Abstract
An electronic device may include a display and control circuitry that operates the display. The control circuitry may be configured to daltonize input images to produce daltonized output images that allow a user with color vision deficiency to see a range of detail that the user would otherwise miss. The daltonization algorithm may be specific to the type and severity of color vision deficiency that the user has. The control circuitry may conduct a color vision assessment using the display. The color vision assessment may include a sequence of test images that are each displayed for a predetermined period of time before moving to the next test image in the sequence. Each test image may include a color patch on a neutral background. A predetermined number of severity levels for each type of color vision deficiency may be tested during the color vision assessment.
