  While the novel applications of weak values have recently attracted wide
attention, weak measurement, the usual way to extract weak values, suffers from
risky approximations and severe quantum noises. In this paper, we show that the
weak-value information can be obtained exactly in strong measurement with
postselections, via measuring the coupling-deformed pointer observables, i.e.,
the observables selected according to the coupling strength. With this
approach, we keep all the advantages claimed by weak-measurement schemes and at
the same time solve some widely criticized problems thereof, such as the
questionable universality, systematical bias, and drastic inefficiency.
