The invention relates to a countdown photo-taking prompting method and device. The method comprises the following steps: acquiring a photo-taking distance between intelligent equipment and a user of whom a photo is to be taken; judging whether the photo-taking distance is greater than a preset distance or not; and if the photo-taking distance is greater than the preset distance, performing countdown photo-taking prompting through a flashlight by the intelligent equipment. Through the scheme, the countdown photo-taking prompting effect is enhanced.
