1. A camera for use with a power supply, the camera comprising:
- a voltage detecting circuit adapted to detect a voltage level at the power supply and to generate a voltage level signal;
an image capture system for performing a set of power-consuming image capture operations; and
a controller that prevents the image capture system from performing the set of image capture operations when the voltage level signal indicates there is power available in the power supply which is less than sufficient to perform all of the operations in the set of image capture operations, whereby the camera is rendered inactive before the power supply has practically run out of power.

Abstract
In one aspect of the invention, a camera for use with a power supply is provided. The camera has a voltage detecting circuit adapted to detect a voltage level at the power source and to generate a voltage level signal. An image capture system is also provided and performs a set of image capture operations. A controller receives the voltage level signal and prevents the image capture system from capturing an image when the voltage level signal indicates that there is insufficient power available in the power supply to perform all of operation in the set of image capture operations.

9. A camera for use with a power supply, the camera comprising:
-
an image capture system for performing a set of power-consuming image capture operations; a controller for commanding the image capture system to perform the set of image capture operations; a shutter trigger input for generating a shutter trigger signal; and a voltage detecting circuit for detecting a voltage level at the power supply that is sufficient for the image capture system to perform all of the operations in the set of image capture operations, which is activated by the shutter trigger signal, and which provides an enablement signal to the controller to instruct the controller to command the image capture system to perform the set of image capture operations when the power available in the power supply is sufficient for the image capture system to perform all of the operations in the set, but which does not provide the enablement signal to the controller when there is power available in the power supply that is sufficient to perform only some of the operations in the set. - View Dependent Claims (10)

11. A camera for use with a power supply, the camera comprising:
-
a voltage detecting circuit adapted to monitor voltage level at the power supply and to generate a voltage level signal; an image capture system for performing a set of power-consuming image capture operations that capture an image on an image receiving medium; and a controller that receives the voltage level signal at the time when a user requests irrevocably that an image be captured on the image receiving medium, using the image capturing system to perform the set of image-capture operations, but which prevents the image capture system from performing all of the operations in the set when the voltage level signal indicates there is power available in the power supply to perform only some of the operations in the set.
