Imaging apparatus, imaging system that includes imaging apparatus, electron mirror system that includes imaging apparatus, and ranging apparatus that includes imaging apparatus

An imaging apparatus, comprising:

• a lens optical system;
• a color image sensor that includes at least
• a plurality of first pixels on which light that has passed through the lens optical system is incident, and
• a plurality of second pixels on which light that has passed through the lens optical system is incident;
• and
• a first optical element array disposed between the lens optical system and the color image sensor, wherein:
• the lens optical system includes a plurality of optical regions,
• the plurality of optical regions include a first optical region and a second optical region, the first and second optical regions differ in terms of at least one selected from the group of spectral transmittance characteristics and transmissive polarization characteristics,
• the plurality of first pixels include respective spectral filters, the spectral filters having mutually different spectral transmittance characteristics,
• the plurality of second pixels include respective spectral filters, the spectral filters having at least one type of spectral transmittance characteristics,
• the first optical element array directs light that has passed through the first optical region to the plurality of first pixels and directs light that has passed through the second optical region to the plurality of second pixels,
• the first optical element array is a first lenticular lens,
• the first lenticular lens is provided on the color image sensor,
• the plurality of first pixels include:
• spectral filters each having a spectral transmittance characteristic of red;
• spectral filters each having a spectral transmittance characteristic of green;
• and
• spectral filters each having a spectral transmittance characteristic of blue,
• the plurality of second pixels include spectral filters each having a spectral transmittance characteristic of one of red, green, and blue,
• the plurality of first pixels are arranged in first rows,
• the plurality of second pixels are arranged in second rows, and
• second pixels in one of the second rows include more spectral filters each having the spectral transmittance characteristic of the same color as the spectral transmittance characteristic of one of the spectral filters included in first pixels in one of the first rows than the first pixels in the one of the first rows.
