What is the jelly effect?

The main meaning of the jelly effect:

Refers to the deformation and color changes that occur like jelly in production and life.

Detailed explanation:

The formation of jelly is determined by the characteristics of the camera itself. Most cameras using CMOS sensors use a rolling shutter, which is achieved by line-by-line exposure of the image sensor. of.

At the beginning of exposure, the image sensor scans line by line and exposes line by line until all pixels are exposed. Of course, all actions are completed in a very short time and generally will not affect the shooting.

But if the object being photographed moves at high speed or vibrates rapidly relative to the camera. When shooting with the rolling shutter method, the progressive scan speed is not enough, and the shooting results may appear "tilted", "wobbly" or "partially exposed". This rolling shutter shooting phenomenon is defined as the jelly effect.

Extended information:

The main jelly effects are as follows.

1. About the jelly effect of the camera

Global shutter and Rolling shutter.

2. About the jelly effect in handmade soap

After the soap liquid is poured into the mold, the saponification reaction of the soap liquid is still continuing. As the temperature of the soap liquid increases, there will be It forms a large transparent circle and slowly spreads outward. The whole soap feels like jelly and is translucent.

Methods to avoid the jelly effect:

1. Change the shutter speed

When using a high-speed shutter, the scenery will be clear, and movement will be easier to see, and Just make the jelly effect more significant. Therefore, using a slow shutter speed, or in other words, making the exposure time much longer than the pixel reading time, the motion blur of the object will be stronger, the feeling of deformation will be reduced, and the jelly phenomenon will not easily occur.

2. Reduce the vibration of the drone itself

The aircraft frame, motor, gimbal, camera and some inconspicuous small parts may be the source of vibration. Each aircraft and different types of gimbals and cameras will have different vibrations. Try to reduce the vibration of the aircraft as much as possible.
