Displaying image data based on ambient light

The invention relates to displaying image data based on ambient light. Various implementations disclosed herein include devices, systems, and methods for displaying image data based on ambient light. In some implementations, an apparatus includes an image sensor, an environmental sensor, a display, a non-transitory memory, and one or more processors. In some implementations, a method includes capturing, via an image sensor, first image data corresponding to a body part of a user of a device. In some implementations, the method includes detecting, via an environmental sensor, environmental data indicative of a current ambient light condition of a physical environment surrounding the device. In some implementations, the method includes generating second image data by modifying the first image data based on a function of a current ambient light condition and a threshold ambient light condition detected during enrollment. In some implementations, the method includes displaying second image data on the display. 本公
