The invention relates to a filtering control method and device and electronic equipment and provides an information processing method and device. A biological feature collecting module with an optical function unit is arranged in the electronic equipment, the optical function unit has a first state and a second state, and the optical parameter of the optical function unit in the first state is different from that of the optical function unit in the second state. When different shooting modes are switched, voltage signals are generated through operations which a user carries out on the electronic equipment, the operations correspond to different target work states of the biological feature collecting module, and the optical function unit is controlled to be switched between the first state and the second state according to the voltage signals. The invention further provides a structure of the optical function unit. Due to the fact that the information processing method is adopted, the optical function unit does not need to be moved in the state switching process of the optical function unit, a matching structure of the optical function unit also does not need to be moved, the size needed by a filtering structure is reduced, and accordingly the size of the electronic equipment can also be correspondingly reduced.
