The invention relates to an image processing method and device, an electronic device, and a computer readable storage medium. The image processing method includes the steps: detecting the temperatureof a light source emitter, and when a difference between the current temperature of the light source emitter and the initial temperature exceeds a threshold, acquiring a corresponding target parameteraccording to the current temperature of the light source emitter, and acquiring a target preview image according to the target parameter. As the image processing method can obtain the corresponding parameter to collect images according to the temperature of the light source emitter, the image processing method can reduce deviation of the collected images.
