This invention relates to the field of smart wearable device technology, and mainly discloses a smart ring and its usage method. The smart ring includes a ring body, an environmental sensing module, and an image acquisition module. The ring body is configured to be worn on a user's finger. The environmental sensing module is located in the ring body and includes a distance measurement unit and a light sensing unit. The distance measurement unit is configured to measure the distance between the target being photographed and the ring body and pre-calculate focal length parameters. The light sensing unit is configured to measure the ambient light intensity and pre-calculate exposure parameters. The image acquisition module is located in the ring body and is configured to acquire an image of the target being photographed based on the pre-calculated focal length and exposure parameters. This invention aims to solve the problems of high power consumption and short battery life of existing smart rings due to the image acquisition module.
