Almost all of us know how to take photos from our Camera or SmartPhone, but we do not know how to use all the functions located in the Camera, due to which we try as much as we can but cannot take photos like a Photographer. One such feature is Backlight Compensation. There are hardly any of you who know What is Backlight Compensation? This is because many camera manufacturers often write misleading features in the descriptions of products to sell their products to average consumers like us. The effect of this is that many innocent customers buy those products. Due to which they are not able to use those features even if they want later because they are not there in it.
At the same time, many consumers are unable to use them due to a lack of knowledge about this feature of the camera. There are many other features of similar cameras such as Backlight Compensation (BLC), Highlight Compensation (HLC), Wide Dynamic Range (WDR) which are very important for the camera because by using them properly, you get very quality images. can be found. That's why I thought that why you should not be provided complete information about Backlight Compensation so that you can also know about this camera feature. Then without delay let's start and know what is this Backlight Compensation in Hindi.
What is BackLight Compensation?
The technology of Backlight Compensation (BLC) has come for many years, which means that it is not a new and advanced technology. When it comes to image features, how can we forget about Backlight Compensation? It has a lot of utility in having a better quality of a picture. By having this feature, the overpowering background and bright lights can be easily compensated. Let us understand by example if a person or any object is standing in front of a window or window, or is coming from an outside door, or is standing in a bright area, then in such a situation that person or object It is common to have a lot of natural light behind it. Talking about before BLC, then at that time the camera easily became unstable before these natural lights because more focus of the camera went to that natural light, due to which the person or object seemed very dark. Along with this, the details of the main objects were also lost, due to which it was very difficult to identify their identity.
At the same time, once the feature of Backlight compensation was discovered, then this problem was reduced to about 90%. Because in BLC the video is split into different regions, and a different exposure is applied to each region. That's why it happens that the high or low-level light of the objects in focus is all maintained, due to which the natural bright light does not have much effect in the final picture. In this, the right focus is on the main object. Due to the proper distribution of light, the picture is not too dark and the final output is correct.
How BackLight Compensation Works?
Backlight Compensation is a technical term that refers to the mechanism of the camera to compensate for the backlight and to do so it has to enhance the automatic exposure control in the camera to compensate for the backlight.
For example, you can think about this scene. A person walks into a dimly lit room with a flashlight or torch and puts the focus of that flashlight directly on the camera. Normally it happens that this focus is a very bright light source for the camera (high illumination), due to this the camera reduces its exposure to compensate for brightness – since the scene becomes significantly brighter. This happens that the brightness of the overall scene gets reduced, due to which some parts of the picture become very dark, these are the same parts in which we expect light.
But at the same time, this does not happen in Backlight compensation and the Camera ignores small areas of high illumination in this, due to which a large part of the scene remains bright and the final result is fully visible to us. In this, as much as the bright light is focused on the camera, even then the area of interest also has the same exposure. Therefore, without backlight compensation, the image that occurs in the vicinity of the flashlight (such as an unknown person) cannot be correctly identified by the IP camera. Therefore, due to the presence of Backlight Compensation, most IP cameras automatically compensate for bright light.
What are the Features of Backlight Compensation?
The feature of Backlight Compensation is most used in CCTV cameras or IP cameras. With this, they can identify the intruders very well at night, despite having direct focus.
BLC is a very ideal technique to neutralize images, overpowering backgrounds, and bright lights.
A Digital signal processor (DSP) is used in BLC so that the brightness of the images can be optimized methodically.
• BLC systematically divides the images into different parts, so that the exposure divides into different parts of the picture and our area of interest is not too dark.
What is Auto Backlight Compensation?
Due to the presence of BLC in the camera, it can easily scan the entire area of the frame and find out the average light level.
In this, the working point is based on the general testing of the entire environment. If there is a very bright background with a very dim front image, then the backlight sensation gets activated automatically, and the camera can easily apply light to the dark zone.
With this automatic backlight compensation, a normally dark and unspecific image can be easily converted into a clear and better visibility image.
What is the difference between Backlight compensation and Wide Dynamic Range?
Backlight compensation adjusts the contrast levels of the image, but in Wide Dynamic Range (WDR) the image is exposed at different exposure times.
WDR, therefore, has a lot of compensating differences in contrast/brightness but backlight compensation only handles the brightness level of the picture.
