Embodiment Construction
[0034] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and examples, so as to fully understand and implement the process of how to apply technical means to solve technical problems and achieve technical effects in the present invention.
[0035] In the process of flash recapture, it is necessary to judge the occurrence of flash, and then perform flash recapture. The system judges whether there is a flash by detecting the change of the magnitude of the correlation value R(m).
[0036] (1) Flash judgment process
[0037] Under normal circumstances, the magnitude of the correlation result R(m) at the mth correlation is relatively large. When the signal flickers, the magnitude of the correlation value R(m) drops rapidly, which is basically white noise. Therefore, whether there is a flicker can be judged by detecting the change of the magnitude of the correlation value R(m).
[0038] The specific method ...
