Abstract
An information handling system camera has physical security with a shutter that blocks the camera lens and a block member that separately blocks an infrared sensor. A ring rotates around the lens and engages with leaf members so that rotation of the ring opens and closes the leaf members. The block member extends inward from the ring towards the lens align with and block the infrared sensor when the leaf members block the lens and to expose the infrared sensor when the leaf members expose the lens.
Claims19
An information handling system comprising:
- a housing;
- a processor disposed in the housing and operable to execute instructions that process information;
- a memory disposed in the housing and interfaced with the processor, the memory operable to store the instructions and information;
- and
- a camera interfaced with the processor, the camera having a lens, an image sensor, and infrared sensor and a shutter, the lens directing light to the image sensor, the image sensor capturing visual images, the shutter having a ring configured to rotate around the lens, the ring having an opening aligned with the lens, the ring coupled with a leaf that blocks the lens when the ring rotates in a first direction and exposes the lens when the ring rotates in a second direction, the ring having an extension directed inward towards the lens and into the ring opening, the extension aligned to block the infrared sensor when the ring rotates in the first direction and expose the infrared sensor when the ring rotates in the second direction.
A method for blocking an information handling system camera field of view, the method comprising:
- rotating a ring coupled around a lens of the camera in a first direction from a first position to a second position, the ring having an opening aligned with the lens;
- translating the rotating to move first and second leaf members over the lens to block light from entering the lens;
- and
- blocking an infrared sensor with a blocking member directly coupled to the ring and extending into the opening that rotates over the infrared sensor in the second position.
A camera comprising:
- a lens;
- an image sensor;
- an infrared sensor;
- a shutter, the lens directing light to the image sensor, the image sensor capturing visual images, the shutter having a ring configured to rotate around the lens, the ring coupled with a leaf member that blocks the lens when the ring rotates in a first direction and exposes the lens when the ring rotates in a second direction, the ring having an extension directed inward towards the lens and aligned to block the infrared sensor when the ring rotates in the first direction and expose the infrared sensor when the ring rotates in the second direction;
- a pin extending from the leaf member into a slot of the ring;
- and
- a pivot fixed relative to the lens and rotationally coupled to the leaf;
- wherein the slot radius relative to the lens decreases at the pin when the ring rotates in the first direction and increases at the pin when the ring rotates in the second direction.
