ICC profiles are (unfortunately) not typically gamma tables. They tend<br>
|
|
to be on the order of 300K files. I think that applying ICC correction<br>
|
|
is out of the realm for the scanner driver, although it may choose to<br>
|
|
arrange for profiles to be associated with the the image.<br>
|
|
<p>
|
|
Hardware manufacturers are typically responsible for producing a profile<br>
|
|
for their hardware, though that is not required, not all do, some get third<br>
|
|
parties to do it, and there is nothing preventing the random individual<br>
|
|
making a profile of his/her own. That implies that the driver need not<br>
|
|
even *carry* the profile.<br>
|
|
<p>
|
|
Typically, the display tool applies the profiles for the scanner and<br>
|
|
the display device to the image at the time the image is rendered. The<br>
|
|
user may even select the profiles to be applied, depending on the tool.<br>
|
|
So this is, and should remain, entirely a front-end issue.<br>
