SMALL FORM FACTOR ACTIVE ILLUMINATION PRIVACY SHUTTER - A simplified explanation of the abstract
This abstract first appeared for US patent application 17875951 titled 'SMALL FORM FACTOR ACTIVE ILLUMINATION PRIVACY SHUTTER
Simplified Explanation
An information handling system camera captures visual images using a lens and an image sensor. The camera includes an active illumination privacy shutter that prevents the image sensor from capturing visual images by introducing illumination between the lens and image sensor. This is achieved by using a red light emitting diode (LED) that appears as a red dot at the lens when viewed from the front of the camera. The illumination is directed towards a light diffuser, such as a sheet of acrylic, which is positioned between the lens and image sensor when the camera is in privacy mode.
- The camera has an active illumination privacy shutter that disables the image sensor from capturing visual images.
- The privacy shutter introduces illumination between the lens and image sensor.
- A red LED is used to provide the illumination, which is visible as a red dot at the lens.
- The illumination is directed towards a light diffuser, such as a sheet of acrylic.
- The light diffuser extends between the lens and image sensor when the camera is in privacy mode.
Potential Applications:
- Privacy protection in information handling system cameras.
- Preventing unauthorized visual image capture.
- Enhancing privacy in sensitive environments.
Problems Solved:
- Protects against unauthorized visual image capture.
- Provides a visual indication of privacy mode.
- Enhances privacy in situations where visual image capture is not desired.
Benefits:
- Improved privacy and security.
- Easy identification of privacy mode.
- Versatile and adaptable to different information handling system cameras.
Original Abstract Submitted
An information handling system camera captures visual images of light directed by a lens towards an image sensor. The camera has an active illumination privacy shutter that disables the image sensor from capturing visual images by introducing illumination between the lens and image sensor, such as with a red light emitting diode that is seen as a red dot at the lens when viewed from in front of the camera. In one embodiment, the illumination is directed towards a light diffuser, such as a sheet of acrylic, that extends between the lens and image sensor when the camera is commanded to a privacy mode.
