IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18377318 titled 'IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD

Simplified Explanation

  • An image processing device and method for applying a deblocking filter process effectively.
  • A pixel value of 255 changes to 159 after a conventional deblocking process, causing significant changes.
  • A clipping process with a value of 10 is applied in strong filtering to limit the change in pixel value.
  • The pixel value of 255 before the deblocking process becomes 245 after the clipping process, reducing the change.
  • This technology can be used in image processing devices.

Potential Applications

  • Video processing systems
  • Image editing software
  • Digital cameras

Problems Solved

  • Significant changes in pixel values after deblocking processes
  • Inaccurate filtering leading to distorted images
  • Loss of image quality due to excessive filtering

Benefits

  • Improved image quality
  • Reduced artifacts in images
  • More accurate filtering processes


Original Abstract Submitted

The present technology relates to an image processing device and an image processing method which allow a deblocking filtering process to apply filtering appropriately. A pixel (p0) of which the value is 255 (solid line) before a deblocking process changes greatly to 159 (dot line) after a conventional deblocking process. Therefore, a clipping process having a clipping value of 10 is performed in strong filtering, whereby the pixel (p0) of which the value is 255 (solid line) before the deblocking process becomes 245 (bold line). Thus, a change in the pixel value occurring in the conventional technique can be suppressed as much as possible. This disclosure can be applied to an image processing device, for example.
