1. An imaging device, comprising:
a coded mask including a plurality of kind of band pass filters that are arranged in a two-dimensional grating pattern, wherein
the plurality of kind of band pass filters includes a first kind of band pass filter and a second kind of band pass filter,
a size of the first kind of band pass filter is different from a size of the second kind of band pass filter, and
the plurality of kind of band pass filters is configured to transmit light of different wavelength bands;
a color filter array including a plurality of type of color filters that transmit light of different wavelength bands;
a light receiving unit including a plurality of pixels configured to:
receive modulated light modulated by the coded mask and the color filter array, and
generate 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; and
an image reconstruction processing unit configured to:
reconstruct the observation signal data generated by the light receiving unit, 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,
restore, based on a binary matrix operation process, the first channel data and the second channel data, and
generate image data based on the restored first channel data and the second channel data.
