Patent ID: 7961248

Claim:
An image pickup apparatus comprising: an additional function setting unit configured to turn on or off an additional function of the image pickup apparatus; a computing unit that (a) computes a first current consumption integrated value required for capturing a single image when the additional function is on, (b) computes, using the first current consumption integrated value and a remaining capacity of a battery, the number of images that can be captured by the image pickup apparatus, (c) computes a second current consumption integrated value required for capturing a single image when the additional function is off, and (d) computes, using the second current consumption integrated value and the remaining capacity of the battery, the number of images that can be captured by the image pickup apparatus; and a display unit that (a) displays first battery information when the additional function is on and (b) displays second battery information when the additional function is off, wherein the first battery information includes first information corresponding to the first current consumption integrated value computed by the computing unit, second information corresponding to the number of images computed by the computing unit using the first current consumption integrated value and the remaining capacity of the battery, and third information corresponding to the remaining capacity of the battery, and wherein the second battery information includes fourth information corresponding to the second current consumption integrated value computed by the computing unit, fifth information corresponding to the number of images computed by the computing unit using the second current consumption integrated value and the remaining capacity of the battery, and sixth information corresponding to the remaining capacity of the battery.
