in the separate.
