AUTOFOCUSING TECHNIQUES FOR IMAGE SENSORS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17931080 titled 'AUTOFOCUSING TECHNIQUES FOR IMAGE SENSORS
Simplified Explanation
The patent application describes systems and techniques for determining lens positions based on light and infrared focus values.
- Moving a lens to a first position
- Determining a light focus value for the first image
- Determining an infrared (IR) focus value for the first image
- Comparing IR focus value to light focus value
- Moving the lens to a second position based on the comparison
- Determining light and IR focus values for the second image
- Calculating a focused lens position based on the values and a threshold focus value
Potential Applications
- Camera autofocus systems - Optical equipment calibration - Robotics vision systems
Problems Solved
- Ensuring accurate focus in imaging systems - Improving image quality in various applications - Enhancing automation processes
Benefits
- Increased precision in lens positioning - Improved image sharpness and clarity - Enhanced performance of imaging devices
Original Abstract Submitted
Systems and techniques are described for determining one or more lens positions. For instance a process can include moving a lens to a first lens position, determining a first light focus value for a first image captured at the first lens position, determining a first infrared (IR) focus value for the first image captured at the first lens position, determining whether the first IR focus value exceeds the first light focus value, moving the lens to a second position based on whether the first IR focus value exceeds the first light focus value, determining a second light focus value for a second image captured at the second position, determining a second IR focus value for a second image captured at the second position, and determining a focused lens position based on the second light focus value, the second IR focus value, and a threshold focus value.
