What does 13 million super wide angle mean?

13 million ultra-wide angle means that the pixel shot by a mobile phone is13 million, and the ultra-wide angle technology is applied.

The resolution of a13 megapixel photo is 3 120*4208.

Display resolution (screen resolution) is the accuracy of screen image, which refers to how many pixels the display can display. Because the points, lines and surfaces on the screen are all composed of pixels, the more pixels a display can display, the finer the picture will be, and the more information can be displayed on the same screen area, so the resolution is a very important performance index. ?

Super wide angle can be understood from the following four aspects.

1. According to the definition, the focal length of a wide-angle lens is 28mm-35mm and the viewing angle is 76-64; Compared with the general lens, the wide-angle lens has a wide field of view and a long depth of field, which is used for general photography and general landscape photography. More suitable for taking photos of larger scenes, such as architecture, scenery and other themes; The focal length of the super wide-angle lens is 15mm-24mm, and the viewing angle is between 1 10-84.

2. Simply put, super wide-angle refers to being able to shoot more scenes and show larger scenes in the same scene, while the photos taken by non-wide-angle lenses are more like wide-angle photos and intercept a middle area;

3. Another feature of wide-angle lens is that it can emphasize the distance of the scene. After highlighting the far-near contrast, the contrast of the photo can be turned on. That is to say, the things shot by wide-angle lens are layered, big near and small far, which have a perspective effect in vision and can even be deformed. Of course, this is not desirable in photography, but using a wide-angle lens to exaggerate appropriately can discharge the originally inconspicuous things.

4. The wider the angle, the better, as long as it doesn't turn into a fisheye. In terms of wide-angle numbers, the smaller the number, the larger the wide angle. For example, the wide angle of 14 is greater than 28, and 28 is greater than 35.
