Image compression works by reducing the amount of visible

information. So whereas the original picture might be able to display 65

million colors, since the eye can not differentiate between anywhere near this

number of colors the software is going through and removing colors that are not

needed. The actual complexity of the algorithms is far more complex than that,

and beyond the scope of this response. But the threshold (assuming I understand

your context correctly) has to do with how the algorithm decides what

information to throw away and what information to keep, and thus will affect

the resulting quality and size of the image after compressions.
