Why is my Fuji bridge camera showing more bright colored pixels over time?

My Fuji FinePix S8100 is showing isolated green and blue bright pixels in photos, and it seems to be getting worse over time. The spots are visible in normal photos, in a shot of white paper, and in a dark-room shot. The lens is clean, and the bright pixels do not seem to stay in exactly the same place from image to image. What is the most likely cause, and is this something I can fix myself?

It looks like these pixels do not always appear in the same location (comparing the rose and paper picture, for example). Therefore we can rule out faulty dead pixels in the sensor. As these are isolated bright pixels it's also unlikely that they are caused by the lens/optics.
My guess is that these artifacts come from the image processing software of the camera. If your camera supports storing images in RAW format, try if these bright pixels appear in RAW images as well.
It also seems that Finepix S8100 is already quite old and it has a small 10MP sensor, so it could just be that the image quality is not great by contemporary standards (compared to good phone cameras for example).
You can, of course, take the camera to a Fuji service location for a better assessment.

Because the bright pixels do not appear in the exact same locations from shot to shot, they are unlikely to be simple stuck/dead sensor pixels. Isolated colored dots like this are also unlikely to be caused by the lens.
A more likely explanation is image-processing noise or artifacts from the camera’s internal processing, especially given that the FinePix S8100 is an older bridge camera with a small sensor. As cameras age, noise performance can become more noticeable, and older processing can look worse by modern standards.
A good test is to shoot RAW, if your camera supports it, and compare the RAW file with the JPEG. If the dots are only in JPEGs, the issue is probably in-camera processing. If they are also in RAW, the sensor/electronics may be the source.
There usually isn’t a practical DIY fix for this beyond checking settings, using lower ISO where possible, and testing RAW vs JPEG. If the problem is severe, a Fuji service center would be the best place to have it assessed.
