Abstract

A camera time-domain synchronization method, relating to the field of cameras, comprising the following steps of testing the delay time from startup to exposure of the camera; when the sum of the current time and the delay time is equal to the preset time, the camera is started. When the sum of the current time and the delay time is equal to the preset time, the camera is started, so that the time at which the camera starts to expose is equal to the preset time, thereby eliminating the interference of the delay time on the accurate exposure time of the camera, and avoiding the delay due to internal processing time of the camera. The difference, while affecting the accuracy of astrophotography phenomenon occurs.

Description

Technical field [0001] The present invention relates to the field of the camera, and more particularly to a time domain synchronization method of a camera. Background technique [0002] The cesium atomic clock which utilizes electromagnetic waves radiated during the two levels of electrons in the two levels of energy, and to control the calibration electronic oscillator, and then the walking of the clock. This kind of stability is very high. Currently, the best cesium atomic clock reaches 20 million years to differ in 1 second. At present, the transition frequency of the cesium atom clock is generally used as the standard of time frequency. The final adoption of the GPS satellite system is the cesium atom clock. Existing GPS modules can output a time signal in addition to the functionality capable of achieving satellite positioning, including the PPS signal based on the cesium atomic clock frequency and the calibration time based on the PPS signal output. [0003] Astronomical Ph...
