There is a bright circle between the digital camera screen and the photos taken.

According to what you said, it seems that the photosensitive elements of the camera (some CCD, some CMOS) were burned out by the strong light of the sun, because the role of the lens in the lens is to collect the scene of Guangyu on a relatively small photosensitive element, which is focusing in a broad sense. We have all played with magnifying glasses and lit wood or paper by focusing in the sun. When you focus the lens on the sun, the strong light of the sun will burn out the photosensitive element. The subsequent solution is to replace the photosensitive element.
