This looks like something on the Camera, and should be repaired under warranty, as the 'lens - sensor' part isn't sealed, this problem will only get worse over time, and you will have to pay to get it cleaned every time.
I won't suggest you opening it up, because for every spot you remove probably 2 new ones appear. What you could try is your local camera shop (if Sony doens't want to repair it under warranty for you (Give it a shot even if it doensn't have any warranty anymore, this shouldn't happen, EVER)) they might be adventurous enough to open it and clean it.
Just keep in mind your camera is probably 'done for' as it will cost allot of money to let it be repaired (if not done under warranty) it will probably be cheaper to get a new camera.

If it's not on the outside of the lens, then it really should be under warranty, so they'd be able to fix it for free. I'd send it in.
If they don't let you send it in, then you should consider opening it to clean it yourself. But that tends to reduce the picture quality because of lens positioning, so be extremely careful!!

As the sensor is supposed to be sealed, this is actually a pretty significant problem. It's not going to kill your pictures, but you will need to edit the blobs out if you don't like them.
If the camera is 3 years old, it won't hurt to try sending it in, but it's probably not worth repairing for more than $50-60 or so, particularly if it's just a little point and shoot.
If you decide on a new camera these would be for your pocket (Just guessing here), here's a nice inexpensive one:

A nice one that costs a bit more is the Panasonic FX35 or FX37.

The cost of cleaning dirt off a P&S's sensor would fetch one probably 5 more cameras; its not commonly done; OR its just masked off in software like Photoshop.

Is there something I can do to remove lens contamination?
I have a Sony Cyber-shot that has spots on, or inside, the lens (see photo). I have tried swabbing the front gently with melamine foam cleaning block, to no effect. Maybe the spots are inside the lens, or on the sensor? What else can I do to clean it myself (as I can't afford to send it in for repair)? 
Interesting Question?

• The link to Sony in the comment below was the most helpful thing. It saved me a lot of time, even though the agent was helpful in a limited way. I still haven't made enquiries as to whether repairs are under warranty, but I know where to ask. Thanks!

Have tried the canned air on the outside. I should have mentionend that.
Report

Because the compressed air is actually a chemical that can leave a residue. If you cover the objective of the lens carefully and use it to clean out cracks, it's one thing. If you get it on the front of the lens, it's one thing, but if you get it on the back of the lens, or on the sensor? That's not good. It will damage the sensor, and possibly the filter that is in front of it.

That's not correct. Typical canned air is not a chemical, and does not contain chemical residues. It is composed of nitrogen and other benign gases. Any appearance of residue is probably particulate matter trapped by a localized freezing process that can occur due to the temperature effect of the expanding and escaping gas absorbing heat from the local environment. It is not chemical residue from the contents of the can itself. That said, you should always use caution with canned air and apply it from a safe distance.

Checked Wikipedia, and you're right about the gasses used - it's not just nitrogen but they are said to be inert. The bottle I have in front of me still says not to use it near on a camera mirror, though. It's one of the 5 or 6 specific "do not do" things on the can.

Sounds like our advice is fairly reconciled then. Not too close fits with my caution to work at a safe distance, inert gases fits with "nitrogen and other benign gases." I will concede that the cold itself could be a problem on some surfaces if one isn't careful, possibly camera components as well... I suppose there might be a better solution than canned air but I would probably throw caution to the wind and try it anyway (personally). ;o) But that's just me...

When you look close on the lens, are they visible? It could be dust particles that are really stuck on there. It doesn't look like the sensor has a problem, based on the shape of the blotches. If it's not on the outside of the lens, then it really should be under warranty, so they'd be able to fix it for free. I'd send it in.

If I hold the lens oblique to a light source I can see a couple of old water spots visible on the front, but not in the same location as the ones that show up in photos, and not as many. I don't know what to clean the lens with aside from the melamine pad. If thre's some sort of coating I don't want to rub it off.

Try rubbing alcohol with a non-scratching towel, like one specially made for lenses. That should take off the water marks, and can dissolve some other stuff. As for the marks, you're right, it's not causing the smudges. If you don't see any dust at all, then this might not help. But it might. Sometimes (according to my optics prof, actually) dust in specially placed spots can actually create some weird blemishes.
Does the camera have a thing that closes over the lens? Try cleaning that off too. And try cleaning as close to the edges of the lens as you can get.
I'm drawing at straws here as well. But it might help.

Offthedome, that's good to know, but 1) things like isopropanol and ethanol are restricted purchases in the UK - only by prescription! and 2) the Sony agent (mentioned above) said no liquids, just dry cloth. I'm tempted to get some distilled water - as water vapour/droplets have undoubtably gotten onto the lens occasionally.

If you have a point and shoot (as it seems to be), it looks like you've got a bunch of dust on your sensor. As the sensor is supposed to be sealed, this is actually a pretty significant problem. It's not going to kill your pictures, but you will need to edit the blobs out if you don't like them.

I have been wondering if damp can get inside and mildew. But as noted above, the problems seems to be significantly something to do with memory, as the spots have faded (and may have disappeared entirely) after resetting the camera.
Report

No, the problem isn't memory. If there was a memory problem, you'd have corrupted files, which would be like this:
http://thekuipers.org/images/IMG_2279.jpg
Those are either dust spots on the sensor, dust on the lens, or, if the seal is broken could be mildew/mold/fungus, or some particulate.
The least sensitive part of the lens to image issues is actually the front glass - as you get closer to the back of the lens it will affect the image more and more.
They also won't show up as much against an active scene as opposed to a solid color.

Thanks for the examples. I am convinced that it is partly something to do with resetting the camera, and partly something that needs proper service.
The spots have faded considerably after resetting, but as new photos show, they are still visible.

I'm hoping that there might be more I can do to clean the lens front (without affecting whatever coating it might have)
I'm guessing you are from the US, so here are some number you might want to try (if not just say where you are from and I'll try and find local numbers for you)

The first questions he asked were whether the battery was fully charged and whether the camera works as normal. He then suggested resetting the camera. I did that, and the spots - which *have been* visible on images when reviewing them with the built-in display, are not visible on the subsequent photos.
Aside from that, he said use only a soft cotton cloth, no liquids, on the lens. I looked at it closely and can see small bits of lint, and what might be pollen or water. If those don't show up when I take daylight photos I may just ignore them.
