The application discloses a shooting delay calculation method which includes the following steps: acquiring n frames of images of a video sequence shot by an image acquisition module and recording theacquisition time of each frame of image, wherein n>=2; sending a preset configuration instruction to the image acquisition module at a first time, wherein the configuration instruction is used to modify the shooting parameters of the image acquisition module; determining a target image in the n frames of image, wherein the target image is a first frame of image shot based on the modified shootingparameters; determining the acquisition time of the target image as a second time; and calculating the time interval between the first time and the second time, and recording the time interval as theshooting delay of the image acquisition module. According to the application, the shooting parameters of the image acquisition module are modified, and the time when the shooting parameters are modified is recorded as a first time; then, a shot image is acquired, the time when a first frame of image is shot after modification of the shooting parameters is acquired as a second time; and the shooting delay is obtained according to the time difference between the first time and the second time.
