Abstract

A method of operating a handheld camera comprises sensing an image via an image sensor, controlling the sensing of the image via a camera manager, manipulating the image via an image processing manager, and controlling printing of the manipulated image via a print manager. The step of controlling printing of the manipulated image includes causing the print manager to activate a guillotine, which guillotine is adapted to cut a print media, upon receipt of a signal indicative of an attempt to pull the print media from the camera.

Claims

1. A method of operating a handheld camera, the method comprising:

sensing an image via an image sensor;

controlling the sensing of the image via a camera manager;

manipulating the image via an image processing manager; and

controlling printing of the manipulated image via a print manager, wherein

the step of controlling printing of the manipulated image includes causing the print manager to activate a guillotine, which guillotine is adapted to cut a print media, upon receipt of a signal indicative of an attempt to pull the print media from the camera.

2. A handheld camera as claimed in claim 1, further comprising a print roll sensor adapted to detect an attempt to pull media from the camera.

3. A handheld camera as claimed in claim 2, wherein the roll sensor is a strain gauge sensor.
