Classification: CPC H  G | IPC H

Claim 11:
12. A non-transitory computer-readable medium having stored thereon computer-executable instructions, which when executed by a processor of an imaging device, cause the processor to execute operations, the operations comprising:
receiving, by a plurality of pixels, modulated light modulated by a color filter array and a coded mask, wherein
the color filter array includes a plurality of type of color filters that transmit light of different wavelength bands,
the coded mask includes a plurality of type of band pass filters that are arranged in a two-dimensional grating pattern,
the plurality of type of band pass filters includes a first type of band pass filter and a second type of band pass filter,
a size of the first type of band pass filter is different from a size of the second type of band pass filter, and
the plurality of type of band pass filters is configured to transmit light of different wavelength bands;

generating observation signal data based on the received modulated light, wherein
the observation signal data comprises a pixel value for each of the plurality of pixels, and
the plurality of pixels includes a plurality of first pixels on which the modulated light of a first wavelength band is incident and a plurality of second pixels on which the modulated light of a second wavelength band different from the first wavelength band is incident;

reconstructing the generated observation signal data, wherein the observation signal data includes first channel data including the pixel values generated by the plurality of first pixels and second channel data including the pixel values generated by the plurality of second pixels;
restoring, based on a binary matrix operation process, the first channel data and the second channel data; and
generating image data based on the restored first channel data and the second channel data.
