Photographing Method and Electronic Device - A simplified explanation of the abstract

This abstract first appeared for US patent application 18253551 titled 'Photographing Method and Electronic Device

Simplified Explanation

The patent application describes a method for operating an electronic device with two cameras to capture and display images with a changing zoom ratio. Here are the key points:

  • The method detects when the zoom ratio gradually changes within a specific range.
  • The zoom ratio in this range is lower than the optical zoom ratio of the second camera.
  • The difference between the zoom ratio in the range and the optical zoom ratio is within a certain value.
  • The method crops the image captured by the first camera to create a preview image with a gradually changing field of view (FOV) size.
  • The preview image with the changing FOV size is displayed on the device's screen.

Potential applications of this technology:

  • Mobile phones or tablets with dual cameras can use this method to provide a smooth transition between different zoom levels.
  • It can be useful in photography or videography applications where users want to preview how the FOV changes as they zoom in or out.
  • This method can enhance the user experience when using video conferencing or video streaming applications by providing a more dynamic preview.

Problems solved by this technology:

  • The method solves the problem of abrupt changes in the field of view when zooming in or out, providing a smoother and more natural transition.
  • It addresses the challenge of maintaining image quality while changing the zoom ratio by cropping the captured image to create a preview with a changing FOV size.

Benefits of this technology:

  • Users can have a better understanding of how the field of view changes as they zoom in or out, allowing for more precise framing of photos or videos.
  • The gradual change in FOV size provides a more visually pleasing experience for users.
  • The method helps maintain image quality by utilizing the optical zoom capabilities of the second camera while smoothly transitioning between different zoom levels.


Original Abstract Submitted

In accordance with an embodiment, a method of operating an electronic device comprising a screen, a first camera, and a second camera, includes: detecting that a zoom ratio gradually changes within a first ratio range, wherein the zoom ratio in the first ratio range is less than an optical zoom ratio of the second camera, and a ratio difference between the zoom ratio within the first ratio range and the optical zoom ratio of the second camera is less than a first value; cropping an image captured by the first camera to obtain a preview image whose field of view (FOV) size gradually changes; and displaying on the screen, the preview image whose FOV size gradually changes.
