Various implementations disclosed herein include devices, systems, and methods for displaying image data based on ambient light. In some implementations, a device 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 the image sensor, first image data that corresponds to a body part of a user of the device. In some implementations, the method includes detecting, via the environmental sensor, environmental data that indicates 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 the current ambient light condition and a threshold ambient light condition detected during enrollment. In some implementations, the method includes displaying the second image data on the display.
