Advanced Camera Settings

This tutorial gives you information about Advanced Camera Settings.

Purpose

The purpose of this tutorial is to provide detailed descriptions of various advanced settings of Camera.

Introduction

Every individual camera setting is identified by a UID to facilitate integration in the camera messaging mechanism. Each change of a parameter value causes an event notification containing the UID of the setting to be sent to all MCameraObserver2 clients of the camera. If additional information is required, clients would use the related getter function to identify the new value of the setting. Some settings may have a dependency on others. In this respect a particular setting value may disable a related supported setting.
