To provide a technique for work information processing insensitive to the environment of measurement, because the existing technique of measuring movements of workers or others through cameras or others and analyzing the working movements to improve the workers' working efficiency requires cameras or other optical devices to image workers' movements, and is incompatible with, for example, work measurement in dark places or obstacles present between cameras and subjects.

A detection information processing apparatus 100 changes the length of a time axis such that values detected by various sensors 161A and 161B are matched with standard detected values until finding the time axis length of the best matching to associate the detected values and the standard detected values on the time axis, and specifies and displays time deviation.
