<p>A camera (500) that includes a battery (502), a photoflash circuit (512), and a charging circuit (510) to provide energy from the battery to the photoflash circuit is provided. The camera further includes a voltage monitor (506) coupled to the battery to switch off the battery from the charging circuit when a voltage on the battery falls below a predetermined voltage value. The camera may also include a current monitor (505), coupled to the battery, to switch off the battery from the charging circuit when a current generated through the battery exceeds a predetermined current value.</p> |
