Differences of image values between J2SE and J2ME

[logiclips]

Hi,

On my mobile device, I take a snapshot with my J2ME application and
store this image as png. Then, I send it to my J2SE Application on my
PC. Now I look at the RGB values of the image on my PC and on my mobile
device (the images are equal).
I have recognized that the values are not equal! The differences are
between 0 to 3 value steps in each color channel.
Can someone explain me that? How can I make them equal?

In J2ME I'm using the javax.microedition.lcdui.Image class, in J2SE I
use java.awt.Image in combination with java.awt.image.BufferedImage.


Thanks,

Peter Vermeer

this could be cos of the the color system difference in the 2
platforms.
windows has a 256bit or 16 bit color which you can set in display
properties.
if these 2 setting are incompatible you will see a difference.

Hi,

Do you think that the different display systems are the reason? I don't
think so, because the images are exactly the same. I look at the RGB
values in exactly the same images on both platforms. It's not a matter
of how I conceive them. The physical values are different, e.g. the
first pixel of the image has the values 165 158 148 on my mobile device
and 164 158 151 on PC.
