In one embodiment, the distance sensor 210 may emit a light source of a specific frequency, for example, infrared ray (IR). For example, the wavelength of infrared rays may be 940 nm or 1400 nm.

In one embodiment, the plurality of cameras 230 are arranged to be laterally spaced apart from each other, so that there may be a non-overlapping error range between each shooting range. Additionally, the distance sensor 210 may also have an error range due to the difference in position with the plurality of cameras 230.

FIG. 4 illustrates the capturing range of the plurality of cameras 230 and the sensing range R1 of the distance sensor 210, according to one embodiment.

Referring further to FIG. 4, in one embodiment, the distance sensor 210 is disposed on the side of the plurality of cameras 230, for example, the distance sensor 210 is positioned on the side from each of the plurality of cameras 230. It can be fixed in a spaced position. Accordingly, the detection range (R1) of the distance sensor 210 may be at least partially different from the capturing range (FOV) of each of the plurality of cameras.

Specifically, the detection range (R1) of the single-zone distance sensor 210 according to one embodiment is the shooting range of the telephoto camera (e.g., the third camera 233 and the fourth camera 234) among the plurality of cameras. It may include most of the cameras, but may only include a portion of the shooting range of the wide-angle camera (e.g., the first camera 231) and/or the ultra-wide-angle camera (e.g., the second camera 232) among the plurality of cameras. That is, the distance sensor 210 can only detect distances for objects located in a portion of the shooting range of a plurality of cameras, and can detect distances for objects in the remaining portion of the shooting range outside the detection range (R1). does not exist. Accordingly, the electronic device 200 may not be able to automatically focus on an object located in the capturing range of a plurality of cameras, or it may be difficult to switch to a camera with an appropriate focal length.

Figure 5 compares the shooting range of a wide-angle camera and the detection range of a single-zone distance sensor for each distance, according to an embodiment.

The multi-zone distance sensor with a relatively wide angle of view in Figure 6 generates some error between the detection range (R1) and the shooting range of the wide-angle camera at close range, but the detection range (R1) of the distance sensor is greater than that of the wide-angle camera. It can cover a significant amount of the range. The field of view of a multi-zone distance sensor can be relatively expanded than that of a single-zone distance sensor to cover most of the preview area of multiple cameras.

In contrast, the single-zone distance sensor with a relatively narrow field of view in Figure 5 covers only a small portion of the wide-angle camera's shooting range, and at a close distance (e.g., 100 [mm]), it is located on the right side of the wide-angle camera's shooting range. It can barely cover the entire area and the upper left area. Additionally, since a single-zone distance sensor can provide only one distance value, it cannot detect the distance to an object in an environment where objects are mixed at a close and far distance.
