Autofocus accuracy and speed using thermal input information

A method, comprising:

• providing, in an imaging device, an image sensor;
• providing a lens assembly including a lens whose distance from the image sensor is adjustable from a minimum stroke distance to a maximum stroke distance, the minimum stroke distance being to focus an object at a maximum distance from the imaging device on the image sensor, and the maximum stroke distance being to focus the object at a minimum distance from the imaging device on the image sensor;
• instantiating on the imaging device a plurality of auto focus tables, each auto focus table being correlated to a particular temperature in an operating temperature range of the imaging device, wherein each auto focus table provides a temperature compensated correlation of a first stroke distance associated with the object at the maximum distance from the imaging device, and a second stroke distance associated with the object at the minimum distance from the imaging device;
• selecting a first auto focus table associated with a first temperature of the imaging device;
• and
• providing a first auto focus for the object based upon the first auto focus table.

An information handling system, comprising:

• a processor;
• an imaging device including an image sensor, a lens assembly, and a temperature sensor;
• and
• a memory to store a plurality of auto focus tables, each auto focus table being correlated to a particular temperature in an operating temperature range of the imaging device;
• wherein:
• the lens assembly includes a lens whose distance from the image sensor is adjustable from a minimum stroke distance to a maximum stroke distance, the minimum stroke distance being to focus an object at a maximum distance from the imaging device on the image sensor, and the maximum stroke distance being to focus the object at a minimum distance from the imaging device on the image sensor;
• and
• the processor receives a first temperature from the temperature sensor, selects a first auto focus table associated with the first temperature, and provides a first auto focus for the object based upon the first auto focus table.
