PROBLEM TO BE SOLVED: To correct a displacement of impact mark displayed in response to a true impact point and a detected impact point.SOLUTION: Four small targets 202 enclosing a calculated impact point are specified and amounts of motion corresponding to each of the small targets are processed with weighted mean in response to distances Δx,Δy between the impact point and each of the small targets to calculate the corrected value, the calculated correction values are added to correct the calculated impact point. This invention can be applied to a target system for a soft air-gun capable of shooting BB bullet, for example.SELECTED DRAWING: Figure 25 |
