ThankS although I know this comand !~

perhaps my thoughts was strange,
But if U think :
if U don't want change the whole image brightness but just only want change a local of the image brightness !!!

In this case, you cannot use a simple command to realize it

My thoughts was pixel-to-pixel rewrite a image ,
Although it looks like the corpImage , but it could change any pixels color !

snibgo tould : use a compiled language. i think he is right ! hehe
i just don't know how to use in PHP code ??

If you must do processing pixel-by-pixel, use a compiled language. Thanks snibgo :) I have a little understand but my programming technology is little superficial hehe so how should I do in the PHP procedure , is use of PHP function to call ImagickMagick command line In order to realize this goal ?...

i use imagick function point in PHP write a code to operate pixel to change image brightness. but the processing speed surprisingly slow ! Need several minutes to estimate ! Just like the browser collapsed ! but if use imagick to resize image or add Text on image ... and so on these common functions...
