FOCUS DETERMINATION DEVICE, IRIS AUTHENTICATION DEVICE, FOCUS DETERMINATION METHOD, AND RECORDING MEDIUM - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240104923 titled 'FOCUS DETERMINATION DEVICE, IRIS AUTHENTICATION DEVICE, FOCUS DETERMINATION METHOD, AND RECORDING MEDIUM
Simplified Explanation
The patent application describes a focus determination device that uses filter processing to determine if an iris image is in focus.
- An acquisition acquires an iris image, including an iris of a user.
- A filter processing unit applies an image processing filter in a shape decided based on the shape of a light applied to the user to the iris image.
- A focus determination unit determines if the iris image is in focus based on the filtered image.
Potential Applications
This technology could be used in:
- Biometric security systems
- Medical imaging devices
Problems Solved
- Accurate focus determination in iris recognition systems
- Improved image quality for iris scanning
Benefits
- Enhanced security through precise iris recognition
- Increased reliability in medical diagnostics
Potential Commercial Applications
Optimizing focus determination technology for:
- Access control systems
- Healthcare facilities
Possible Prior Art
One possible prior art could be the use of traditional image processing techniques for focus determination in iris recognition systems.
Unanswered Questions
How does the filter processing unit determine the shape of the filter based on the shape of the light applied to the user?
The patent application does not provide specific details on the process of determining the shape of the filter based on the shape of the light. Further information on this aspect would be beneficial for understanding the technology better.
What are the specific parameters used by the focus determination unit to determine if the iris image is in focus?
The patent application does not elaborate on the exact parameters or criteria used by the focus determination unit to make its decision. More information on this would help in evaluating the effectiveness of the technology.
Original Abstract Submitted
in a focus determination device, an acquisition acquires an iris image including an iris of a user. a filter processing unit performs a filter processing by applying an image processing filter in a shape decided based on a shape of a light applied to the user to the iris image. a focus determination unit determines whether or not the iris image is in focus based on the iris image resulting from the filter processing.
