What is Backlight Compensation?

Most of us know how to take photos from our own camera or from a SmartPhone, but we do not know how to use all the functions in the camera, due to which we try as much as we can but we cannot take a photo like a photographer. One such feature is Backlight Compensation. There is hardly any of you who knows what Backlight Compensation is? 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 naive spears customers buy those products. Due to which they are not able to use those features even after they want it, because it is not there in it.

At the same time there are also many consumers, who are unable to use them due to lack of knowledge about this feature of the camera. There are many other features of the camera as well, 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 can get very high quality images. Can be found. So I thought why should you all be provided complete information about Backlight Compensation so that you too can get to know about this camera feature. Then, without delay, let's start and know what the Backlight Compensation is in Hindi.

The technology of backlight compensation (BLC) has come for many years, meaning it is not a new and advanced technology. When it comes to image feature, how can we forget about the Backlight Compensation. There is a lot of utility in having a better quality of a picture of it. With this feature, background overpowering and bright lights can be easily compensated. Let us understand by example, if a man or an object is standing in front of a window or window, or is walking through an outside door, or is standing in one bright area, then in that case that person or object It is common to have a lot of natural light behind. Talking about before BLC, at that time the camera easily became unstable before these natural lights because more focus of the camera used to go on that natural light, which made the person or object look very dark. In addition, the details of the main objects were also very much loss, which made it very difficult to identify their identity.

At the same time, once the feature of Backlight compensation was discovered, this problem was reduced by about 90%. Because video in BLC is split into different regions, and each region is applied a different exposure. Therefore it happens that the high or low level light of the objects that are in focus is all maintained, due to which the effect of natural bright light is not seen in the last picture. In this, the right focus is placed on the main object. Due to the light being properly distributed, the picture does not darken and the final output is correct.

How does BackLight Compensation work?

Backlight Compensation is a technical term that refers to the mechanism of the camera by which the camera compensates the backlight and to do this it has to increase the automatic exposure control in the camera to compensate the backlight.

For example you can think of this scene. A person enters a walk in a dimly lit room with a flashlight or torch and he puts the focus of that flashlight directly on the camera. Normally, this is a very bright light source for the camera (high illumination), this reduces the camera's exposure to compensate for the brighness - since the scene has become very significantly brighter. This happens that the brightness of the overall scene is reduced due to which some parts of the picture become very dark, these are the parts in which we expect to be light.

But the same does not happen in the backlight compensation and the camera ignores small areas of high illumination in it, which makes the major part of the scene bright and the final outcome is completely visible. In this, the more 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 is surrounding the flashlight (such as an unknown person) cannot be correctly identified by the IP Camera. Therefore, due to the backlight compensation, most IP cameras automatically compensate for bright light.
