Determining camera auto-focus settings

A computer-implemented method, comprising:

• determining a tilt angle of a camera of a computing device relative to an axis;
• identifying a tilt angle range from a plurality of predetermined tilt angle ranges that include the tilt angle;
• determining a first focal length setting for the camera based on first association data associating the tilt angle range and the first focal length setting;
• determining an adjustment increment for an autofocus scan range algorithm based on second association data associating the adjustment increment and the tilt angle range;
• and
• determining a second focal length setting for the camera by using the adjustment increment according to the autofocus scan range algorithm.

A computing device comprising:

• a processor;
• a camera;
• a memory device including instructions that, upon execution by the processor, cause the computing device to:
• determine a tilt angle of the camera relative to an axis;
• identify a tilt angle range from a plurality of predetermined tilt angle ranges that include the tilt angle;
• determine a first focal length setting for the camera based on a first association data associating the tilt angle range and the first focal length setting;
• determine an adjustment increment for an autofocus scan range algorithm based on second association data associating the adjustment increment and the tilt angle range;
• and
• determine a second focal length setting for the camera by using the adjustment increment according to the autofocus scan range algorithm.
