SBC looks really weird with bright white or red covers, then it gets
all blocky and pixelated.

You are not picky. I noticed the bug during the first two minutes of
using the Controller. I was shocked -- *SHOCKED!!*-- ;) to see it has
been around since 2008 and still not fixed.
Baah there are 9 year old bugs in the system ;) targeted for future,
Since the Controller uses the same display as the Radio, shouldn't that
effect be visible there, too?

Different cpu and probably other system differences on the hardware
level, I can not compare have no radio yet.
But if they solved it on the radio and NOT backported it to

Hi
I must agree, that the display quality of album art leaves much to be
desired.
Overall the display quality of the user interface looks good, the
letters are good and sharp, but this is not the case with album art,
which has too many artifacts.

Any news on this matter, the bugreport also is quiet...

BUMP
I see that there has been no movement in the bug report 7462. Is there
any news on this issue ? I have the same problem with a lot of my
artworks.

Any headway on this issue? Almost all of my album artwork that has any
significant area of white or extremely light areas blending into darker
show these unattractive artifacts. I do hope it can be corrected.

Looks familiar. I've seen this kind of 'effect' too, I blamed it on the
source material, never investigated.

Thanks for the pictures. I'm playing with it in photoshop and put
your image up on the Controller screen.
I see a couple of things:
1. The color banding effects are strong with this particular image.
I was able to reproduce the color pattern closely in photoshop with 32
levels of

is better from the natural angle when holding the device in your hand,
slightly _below_ perpendicular. I was able to

So the takeaway is that we can do better by doing a proper dither on the

Great! I believe this will take care of the problem. Please use
Floyd-Steinberg dithering (or an equally good method).
BTW, what
According to the specifications, the Controller has a 256K color display
(should that really be 256,000 or 256?), yet the quality of displayed
colors is nowhere near what it could be on a 256 color screen. The
display quality looks like the image is quantized to a fixed set of
colors without
The SBC display is certainly capable of very good quality images, just
take a look at the flickr screensaver or some of the background images
for examples. I personally don't think the issue point out is due to
colour space reduction (24bit vs ~18bit really isn't much of a visible
difference) but
Good point. However, colors would not suffer from size reduction even
when a very crude pixel dropping method is used. I just tried resizing
to 150x150 without interpolation (=pixel dropping in PMView) and the
only obvious defect is jagged edges. Colors are 100% ok.
The errors I see in the SBC
The SBC display is actually 16-bit.
The images are converted to 24-bit GD format, which is essentially raw,
then sent to the SBC and displayed as 16-bit (5-6-5). There is some
banding, but I don't think that it's as bad as the example you posted.
The SBC doesn't do any dithering, but it

The problem I'm seeing is not banding. I know what banding is, and the
SBC does not display the image nearly as well as a 5-6-5 display
would.

Thanks. I will do that. Obviously the software is doing some really
bad
things with the image before it's sent to the SBC.
Now
Thanks. Here is the original image (artwork.jpg) that SqueezeCenter
uses. I've also added another artwork (renamed to artwork2.jpg) that
shows the same type of problem. I can easily find more examples, but
I'm sure these two are enough.
Please see if you can repeat the problem with these images.
I was going to open up a bug report, however, what category should I
open it under? There is no specific category for the SBC...
Here are two images that clearly show the problem in the SBC. (I can
easily find more examples if needed).
Can you repeat the problem?

Jive Software, UI component.
the Controller was formerly known as Jive.

I've had similar experiences with album covers with similar backgrounds.
