IMAGE SENSOR AND ELECTRONIC APPARATUS INCLUDING THE IMAGE SENSOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 18227095 titled 'IMAGE SENSOR AND ELECTRONIC APPARATUS INCLUDING THE IMAGE SENSOR

Simplified Explanation

The provided patent abstract describes an image sensor with a pixel array consisting of imaging pixels and autofocusing pixels, as well as a lens array with micro lenses and super lenses. Each imaging pixel selectively absorbs light of different wavelength bands (red, green, and blue) using meta-photodiodes.

  • The patent describes an image sensor with a pixel array and a lens array.
  • The pixel array includes imaging pixels and autofocusing pixels.
  • The lens array consists of micro lenses facing the imaging pixels and super lenses facing the autofocusing pixels.
  • Each imaging pixel has meta-photodiodes for selectively absorbing light of red, green, and blue wavelength bands.

Potential Applications:

  • This technology can be used in digital cameras, smartphones, and other imaging devices to improve image quality and autofocus capabilities.
  • It can be applied in medical imaging devices for capturing high-resolution images with accurate color representation.
  • The image sensor can be used in surveillance systems for enhanced image capture and autofocus functionality.

Problems Solved:

  • The image sensor addresses the challenge of accurately capturing different wavelength bands (red, green, and blue) for improved color reproduction.
  • The inclusion of autofocusing pixels helps in achieving precise focus in various lighting conditions.
  • The lens array with micro lenses and super lenses assists in enhancing the overall image quality and autofocus performance.

Benefits:

  • The image sensor provides improved image quality by selectively absorbing light of different wavelength bands.
  • The autofocusing pixels contribute to accurate and fast autofocus functionality.
  • The use of micro lenses and super lenses helps in capturing sharper and more detailed images.
  • The technology enables better color reproduction and enhances the overall imaging experience.


Original Abstract Submitted

Provided is an image sensor including a pixel array including a plurality of imaging pixels and a plurality of autofocusing pixels, and a lens array including a plurality of micro lenses facing the plurality of imaging pixels, respectively, and one or more super lenses facing the plurality of autofocusing pixels, wherein each imaging pixel of the plurality of imaging pixels includes a first red meta-photodiode configured to selectively absorb light of a red wavelength band, a first green meta-photodiode configured to selectively absorb light of a green wavelength band, and a first blue meta-photodiode configured to selectively absorb light of a blue wavelength band.
