Abstract

A self-image capturing method includes a user activating a capturing device, controlling a light detecting device to detect ambient light intensity around an electronic device, determining whether the light intensity detected by the light detecting device is less than a predetermined value, activating the infrared capturing device when determining that the light intensity detected by the light detecting device is less than the predetermined value, controlling the capturing device to capture a selfie image of the user in response to an operation from the user, controlling the infrared capturing device to capture an infrared selfie image, and synthesizing the two captured images into a single selfie image.
