A method for reducing image noise in computer vision includes identifying a pattern of periods during which visible light is not emitted by the pixels; identifying a first black period during which a first group of lines of the pixels does not emit visible light; capturing, with an image sensor installed behind the display, a first image that longitudinally spans only the first group of lines of the pixels; and synchronizing the capturing of the first image with the first black period.

Method and device for reducing image noise

An electronic privacy apparatus, for selectively blocking transmission of data from a camera, includes a camera, a first processor, a switch, and a second processor. The first processor is connected to the camera and receives image data from the camera. The switch is connected to the first processor. The second processor is configured to execute an operating system. The first processor implements a transmission state where the first processor transmits the image data to the second processor. The first processor also implements a privacy state where the first processor transmits blank data to the second processor. Based on user input, the switch selects either the transmission state or the privacy state and transmits a signal to the first processor indicating the user input.
