should have a test image with three white spots noted. I will
appreciate your evaluation.

Almost certainly very small flecks of dust (or perhaps smoke) near the
lens, which get illuminated by the flash, and appear as out-of-focus
blobs.

The visibility will be dependant on the axial distance between the flash
and the lens, and the depth of field. With a point and shoot camera, the
very small lens focal length means that the depth of field is very great.
The small distance between the flash and the lens means that the particles
are very brightly illuminated. Thus the flecks, rather than just creating
a general hazy atmosphere, actually appear as out-of-focus blobs.
