Abstract

Systems and methods for adjusting the frame rate or other settings of a video camera device operably connected to a computing device are discussed. Embodiments disclosed herein include features such as detecting a camera activation event, acquiring location information about the location of the computing device, determining an AC power frequency associated with the device location or with a power source used by the device, determining ambient lighting conditions near or around the device, identifying a camera frame rate meant to reduce or avoid flicker that would otherwise be caused by a mismatch between AC frequency and camera frame rate, and setting the frame rate of the camera to the identified rate. Embodiments may include some or all of the features noted above, as well as additional features described herein.

First claim

The invention claimed is:

1. A method for adjusting the frame rate of a video camera device operably connected to a computing device, the method comprising:
in response to a video camera activation event detected by the computing device, acquiring information about an Alternating Current (AC) power frequency associated with a location of the computing device;
calculating a frame rate setting suitable to avoid flicker for the AC power frequency of the location;
comparing the ca…
