  • Patent number: 10520552
    Abstract: An electronic device includes a processor coupled to a battery and to determine whether the battery is being charged or discharged. If the battery being is being discharged, the processor operates to calculate an amount by which the battery has discharged since a preceding calculation of remaining capacity of the battery, compensate the amount by which the battery has discharged for a condition of the battery, and calculate a remaining capacity of the battery as a function of the amount by which the battery has discharged. If the battery is being charged, the processor operates to calculate an amount by which the battery has charged since a preceding calculation of remaining capacity of the battery, compensate the amount by which the battery has charged for a condition of the battery, and calculate the remaining capacity of the battery as a function of the amount by which the battery has charged.

  • Patent number: 8085341
    Abstract: A digital camera has a battery that supplies electric power, a battery level detector, a time detector, a remaining voltage calculator, and a boot controller. When the digital camera is turned off, the battery level detector detects a remaining voltage level of the battery. When the digital camera is turned on, the time detector detects an elapsed time from the last electric power OFF operation to the current electric power ON operation, namely, a time period in which the camera is in the OFF state. Further, when the digital camera is turned on, the remaining voltage calculator calculates a remaining voltage-level of the battery on the basis of the detected elapsed time, the last detected remaining voltage level, and the discharge characteristic of the battery. Then, the boot controller allows the digital camera to boot if the calculated remaining voltage level is larger than a limited voltage necessary to boot the digital camera.

  • Patent number: 6434337
    Abstract: In a digital still camera equipped with a DAP (Digital Audio Player), the camera is so adapted that the camera can be used in a camera mode even when battery voltage declines owing to use of the camera in the DAP mode. The number of images to be recorded in the camera mode is set and so is a warning voltage necessary to record images of the set number. If battery capacity declines owing to operation in the DAP mode and the battery voltage reaches the set warning voltage, the user is notified of the fact that if use in the DAP mode is continued, it will not be possible to record the set number of images. By ceasing to use the camera in the DAP mode, a further decline in the capacity of the battery can be prevented. This makes it possible to reserve enough battery capacity to carry out the recording of the set number of images.
