Imaging device and control method therefor, and program for the same

Abstract

An imaging device includes measures to prevent it from becoming unusable due to battery discharge or no storage in the storage medium. The device includes a battery charge function and a data transfer function. After detecting the charge amount remaining in the battery and the remaining storage capacity in the storage medium, the order of priority for performing battery charge and data transfer is set. The imaging device is switched between the battery charge function and the data transfer function based on the set priority order. The battery charge is executed in accordance with the detected remaining charge and the data transfer in accordance with the detected remaining storage capacity.

1 . An imaging device including a battery charge function for charging a battery and a data transfer function for transferring data recorded in a storage medium to an external apparatus, the imaging device comprising:
 a remaining charge detecting unit configured to detect an amount of charge remaining in the battery;   a remaining storage capacity detecting unit configured to detect a remaining storage capacity available for recording data in the storage medium;   an operating unit configured to allow a user to select any mode among a charge prioritizing mode in which charging the battery is prioritized and a data transfer prioritizing mode in which transferring the data recorded in the storage medium to the external apparatus is prioritized; and   a control unit configured to control the charge prioritizing mode or the data transfer prioritizing mode according to the selected mode through the operating unit,   wherein the control unit is configured to provide a control of:
 when the amount of charge remaining detected by the remaining charge detecting unit is less than a prescribed charge value in a case where the charge prioritizing mode is selected, charging the battery until the amount of charge remaining reaches the prescribed charge value, and 
 when the remaining storage capacity detected by the remaining storage capacity detecting unit is less than a prescribed storage capacity value after the amount of charge remaining has reached the prescribed charge value, in a case where the charge prioritizing mode is selected, transferring data from the storage medium to the external apparatus until the remaining storage capacity reaches the prescribed storage capacity value. 
   
     
     
         2 . An imaging device including a battery charge function for charging a battery and a data transfer function for transferring data recorded in a storage medium to an external apparatus, the imaging device comprising:
 a remaining charge detecting unit configured to detect an amount of charge remaining in the battery;   a remaining storage capacity detecting unit configured to detect a remaining storage capacity available for recording data in the storage medium;   an operating unit configured to allow a user to select any mode among a charge prioritizing mode in which charging the battery is prioritized and a data transfer prioritizing mode in which transferring the data recorded in the storage medium to the external apparatus is prioritized; and   a control unit configured to control the charge prioritizing mode or the data transfer prioritizing mode according to the selected mode through the operating unit,   wherein the control unit is configured to provide a control of:
 when the remaining storage capacity detected by the remaining storage capacity detecting unit is less than a prescribed storage capacity value in a case where the data transfer prioritizing mode is selected, transferring data from the storage medium to the external apparatus until the remaining storage capacity reaches the prescribed storage capacity value, and 
 when the amount of charge remaining detected by the remaining charge detecting unit is less than the prescribed charge value after the remaining storage capacity has reached the prescribed storage capacity value, in a case where the data transfer prioritizing mode is selected, charging the battery until the amount of charge remaining reaches the prescribed charge value.
