[Problem] To enable imaging to be performed with appropriate timing.

[Solution] In a camera manipulation device 1 according to the present invention, a trigger signal T12 is issued and imaging is begun when a prescribed command is transmitted from a control circuit side to an imaging unit side (see S12). Because the issuance of such trigger signal T12 is not accepted before a character reception start command is issued, it is possible to perform imaging with appropriate timing.

A hand-held device with a sensor for providing a signal indicative of a position of the hand-held device relative to an object surface enables power to the sensor at a first time interval when the hand-held device is indicated to be in a position that is stationary and adjacent relative to the object surface, enables power to the sensor at a second time interval shorter than the first time interval when the hand-held device is indicated to be in a position that is moving and adjacent relative to the object surface, and enables power to the sensor at a third time interval when the hand-held device is determined to be in a position that is removed relative to the object surface.

The drone comprises M antennas, with in particular two offset antennas located symmetrically at the ends of two arms for the connection to the propulsion units (24), and a ventral antenna under the drone body. The radio transmission is operated simultaneously on N similar RF channels, with 2?N<M. An antenna switching circuit couples selectively each of the N RF channels to N antennas out of the M antennas according to a plurality of different coupling schemes, dynamically through a piloting logic selecting one of the coupling schemes. The selection is operated as a function of a signal delivered by the drone-borne microprocessor, as a function of the flight and signal transmission conditions, determined at a given instant.
