Abstract
A video camera includes a processor that is operable to obtain a capacity value of a battery by communicating over a communications line with a battery pack that contains the battery and which provides power to the video camera. The capacity value indicates a number of cell structures in the battery. The processor is also operable to set a correction value based on the capacity value, to correct a low power warning voltage value by subtracting the correction value from the low power warning voltage value, to generate a low power warning when a detected battery voltage is less than or equal to the corrected low power warning voltage value, and to generate a residual power indication when the detected battery voltage is greater than the corrected low power warning voltage value. A display is operable to display the low power warning or the residual power indication.
