Abstract
A battery property judging circuit measures a voltage of battery before and while a zoom motor is operated respectively. A type of the battery is determined by a voltage change of the battery. A CPU selects either one of a normal operation sequence or a power-saving operation sequence in accordance with the type of battery upon carrying out an operation mode. In the normal operation sequence, whose operation mode is zooming or focusing, the zoom motor and an AF motor are simultaneously driven so as to perform zooming and focusing, whereas in the power-saving operation sequence, zooming first, then focusing is performed.
Claims9
A digital camera being driven by a battery comprising:
- a judging circuit for determining a property of said battery;
