The Dhaka Times Desk There are many things we don't know about face detection technology in digital cameras. It is actually used for a completely different purpose.
In this case, you can manually detect the face from the preview option of the photo taken by the camera and give it your desired effect and finishing touch. A simple logic diagram of a digital camera with face detection technology basically looks like this. Learn about the features and uses of this face detection technology today.
Face selection and tracking
After fixing your focus on the subject's face, you can also choose the selection angle proportional to that face. After selecting the face and tracking function you need to configure the following two settings. Ori frame should be selected for face detection. To confirm this detection you need to go to print share button option and select face detect.
AF point zooming
I have already mentioned the use of AF form. With the help of this, you can select a specific face while taking a picture or after. Another nice feature in this AF point is the AF point zooming. You can use this zooming option during or after taking the picture whenever you want. You can use this technology to fix photo focusing and correct someone's expression. If you are an amateur photographer, then no problem. Moreover, this zooming option will help you to focus even in the case of macro mode.
Face Detection (AF/AE/FE/WB)
This face detection technology adds more benefits to digital cameras. Apart from just face detection, you can manually or auto setup fine tasks like focus, exposure, white balance. Automatic face illumination during flash makes focusing even more convenient. Focusing and phasing are always placed in a favorable position for this illumination.
Red eye correction
From now on, no more scrubbing in Photoshop if you wear red eye when going for a photo. Resolve the red eye effect using face detection technology. In some exceptional cases it automatically detects and corrects these red eyes. Again, if you want, you can manually detect and correct it easily. In this case you can also make corrections with the help of red eye shadow option. For that you have to choose. Another thing is that once the correction is done, the image will be automatically saved to the memory card. You don't need to go through the hassle of doing it manually again.
trimming
Camera-side trimming option is attached here if you want to trim a specific part of the captured image. After the specific part is selected by face detection in the AF frame. Multiple image detection is also performed in some cases. The print/share option can also be used to switch this frame of trimming from one face to another. Much like the tab button. Moreover, another interesting thing is that it is possible to give a nicer finishing touch to the pictures taken by other cameras through this face detection technology.
Focus checking
Focusing can be done better than before. You can check the focus during or after taking the picture. If the focus is not where you want it, you can play back and move the focus to another place. Source: Ittefaq.
