Jelly effect refers to the deformation and discoloration similar to jelly in production and life. The formation of jelly is determined by the characteristics of the camera itself. Cameras using CMOS sensors mostly use rolling shutters, which are realized by line-by-line exposure of image sensors. At the beginning of exposure, the image sensor scans the exposure line by line until all pixels are exposed.
