Pixel Density of Fuji's CCDs

[sjong47]

All the following calculated based on 4:3 aspect ratio using pyth's theorem


6.3 MP 1/1.6-inch diagonal ccd: Area = 0.166 sq in : Density = 38 MP per sq in

9 MP 1/1.7-inch diagonal ccd: Area = 0.1875 sq in : Density = 48 MP per sq in

11 MP 2/3-inch diagonal ccd: Area = 0.2133 sq in : Density = 52 MP per sq in

12 MP 22mmx15mm ccd on SLR: Area converted = 0.55 sq in : Density = 22 MP per sq in
If you count it as 6MP (which it really is)... Density = 11 MP per sq in !!!


Goes to show that other than the SLR ccds, the older 6.3 MP ccds would still be better choice than the newer 9MP and 11MP consumer/prosumer camera ccds...


Digress using Sony's 35mm full frame 24MP ccd
Area after conversion = 1.3 sq in : Density = 18 MP per sq in... Interesting!

sad but true... most consumer who buy those PnS do not know about such technical details and are always sway towards more MP = better and newer...

You think only PnS owner? This also apply to DSLR owner. Like Canon is upgrading their entry level DSLR to 12MP, Sony to 14MP. And some people are looking at switching to Sony A350 because of the 14MP. Since Sony started thw pixel war with their 14MP cropped sensor and 24MP full frame sensor, I won't be surprise that within 3 years, the cropped sensor will have 16-20MP as "normal" and 25-30MP for full frame sensor.

I predict the Megapixel war will only end when it reach 40 MegaPixel when either no more improvement in optical performance or the diffraction effect start to negate any further improvement in detail.
