This document introduces you to the Histogram API of the Ecam component.

-
Purpose

This document shows you the detailed description -of tutorial and how to work with it.

-
Introduction

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.

The histogram explains -which portions of the frame are over-exposed or under-exposed and helps you -to adjust the captured frame accordingly.

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

Setup and Configuration Requirements

The following examples -assume a camera object exists.

The code in this tutorial -can be found in …\os\mm\imagingandcamerafws\cameraunittest\src\ECamUnitTestPlugin\extended_functionality.cpp.

-
Using Histogram

The histograms can be created -for:

    -
  • still image

  • -
  • video frames

  • -
  • both client and direct -viewfinders.
