Abstract
An illustrative display device preserves scotopic vision for a user. The display device includes a display configured to present image content, a memory storing instructions and operating parameters, and a processor coupled to the memory and configured to execute the instructions. The operating parameters may include a color parameter and an additional parameter, such that the execution of the instructions allows the processor to switch the display device between: 1) a normal operating mode in which the color parameter is set to cause the display to present the image content in full color and the additional parameter is set to a first setting, and 2) a scotopic preservation mode in which the color parameter is set to cause the display to present the image content in red color and the additional parameter is set to a second setting different from the first setting. Corresponding methods and devices are also disclosed.
