1. A control device connectable to a control-target machine and an imaging device to control the control-target machine, the control device comprising:
a first receiver circuitry to repetitively receive pieces of image data each indicating an image captured by the imaging device and related to control of the control-target machine, the piece of image data containing a first timestamp indicating an elapsed time since a specific time in association with the image;
a second receiver circuit to receive a piece of communication data related to a history of communication at the imaging device, the piece of communication data containing a second timestamp indicating an elapsed time since the specific time and a piece of transmission time data indicating a transmission time of transmission of the piece of communication data; and
processing circuitry to cause a storage to store a piece of association data indicating a corresponding time in association with the image, the corresponding time corresponding to the first timestamp and being calculated by subtracting the elapsed time indicated by the second timestamp from the elapsed time indicated by the first timestamp and then adding a difference resulting from the subtraction to the transmission time, the first timestamp being associated with the image indicated by the image data, the second timestamp corresponding to the transmission time, or being calculated by adding a predetermined correction term to a result of the addition, the predetermined correction term compensating for a time difference between a time corresponding to the first timestamp and a time of image capture at the imaging device.
