It's what you sell when you don't have the real > thing. Actually as I understand it there are more actual pixels than effective pixels! (Effective pixels here are as in the now accepted sense not the original marketing of the Fuji S1) You take four actual pixels two sensitive to green, one sensitive to red and one sensitive to blue, to a simple photographer (particularly the flat earthers!) that would make one usable 24 or more bit RGB pixel. That would throw away some useful data so then you calculate the colour and density of each of those actual physical pixels by looking at the four adjoining pixels. The pixels on the edges of the CCD (or presumably CMOS?) don�t have four adjoining pixels for these calculations so are only used for their contribution as 'adjoining pixels' hence the total 'effective pixels' are less than the total actual pixels.
So it is worth noting that the pixels in the file are not the pixels in the CCD unless you have a high end three pass back, Fuji just stretch them a little further than the others Paul Lawrence --- Outgoing mail is certified Virus Free.
