Reprocessing of the light radiated from a companion star by the inner part of an accretion disk around a Schwarzschild black hole is modeled. Because of the aberration between the local static frame and the comoving frame of the disk, the infalling photons are seen by the disk to come mainly from the direction of the vertex of orbital motion, and the reradiated light is beamed into the direction of the disk's velocity. As in the case of inverse Compton scattering, the frequency of the reflected photons can be increased and the energy (and angular momentum) from the disk can be extracted. The efficiency of this process is dependent on the geometry of the system. The infalling flux can be amplified by a factor of order unity in the vicinity of the marginally stable orbit. Despite the fact that the loss of energy is negligible for realistic intensities of the infalling flux, the effect is interesting in principle, and it can play a role in the modeling of observable effects in accreting systems like low-mass X-ray binaries, as well as active galactic nuclei.
