Image Transformation Method and Apparatus - A simplified explanation of the abstract
This abstract first appeared for US patent application 18147391 titled 'Image Transformation Method and Apparatus
Simplified Explanation
The patent application describes an image transformation method that improves the appearance of a target person's face in a captured image. Here are the key points:
- The method starts by capturing a first image using a front-facing camera, focusing on the target person's face in a specific scenario.
- The distance between the target person's face and the camera is measured and recorded as the target distance.
- If the target distance is below a certain threshold, the method applies distortion correction to the first image as a form of processing.
- The distortion correction is based on the target distance, aiming to make the face in the image appear more realistic and closer to the actual appearance of the target person.
- The result is a second image where the target person's face looks more natural and closer to how it would appear in real life.
Potential Applications
- Improving the quality of selfies or front-facing camera images by correcting distortions caused by close proximity to the camera.
- Enhancing video calls or video conferencing by making the faces of participants look more natural and less distorted when they are close to the camera.
Problems Solved
- The method addresses the issue of distorted facial appearance in images captured at close distances using front-facing cameras.
- It solves the problem of unrealistic facial proportions or distortions that can occur when the face is too close to the camera.
Benefits
- Provides a more accurate representation of a person's face in images captured at close distances.
- Enhances the overall quality and realism of images taken with front-facing cameras.
- Improves user satisfaction with selfies, video calls, and other applications that rely on front-facing camera technology.
Original Abstract Submitted
An image transformation method includes obtaining a first image for a target scenario by using a front-facing camera, where the target scenario includes a face of a target person; obtaining a target distance between the face of the target person and the front-facing camera; and when the target distance is less than a preset threshold, performing first processing on the first image to obtain a second image. The first processing includes performing distortion correction on the first image based on the target distance. The face of the target person in the second image is closer to a real appearance of the face of the target person than the face of the target person in the first image.
