Abstract
A storage device includes a first storage that stores an image of a machine captured by an imaging device in association with time information indicating a timing at which the machine is imaged, and a second storage that stores control information for controlling the machine. The second storage stores the control information in association with the time information, the control information corresponding to a timing at which a control device that controls the machine acquires the time information from the imaging device.
Claims17
1:
- A storage device comprising:
- a first storage to store a plurality of images of a machine captured by an imager, in association with a plurality of pieces of time information each indicating an elapsed time from a reference time;
