Multiple viewpoint image capturing system, three-dimensional space reconstructing system, and three-dimensional space recognition system

A calibrator for cameras, comprising:

• communication interface circuitry to be connected to the cameras and to at least one sensor provided for the cameras;
• and
• processing circuitry configured to:
• control the communication interface circuitry to receive, from the at least one sensor, sensed information;
• calculate order of recalibration processes of the respective cameras based on the sensed information;
• and
• control the communication interface circuitry to send instructions such that the recalibration processes are sequentially performed in the order,
• wherein the cameras include a first camera and a second camera, and
• wherein the order is calculated such that the recalibration process of the first camera is performed prior to the recalibration process of the second camera.
