Can any one help me in understanding the difference between high contrast and saturated pixel in image

Hi
Can any one help me in understanding the difference between high contrast and saturated/glare pixel…

Thank u…

Contrast is the difference in brightness that makes objects distinguishable in an image. It is related to the range of pixel values. A saturated pixel is one that has reached its maximum value.

Here is a wiki entry that describes saturation and offset: https://imagej.net/Detect_Information_Loss
