1. A power transmitting apparatus comprising:
a power transmitting unit configured to transmit power wirelessly to one or more power receiving apparatuses;
a communicating unit configured to communicate with the one or more power receiving apparatuses;
a deriving unit configured to derive data corresponding to a reference for power loss between the power transmitting apparatus and a power receiving apparatus on a basis of a value of reception power received from the power receiving apparatus via the communicating unit;
an object detecting unit configured to detect an object different from the power receiving apparatus performing communication on a basis of the data corresponding to the reference for power loss; and
a detecting unit configured to detect a change in a power transmission and reception state in a power-transmittal range of the power transmitting apparatus, wherein
when a change in the power transmission and reception state is detected by the detecting unit during power transmission by the power transmitting unit to the power receiving apparatus, the deriving unit re-derives the data corresponding to the reference for power loss,
wherein, during power transmission by the power transmitting unit to the power receiving apparatus, in a case where a change in the power transmission and reception state detected by the detecting unit is a change in a number of power receiving apparatuses in the power-transmittal range, the deriving unit re-derives the data corresponding to the reference for power loss.
