IMAGING SYSTEM AND METHOD EXECUTED BY IMAGING SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18357113 titled 'IMAGING SYSTEM AND METHOD EXECUTED BY IMAGING SYSTEM

Simplified Explanation

The patent application describes an imaging system that uses compressed sensing technology.

  • The system includes a filter array with different types of filters that have different transmission spectra.
  • An image sensor captures light that passes through the filter array and generates image data.
  • A processing circuit uses the image data to generate hyperspectral image data, which includes images corresponding to four or more bands in a specific wavelength range.
  • The processing circuit also uses a reconstruction table, determined based on the spatial distribution of the filter transmission spectra, to generate the hyperspectral image data.
  • A light source emits reference light with a wavelength in one of the four or more bands, which is used for calibration to correct the reconstruction table.
  • The processing circuit corrects the reconstruction table based on reference image data generated by the image sensor when detecting the reference light.


Original Abstract Submitted

An imaging system is an imaging system using a compressed sensing technology, and includes a filter array including types of filters different from one another in transmission spectrum, an image sensor that generates image data based on light that passes through the filter array, a processing circuit that generates hyperspectral image data including images corresponding to four or more bands included in a target wavelength region on the basis of the image data and a reconstruction table decided on the basis of a spatial distribution of the transmission spectra of the types of filters, and a light source that emits reference light used for calibration for correcting the reconstruction table and having a wavelength of at least one of the four or more bands, and the processing circuit corrects the reconstruction table on the basis of reference image data which the image sensor generates by detecting the reference light.
