An imaging control device 100 includes a control communication unit 110 that communicates with a plurality of imaging devices and an overall control unit 101. The overall control unit 101 transmits an imaging preparation command to prepare imaging to each of the plurality of imaging devices 10 through the control communication unit 110 in response to an instruction received through an instruction receiving unit, receives preparation completion information indicating the completion of preparation for imaging from each of the plurality of imaging devices 10 through the control communication unit 110, and transmits a captured image acquisition command to acquire a captured image to each of the plurality of imaging devices 10 through the control communication unit 110 after receiving the preparation completion information from the plurality of imaging devices 10.

Various embodiments include a camera system having a tilt actuator arrangement for tilting an image sensor. For example, the tilt actuator may be used to tilt the image sensor, relative to a lens group of the camera system, to provide tilt compensation and/or optical image stabilization (OIS). The tilt actuator arrangement may include one or more voice coil motor (VCM) actuators. According to various embodiments, the VCM actuator(s) may include fixed drive magnets and movable drive coils. The drive magnets may be coupled with a housing of the camera system. The drive coils may be coupled with a substrate, and the substrate may also be coupled with the image sensor, such that the image sensor and the substrate move together.
