This document introduces you to the Histogram API of the Ecam component.
This document shows you the detailed description of tutorial and how to work with it.
A Histogram is a graph that gives the information about the exposure of the captured frame. It gives details about the distribution of light on a picture.

You can display the histogram information directly on a viewfinder or analyze it using any analysis software.
