1. A time-lapse photographic device, comprising:
a camera module;
a drive module, connected to the camera module and configured to drive the camera module to rotate;
an environment detection module, detecting an external environment of the time-lapse photographic device to generate an environment detection signal;
a control unit, electrically connected to the camera module, the drive module, and the environment detection module, wherein the control unit generates, according to a shooting stop parameter, a plurality of intermittent drive signals to control the drive module, and controls the camera module to shoot at intervals of the drive signals, and the control unit controls operation of at least one of the camera module and the drive module according to the environment detection signal; and
an angle detection module, electrically connected to the control unit and configured to detect a rotation angle of the camera module to generate an angle detection signal,
wherein the control unit adjusts the intervals of the drive signals according to the environment detection signal,
wherein the control unit controls the drive module to correct the rotation angle of the camera module according to the angle detection signal, and
wherein the control unit adjusts lengths of the intervals of the drive signals according to the angle detection signal.
