autofocus

A feature of all digital cameras that automatically aligns the lens to make the subject in the image sharp (in focus). Pressing the shutter button halfway down generally displays a rectangle in the viewing screen indicating where the camera has identified the subject. See focal length.

In the bisected laser-based autofocusing method, when defocus value varies from "inner focus," "outer focus," and "in focus," the semicircular laser spot can theoretically image in three different states as illustrated in Figure 1.
A High Precision Laser-Based Autofocus Method Using Biased Image Plane for Microscopy
In PA systems used to perform autofocusing with such devices, the image obtained from the camera is processed by using an appropriate focusing algorithm, and the lens position which yields the clearest image is sought [25], [32-34].
A New Autofocusing Method Based on Brightness and Contrast for Color Cameras
An autofocusing method based on image processing is applicable for processing an image sequence, such as taking images of the target with multiple focal plane positions.

The X-A2 features Fujifilm's newly developed Eye Detection AF, Auto Macro AF and Multi-Target MULTI AF for fast and accurate autofocusing. It's also the first X Series model to sport a 175-degree tilting LCD making it easier to take selfies and it comes with the new XC16-50mm F3.5-5.6 OIS II kit lens, which has a class-leading minimum working distance of 15cm (approx.

Earning special praise, however, was the EOS 70D's Dual Pixel CMOS AF, which the judges called a "breakthrough." The innovative autofocusing technology makes possible improved tracking capabilities when shooting video to ensure smooth focusing performance similar to that achieved by video camcorders, and fast autofocusing performance when capturing stills during Live View shooting.
