Using a light source to temporarily saturate a camera sensor of a camera connected to a computer
In some examples, a computing system may include a computing device, a display device, and a camera. The computing device includes a processor and a memory. The display device may be (1) separate from and electronically connected to the computing device or (2) integrated into the computing device. A camera may be connected to the computing device. The camera may be (1) a standalone device or (2) integrated into the display device. The camera may include a lens, a sensor, and a light source. For example, the light source may be a light emitting diode (LED) or an organic LED (OLED). Providing power to the light source causes the light source to emit an amount of light sufficient to saturate the imaging sensor such that if the camera is hijacked by a third party, the image data from the saturated sensor is distorted and unusable.

13. The computing device of claim 10 , wherein:
when the OLED film is being provided the power, touching the OLED film causes a capacitance sensing property of the OLED film to stop providing the power, causing the OLED film to stop emitting the light; and
when the OLED film is not being provided the power, touching the OLED film causes the capacitance sensing property of the OLED film to provide the power, causing the OLED film to emit the light.
14. The computing device of claim 10 , wherein:

the OLED film is either:
placed over the lens, or
