1. An imaging apparatus, comprising:

  • circuitry configured to;

    calculate a usable time of at least one battery device comprising a secondary battery,measure an average power level while at least one component of the imaging apparatus performs at a predetermined operation mode, wherein the power consumption of the at least one component is unknown in advance before power is supplied and after the at least one component is initially connected to the imaging apparatus, andcalculate, when power is supplied for the second and subsequent times while the at least one component is continuously connected to the imaging apparatus, the usable time of the at least one battery device using the average power level and a current integration value, which is an integration value of current flowing.
