Abstract
An electronic device includes an illuminating unit, an image-capturing unit and a control unit. The illuminating unit includes a light source and an optical element and is configured to generate a reference pattern at the exit of said optical element. The control unit is configured to analyze an image captured by the image-capturing unit. The control unit is configured to identify the reference pattern generated by the illuminating unit in the image captured by the image-capturing unit. A method to verify the presence of an optical element within such an electronic device is also described.
Claims15
An electronic device comprising:
- an illuminating unit;
- an image-capturing unit;
- and
- a control unit,
- the illuminating unit comprising:
- a light source, and
- an optical element,
- wherein the illuminating unit is configured to generate a reference pattern at an exit of said optical element;
- and
- wherein the control unit is configured to analyze an image captured by the image-capturing unit,
- wherein the control unit is configured to identify the reference pattern generated by the illuminating unit in the image captured by the image-capturing unit.
A method for monitoring for a presence of an optical element in an electronic device comprising:
- an illuminating unit;
- a control unit;
- and
- an image-capturing unit,
- the illuminating unit comprising:
- a light source, and
- the optical element;
- and
- the monitoring method comprising:
- generating a reference pattern at an exit of the optical element by the illuminating unit;
- capturing at least one image by the image-capturing unit;
- and
- analyzing, by the control unit, the captured image so as to identify the reference pattern.
