Abstract

A method for switching a high dynamic range mode, an electronic device, and a storage medium are provided, and relate to the field of terminal technologies. The method is applied to an electronic device supporting a lateral overflow integration capacitor LOFIC high dynamic range HDR mode and a dual analog gain DAG HDR mode, and includes: starting a camera running program; obtaining an illumination intensity of an environment in which the electronic device is located; and enabling the LOFIC HDR mode. According to this solution, when the illumination intensity decreases, instead of remaining the LOFIC HDR mode, the HDR mode is switched to the DAG HDR mode. A feature that both a long frame and a short frame in the DAG HDR mode use a same conversion gain is used. This can relieve a signal-to-noise ratio dip in a transition region of a bright part and a dark part, and improve photographing experience of a user.
