Auto-focus calibration for image capture device

A non-transitory computer-readable storage medium

• comprising instructions that when executed cause one or more processors to:
• detect a focus condition of an image capture device;
• control movement of a lens of the image capture device among multiple lens positions;
• select one of the multiple lens positions when the focus condition is detected, based on a focus value, as a selected lens position;
• adjust an auto-focus lens position search range based on the selected lens position;
• and
• store, in the image capture device, the adjusted auto-focus lens position search range.

A method comprising:

• detecting a focus condition of an image capture device;
• moving a lens of the image capture device among multiple lens positions;
• selecting one of the lens positions based on a focus value as a selected lens position;
• storing the selected lens position as a drive value for a lens actuation module that moves the lens;
• and
• adjusting an auto-focus lens position search range based on the selected lens position when the focus condition is detected.

A method comprising:

• detecting a first focus condition of an image capture device;
• detecting a second focus condition of the image capture device;
• moving a lens of the image capture device among multiple lens positions;
• selecting one of the lens positions based on a focus value as a selected lens position;
• adjusting an auto-focus lens position search range based on an auto-focus calibration process, wherein a near focus bound of the search range is adjusted when the first focus condition is detected and a far focus bound of the search range is adjusted when the second focus condition is detected;
• adjusting the auto-focus lens position search range based on the selected lens position when the first focus condition is detected;
• and
• adjusting the auto-focus lens position search range based on the selected lens position when the second focus condition is detected,
• wherein the first focus condition is a focus condition associated with an indoor environment, and the second focus condition is a focus condition associated with an outdoor environment.
