AUTOMATIC FOCUS DETECTION METHOD OF CAMERA AND ELECTRIC DEVICE SUPPORTING SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17957541 titled 'AUTOMATIC FOCUS DETECTION METHOD OF CAMERA AND ELECTRIC DEVICE SUPPORTING SAME
Simplified Explanation
The abstract describes an electronic device with a camera that can adjust focus based on depth information. Here are the key points:
- The device has a camera that can adjust focus.
- It also has a distance extraction device to measure depth.
- The processor in the device performs the following steps:
* Takes a first image using the camera. * Sets a region of interest for focus detection in a part of the image. * Obtains depth information for at least one pixel in the image. * Sets a second region of interest in another part of the image based on differences in depth. * Captures an image with focus determined for the second region of interest.
Potential applications of this technology:
- Improved autofocus in cameras and smartphones.
- Depth-based focus adjustment in virtual reality and augmented reality devices.
- Enhanced depth perception in autonomous vehicles and drones.
Problems solved by this technology:
- Accurate focus adjustment based on depth information.
- Improved image quality by capturing images with the correct focus.
- Simplified user experience by automating focus adjustment.
Benefits of this technology:
- Sharper and clearer images with accurate focus.
- Enhanced depth perception for various applications.
- Improved user experience with automated focus adjustment.
Original Abstract Submitted
An electronic device includes a camera device configured to adjust a focus; a distance extraction device; and a processor configured to: obtain a first image using the camera device; set a first region of interest for focus detection in a portion of the first image; obtain first depth information using the distance extraction device, the first depth information including a depth distance corresponding to at least one pixel included in the first image; set a second region of interest in another portion of the first image based on at least two portions which differ in depth distance being included in the first region of interest based on the first depth information; and capture an image based on a focus determined corresponding to the second region of interest.
