1. A risk evaluation system comprising: (4) (2)

an imager that takes images at different times of equipment having zones that do not overlap each other, and outputs the images that are taken; and

a controller that detects a contact count of a number of times a living body contacts each of the zones in accordance with the images, decides evaluation information about a contact infection risk in each of the zones in accordance with the contact count, and outputs the evaluation information.

2. The risk evaluation system according to claim 1, wherein (1) (2)

the controller additionally computes, for each zone, a risk value indicating how high the contact infection risk is in accordance with a number of times contact occurs, and

the evaluation information includes the risk value that is computed.

3. The risk evaluation system according to claim 2, wherein (1) (1)

5. The risk evaluation system according to claim 1, wherein (1) (1)

the controller additionally (i) determines whether or not detected contact with one of the zones by the living body is contact associated with cleaning work, and

(ii) in a case of determining that the detected contact with one of the zones by the living body is the contact associated with the cleaning work, the controller resets the contact count of the zone to 0.

6. The risk evaluation system according to claim 5, wherein (0) (1)

7. The risk evaluation system according to claim 1, further comprising: (1) (2)

9. The risk evaluation system according to claim 1, further comprising: (1) (2)

a detector that detects contact by the living body with each of the zones in the equipment having the zones that do not overlap each other, wherein

the controller decides the evaluation information about the contact infection risk in each of the zones in accordance with a number of times the contact by the living body is detected by the detector.

10. The risk evaluation system according to claim 9, wherein (1) (2)

the detector includes a distance sensor that detects a distance to the living body contacting a surface of the equipment, and

the controller specifies the contact by the living body and one of the zones that the living body is contacting in accordance with the distance that is detected.

11. The risk evaluation system according to claim 10, wherein (1) (1)

the distance sensor is optical distance sensor that emits a light beam along the surface of the equipment, and detects the distance to the living body contacting the surface according to the light beam.

12. The risk evaluation system according to claim 11, wherein (0) (2)

13. A risk evaluation method comprising: (0) (2)

14. A non-transitory computer-readable recording medium storing a program causing a computer to execute a risk evaluation method, the risk evaluation method comprising: (0) (2)
