METHOD AND DEVICE FOR GENERATING ALL-IN-FOCUS IMAGE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17954871 titled 'METHOD AND DEVICE FOR GENERATING ALL-IN-FOCUS IMAGE
Simplified Explanation
The patent application describes a method and device for generating an all-in-focus image. Here is a simplified explanation of the abstract:
- The method involves capturing a scene using a phase detection image sensor to obtain a scene image and a phase detection image.
- A blur kernel is determined based on the phase detection image and a mapping relationship that indicates the depth and distribution of the blur kernel.
- The scene image is then deblurred using the determined blur kernel to generate the all-in-focus image.
Potential applications of this technology:
- Photography: This technology can be used in cameras to capture images with a greater depth of field, resulting in sharper and more detailed photos.
- Microscopy: It can be applied in microscopy to capture clear and focused images of microscopic samples, improving the accuracy of analysis and research.
- Medical imaging: The method can be used in medical imaging devices to capture high-quality images of patients, aiding in diagnosis and treatment planning.
Problems solved by this technology:
- Depth of field limitations: Traditional cameras have a limited depth of field, resulting in some parts of the image being out of focus. This technology solves this problem by generating an all-in-focus image.
- Blurry images: The method addresses the issue of blurry images caused by camera shake or subject movement by deblurring the scene image using the determined blur kernel.
Benefits of this technology:
- Improved image quality: By generating an all-in-focus image, this technology improves the overall sharpness and clarity of the captured images.
- Enhanced accuracy: In applications such as microscopy and medical imaging, the technology ensures that important details are captured accurately, leading to more precise analysis and diagnosis.
- Simplified image processing: The method eliminates the need for complex post-processing techniques to achieve focus stacking or image fusion, simplifying the overall image processing workflow.
Original Abstract Submitted
A method and device for generating an all-in-focus image are disclosed. A method of generating an all-in-focus image includes obtaining a scene image and a phase detection image by capturing a scene using a phase detection image sensor; determining a blur kernel based on the phase detection image and a particular mapping relationship indicating a depth and a blur kernel distribution; and generating the all-in-focus image by deblurring the scene image using the blur kernel.
