Which of the following is a function of a gyroscope in mobile devices?

A gyroscope in mobile devices primarily serves the function of stabilizing images, which is crucial for enhancing the clarity and quality of photographs and videos. This stabilization occurs by detecting the orientation and angular velocity of the device, allowing it to adjust accordingly to minimize blur caused by user movement.

When taking photos or recording videos, any slight movement of the device can cause distortion. A gyroscope helps correct this by providing data that aids in stabilizing the image during capture. This function is particularly beneficial in mobile devices used for photography and videography, making it an essential component in enhancing overall user experience.

The other functions listed do not pertain to the primary functionalities of a gyroscope. Calculating pixel density is related to display technology rather than motion sensing. Converting analog signals typically involves different components such as ADCs (Analog-to-Digital Converters) rather than gyroscopic sensors. Controlling cursor movement is more commonly associated with touchscreens or trackpads rather than gyroscopic technology.
