why the captured images not same as the seen image in running window of unreal engine

[RO-Caiyun]

Hi guys!
I'm using airsim to collect scene images in unreal engine. I 'm meeting a problem about images capturing. The captured images not same as the seen image in running window of unreal engine.I didn't change any value of camera in settings.json,(Except the width and height).The Pic as follow shows:


The top one is the seen image in running window of unreal engine,and the below one is the picture captured by recording button.As the pictures shows,the contrast of Pics have changed,It's getting too reflective.I want to get the same image as the seen image in running window by airsim recording.Does anyone know how to do it？
Thanks in advance!
