Sensors vary in type and purpose. They increase the overall functionality of the device, in which they are integrated.

Information about the sensor type of the camera. Some of the most widely used types of image sensors on mobile devices are CMOS, BSI, ISOCELL, etc.

The aperture (f-stop number) indicates the size of the lens diaphragm opening, which controls the amount of light reaching the image sensor. The lower the f-stop number, the larger the diaphragm opening is, hence, the more light reaches the sensor. Usually, the f-stop number specified is the one that corresponds to the maximum possible diaphragm opening.

Focal length is the distance in millimeters from the focal point of the image sensor to the optical center of the lens. The 35 mm equivalent indicates the focal length at which a full-frame camera will achieve an angle of view that's the same as the one of the camera of the mobile device. It is measured by multiplying the native focal length of the camera by the crop factor of the sensor. The crop factor itself can be determined as the ratio between the diagonal distances of the image sensor in the 35 mm camera and a given sensor.

The rear cameras of mobile devices use mainly a LED flash. It may arrive in a single, dual- or multi-light setup and in different arrangements.

One of the main characteristics of the cameras is their image resolution. It states the number of pixels on the horizontal and vertical dimensions of the image, which can also be shown in megapixels that indicate the approximate number of pixels in millions.

Information about the maximum resolution at which the main camera can shoot videos.

The amount of light reaching the image sensor can be controlled with the aperture, designated with the f-number. The lower the f-number, the wider the aperture, the more light reaches the sensor.

The 35 mm focal length equivalent indicates the focal length at which a full-frame camera will achieve a field of view that's the same as the one of the camera of the mobile device. In general, ultra-wide cameras use lenses with focal lengths shorter than 24 mm.

Information about the image resolution of the ultra-wide camera in megapixels.

Additional features of the ultra-wide camera.

The amount of light reaching the image sensor can be controlled with the aperture, designated with the f-number. The lower the f-number, the wider the aperture, the more light reaches the sensor.

The 35 mm focal length equivalent indicates the focal length at which a full-frame camera will achieve a field of view that's the same as the one of the camera of the mobile device. In general, telephoto cameras use lenses with focal lengths longer than 45 mm.

Information about the level of optical zoom of the telephoto camera. The higher the focal length, the more zoomed in the lens will be.
