Image recognition method, electronic device, and storage medium

An electronic device comprising:

• an infrared light;
• a camera;
• a storage device;
• at least one processor;
• and
• the storage device storing one or more programs that, when executed by the at least one processor, cause the at least one processor to:
• turn on the infrared light;
• in response to a determination that an ambient light intensity of an object to be recognized is changed in a first direction, control an intensity of infrared light emitted by the infrared light to change in the first direction, control an exposure parameter of the camera to change in a second direction, maintain a grayscale of an object face in an object image captured by the camera within a first grayscale range, and maintain an average background grayscale of the object image within a second grayscale range, wherein the second direction is opposite to the first direction, and grayscales of the second grayscale range beingless than a lower limit of a preset grayscale threshold recognizable by human eyes;
• and
• recognize the object to be recognized from the object image.

A non-transitory storage medium having instructions stored thereon, when the instructions are executed by a processor of an electronic device, the electronic device comprises an infrared light and a camera, the processor is caused to perform an image recognition method, wherein the image recognition method comprises:

• turning on an infrared light;
• in response to a determination that an ambient light intensity of an object to be recognized is changed in a first direction, controlling an intensity of infrared light emitted by the infrared light to change in the first direction, controlling an exposure parameter of the camera to change in a second direction, maintaining a grayscale of an object face in an object image captured by the camera within a first grayscale range, and maintaining an average background grayscale of the object image within a second grayscale range, wherein the second direction is opposite to the first direction, and grayscales of the second grayscale range beingless than a lower limit of a preset grayscale threshold recognizable by human eyes;
• and
• recognizing the object to be recognized from the object image.
