Deformation and discoloration like jelly in production and life.

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. Of course, all the actions are completed in a very short time, which generally will not affect the shooting. But if the object being photographed moves or vibrates rapidly relative to the camera. When shooting with a rolling shutter, the progressive scanning speed is not enough, and the shooting result may be "tilted", "shaken" or "partially exposed". This phenomenon of rolling shutter shooting is defined as jelly effect.

The effects of jelly are as follows: 1. As for the jelly effect of the camera, the global shutter is realized by simultaneously exposing the whole scene.

All pixels collect light at the same time and expose at the same time. That is, at the beginning of exposure, the sensor begins to collect light; At the end of exposure, the light collection circuit is cut off. The sensor values are then read out as photographs. CCD is the working principle of Globalshutter. If the object moves at a high speed relative to the camera. If you shoot with Globalshutter, the exposure time will be too long and the photos will be burnt. However, when shooting with Rollingshutter, the progressive scanning speed is not enough, and the shooting result may be "tilted", "shaken" or "partially exposed". This phenomenon of Rollingshutter shooting is defined as jelly effect.

2. Regarding the jelly effect in handmade soap, the saponification reaction of soap is still going on after the soap is poured into the mold. When the temperature of the soap rises, a large transparent circle will be formed in the middle of the soap, which will slowly spread outward. The whole soap is translucent like jelly. Generally speaking, this is a reasonable phenomenon in the saponification process. If it is cold-made soap, there are usually many deep layers and shallow layers from the inside out due to the difference between the external temperature and the internal temperature when pouring, and the color of the outermost layer is the lightest, but the jelly effect is not artificially controllable. Therefore, only a few handmade soaps in the same batch have this phenomenon. One day after the soap body is cut, these obvious layers will gradually fade away and disappear.
