AUTOFOCUS ACCURACY AND SPEED USING THERMAL INPUT INFORMATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17837257 titled 'AUTOFOCUS ACCURACY AND SPEED USING THERMAL INPUT INFORMATION

Simplified Explanation

The patent application describes an imaging device that includes an image sensor, lens assembly, temperature sensor, and processor. The lens assembly has an adjustable distance from the image sensor. The temperature sensor determines the temperature of the device, and the processor uses this information to select an auto focus table and provide auto focus for the object.

  • The imaging device has an adjustable lens assembly that can change the distance between the lens and image sensor.
  • A temperature sensor is included to determine the temperature of the device.
  • The processor uses the temperature information to select an auto focus table.
  • The auto focus table provides a correlation between the object distance and the stroke distance of the lens assembly.
  • The auto focus table is temperature compensated, meaning it takes into account the temperature of the device.
  • The processor uses the selected auto focus table to provide accurate auto focus for the object.

Potential Applications

  • Photography and videography equipment
  • Surveillance cameras
  • Medical imaging devices
  • Industrial inspection systems

Problems Solved

  • Inaccurate auto focus due to temperature variations
  • Ensuring consistent and reliable auto focus performance in different temperature conditions

Benefits

  • Improved accuracy and reliability of auto focus
  • Temperature compensation ensures consistent performance
  • Enhanced image quality and clarity


Original Abstract Submitted

An imaging device includes an image sensor, a lens assembly, a temperature sensor, and a processor. 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 temperature sensor determines a temperature of the imaging device. The processor instantiates auto focus tables that are each correlated to a temperature, receives at temperature from the temperature sensor, selects an auto focus table associated with the temperature, and provides an auto focus for the object based upon the auto focus table. 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.
