METHOD FOR PROCESSING IMAGE DATA OF AN IMAGE SENSOR AND IMAGE PROCESSOR UNIT AND COMPUTER PROGRAM - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240015407 titled 'METHOD FOR PROCESSING IMAGE DATA OF AN IMAGE SENSOR AND IMAGE PROCESSOR UNIT AND COMPUTER PROGRAM

Simplified Explanation

The invention is a method for processing image data captured by an image sensor. The image sensor includes a pixel matrix that provides image pixel data, and within this matrix, there are phase detection pixels located at specific positions. The image pixel data includes phase detection information for these phase detection pixels. The method involves calculating the image pixel data for the pre-defined locations of the phase detection pixels using a function that can have either symmetric or asymmetric positioning of the phase detection in the color channel.

  • The method is used for processing image data captured by an image sensor with phase detection pixels.
  • The image sensor has a pixel matrix that provides image pixel data.
  • The pixel matrix includes phase detection pixels located at specific positions.
  • The image pixel data includes phase detection information for these phase detection pixels.
  • The method involves calculating the image pixel data for the pre-defined locations of the phase detection pixels.
  • The calculation is performed using a function that can have either symmetric or asymmetric positioning of the phase detection in the color channel.

Potential applications of this technology:

  • Improved autofocus: The use of phase detection pixels allows for more accurate and faster autofocus in cameras.
  • Depth sensing: The phase detection information can be used to estimate the depth of objects in the image, enabling applications such as augmented reality and 3D mapping.
  • Image stabilization: The phase detection pixels can help in stabilizing images by providing information about the movement of the camera.

Problems solved by this technology:

  • Inaccurate autofocus: Traditional autofocus methods may not be as precise or fast as using phase detection pixels.
  • Depth estimation challenges: Estimating depth in images can be difficult, but the phase detection information can help overcome this challenge.
  • Image blur: The information from the phase detection pixels can aid in reducing image blur caused by camera movement.

Benefits of this technology:

  • Improved image quality: The use of phase detection pixels and the calculated image pixel data can result in sharper and clearer images.
  • Faster autofocus: The method allows for faster and more accurate autofocus, improving the overall user experience.
  • Enhanced depth perception: The phase detection information enables better depth estimation, leading to more immersive augmented reality experiences and accurate 3D mapping.
