Laser autofocus technology is one of the most helpful features for today’s smartphones as it brings more stability in focusing on the main subject so users can easily take the best shots without struggling with focusing on the objects and taking sharper images.
Autofocus evolution
When you click photos from your smartphone, you will also want a crisper and clearer photo, and to make this happen, the smartphone manufacturers are adding a special laser autofocus sensor that helps you focus on the main subject without adjusting the three devices simultaneously. So here the role comes of auto-focus; let’s see how it evolved– When taking photos of an object, the camera will capture the light coming from it; along with this, a convex lens is also used to focus incoming light onto a CMOS sensor. After taking the light, it digitizes it and turns it into a JPEG photo that’s saved on your smartphone.
In earlier days, smartphones’ cameras mostly had fixed focus because the earlier smartphones only had fixed autofocus. Due to this, the photos taken by these cameras have fewer details, and that’s why the basic digital camera beats them easily. Still, now smartphones have a newly developed autofocus technology, which brings a new technology to the devices to get a more stable focus on objects on focus. There are types of Autofocus, including Contrast detection autofocus, phase detection autofocus, and laser autofocus.
Galaxy S24 is equipped with powerful ToF sensor technology
Laser auto-focus is the new method of autofocus technology, but to make it more powerful, the company has upgraded it with the redesigned 3D tof(time of flight) sensor, which provides the data to the phone in the form of a 3D map which makes it more accurate and provides better depth in contrast detection and Phase detection auto-focus.
In simple words, it emits its own beam of infrared light towards the object. Then, with the computational power, it calculated the distance to the object, and according to the analysis, it accurately focused the objects, and due to its own bean, it works efficiently even in the dark. So, to take advantage of the newly developed autofocus, Samsung has integrated it into the Galaxy S24 devices as well.
