How to setup the Brightness / Saturation / Contrast values of the camera image in C#

In this guide you can find detailed information on how to set preferences like brightness, contrast and saturation of your IP camera. To implement this example, you need to have Ozeki Camera SDK installed, and a reference to OzekiSDK.dll should be added to your Visual Studio project.

How to set the preferences (brightness, contrast, saturation) of an IP camera device using C#?

Windows Form WPF  

Windows forms version

To establish the connection properly between your application and an IP camera you should apply the same code snippet what you have used in the example (How to connect to an IP camera device using C#?). Important: you should study this article in order to find out how to setup your Windows Forms Application correctly.

Getting started

To get started it is recomended to Download and Install the latest version of Ozeki Camera SDK. After installation you can find the example code discussed in this page with full source code in the following location on your harddisk:

Download Ozeki Camera SDK: https://camera-sdk.com/p_6513-download-onvif-ozeki-camera-sdk-for-c-sharp.html
Windows forms version: C:\Program Files\Ozeki\Ozeki SDK\examples.zip\Examples\Other\
Camera_Viewer_Brightness_WF\Camera_Viewer_Brightness_WF.sln

To compile this example you will need Microsoft Visual Studio installed on your computer.

To find more about the previously used functions included here as well, please, visit this tutorial

The additional statements and methods of this example are the following:

TrackBarBrightness_Scroll(),
TrackBarContrast_Scroll(),
TrackBarSaturation_Scroll()
These three new methods provide the additional functionality of this example. These methods are listening to their own scroll bar GUI elements and whenever the scroll bars are being modified the appropiate property of the camera image is also changing.

_camera.CameraStateChanged += Camera_CameraStateChanged;
InvokeGUI()
These methods and event serve the functionality to load in and display on the GUI elements the IP camera's current preferences as soon as the streaming process has been started. This is a really short and elegant solution for C# cross-thread operations. The next example will demonstrate this technique as well.

Code 2 - GUI example in C#


WPF version

To establish the connection properly between your application and an IP camera you should apply the same code snippet what you have used in the example (How to connect to an IP camera device using C#?). Important: you should study this article in order to find out how to setup your WPF Application correctly.

Getting started

To get started it is recomended to Download and Install the latest version of Ozeki Camera SDK. After installation you can find the example code discussed in this page with full source code in the following location on your harddisk:

Download Ozeki Camera SDK: https://camera-sdk.com/p_6513-download-onvif-ozeki-camera-sdk-for-c-sharp.html
WPF version: C:\Program Files\Ozeki\Ozeki SDK\examples.zip\Examples\Other\
Camera_Viewer_Brightness_WPF\Camera_Viewer_Brightness_WPF.sln

To compile this example you will need Microsoft Visual Studio installed on your computer.

To find more about the previously used functions included here as well, please, visit this tutorial

The additional statements and methods of this example are the following:

First, it is recommended to subscribe the camera's CameraStateChanged event before start the camera to query the camera's different image properties like minimum, maximum and current value when the camera is in streaming state:

_camera.CameraStateChanged += Camera_CameraStateChanged;

TrackBarBrightness.Minimum = (int)_camera.ImagingSettings.BrightnessInterval.Min;
TrackBarBrightness.Maximum = (int)_camera.ImagingSettings.BrightnessInterval.Max;
TrackBarBrightness.Value = (int)_camera.ImagingSettings.Brightness;

With the three trackbars you are able to set the camera's different image attributes and refresh it by the following methods:
_camera.ImagingSettings.SetAttributes(new CameraImaging { Brightness =
Convert.ToSingle(TrackBarBrightness.Value) });
_camera.ImagingSettings.RefreshProperties();

InvokeGUI() method serve the functionality to load in and display the GUI elements the IP camera's current preferences as soon as the streaming process has been started. This is a really short and elegant solution for C# cross-thread operations. The next example will demonstrate this technique as well.

FAQ

Below you can find the answers for the most frequently asked questions related to this topic:

  1. How can I get the URL of the camera?

    You can get the URL from the producer of the camera. (In the 10th tutorial you can find information on how to create an own IP camera discoverer program.)

  2. I have not managed to build the solution. How to solve it?

    • Please set the Target framework property of the project to .NET 4.0.
    • You should add the System.Drawing.dll and OzekiSDK.dll to the references of the solution.
    • Please import the missing classes.
  3. Why does the brightness/contrast/saturation change when I did not order it?

    It is possible that someone else is also using the camera.

  4. I can see the image but all the numbers are on 0 and I can move the scrollbars but nothing happens.

    In this case your camera does not support the modification of the brightness, contrast or saturation.
