CMOS Latitude and More

In the last installment, we looked at Sony’s implementation of CMOS technology, which it calls 3ClearVid. In its implementation, each CMOS element is rotated 45 degrees. Through a complex process, three 1-megapixel ClearVid chips generate three 2-megapixel Virtual Sensors. This “interpolation” process increases each chip’s effective horizontal resolution by 175 percent while decreasing effective vertical resolution by 75 percent. The result is a measured resolution of approximately of 800 TVL/ph and 700 TVL. Although 3ClearVid’s resolution is clearly interesting, it is important not to think of resolution is ...
