What is photo distortion?
What is photo distortion? I believe that many inexperienced people are at a loss about this, so this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.
Photo distortion refers to the decline of image quality caused by the loss of image information in the process of image storage; distortion, also known as "distortion", refers to the deviation of the signal compared with the original signal or standard in the process of transmission. In an ideal amplifier, the output waveform should be exactly the same as the input waveform except amplification.
Distortion is the loss of image information in the process of transfer, resulting in the decline of image quality.
Because GIF pictures store a single raster image data or multiple raster image data in 8-bit colors or 256 colors. GIF compression is LZW compression with a compression ratio of about 3:1. GIF supports only 256-tone swatches, so detailed pictures and realistic photographic images lose color information and appear to be toned. This is the reason for the distortion of the picture.

Distortion, also known as distortion, refers to the deviation of the signal compared with the original signal or standard in the process of transmission. In an ideal amplifier, the output waveform should be exactly the same as the input waveform except amplification, but in fact, the output waveform cannot be exactly the same as the input waveform. This phenomenon is called distortion.
