Gamma value is an important parameter in image processing, which mainly affects the brightness and contrast of the image. Gamma value does not directly cause the image to be "distorted", but it can significantly change the visual appearance of the image, especially the details of the bright and dark parts.
Gamma value is a correction coefficient used to describe the nonlinear relationship between the input brightness value (such as a display, camera or scanner) and the output brightness value. When the gamma value is greater than 1, the high brightness part (bright part) of the image will become brighter, and the low brightness part (dark part) will become darker, which will increase the contrast of the image, but may cause the details of the dark part to be lost. On the contrary, when the gamma value is less than 1, the dark part of the image will become brighter, the bright part will become darker, and the contrast will be reduced, but the details of the dark part may be easier to see.
Therefore, it is not accurate to say that the higher the gamma value, the more distorted the image. The choice of gamma value should be determined according to the specific application scenario and the visual effect to be achieved. In some cases, appropriately increasing the gamma value can enhance the contrast and layering of the image, making the image look more vivid; in other cases, reducing the gamma value may be more conducive to showing the details and layers of the image.
In short, the Gamma value is a tool for adjusting the brightness and contrast of an image, not the cause of image distortion. Reasonable use of the Gamma value can improve the visual effect of the image, but excessive adjustment may cause the image to appear unnatural or lose details.
