All Models – SmallHD – Technical – False Color

PROBLEM

I’m using identical exposure assist (false color) settings on a 1703 and a 702, but looking at the same scene they produce different results.

SOLUTION

From R&D:

"In order to render false color on an image, calculations must be performed on the pixel data. The accuracy of the result is dependent upon how much precision is kept throughout the calculation process. In this case, the 1703 product keeps a greater amount of precision than the 702 Bright product, resulting in a more accurate false color rendering.

For reference - products with the most accurate false color calculations are the UltraBright series (503UB, 703UB) and all Production Monitors (1300 series, 1700 series). While products with less precision do not experience a major loss of accuracy (on the order of ~1%), a noticeable difference in false color rendering can be observed when comparing side-by-side with a higher precision product."

This largely boils down to the difference between 10 bit colors versus 8 bit colors. Ten bits will be more precise, and in something like false color where the bands are narrow, even a slight difference can move a number from one color into another. Overall, both monitors should keep you within recommended exposure levels. If you're trying to be very precise about a very specific part of a scene, though, the 1703 can take advantage of its greater color accuracy.
