1. An image processing method in an imaging system,
the imaging system comprising: one or more imaging apparatuses connected to a network; and a controller apparatus,
the imaging apparatus comprising:
two imaging elements each comprising multiple pixels arranged in an area for receiving light;
two single filters provided to the two imaging elements, respectively, each configured to have at least a characteristic of transmitting a visible light wavelength region, a characteristic of blocking a first light wavelength region, except for a second light wavelength region, of a longer wavelength side than the visible light wavelength region, and a characteristic of transmitting the second light wavelength region which is part of the first light wavelength region, each of the two single filters being configured to filter light incident on an entirety of the area of corresponding one of the two imaging elements based on the characteristics;
the imaging method comprising:
in the imaging apparatus,
in each of two signal processors, processing a signal obtained by photographing the light that has passed through corresponding one of the two single filters with corresponding one of the two imaging elements and outputting a visible light signal and a signal corresponding to the second light wavelength region;
calculating a distance to a subject by using the two visible light signals or the two signals corresponding to the second light wavelength region;
adding second data to first data or multiplying the first data by the second data to transmit the added or multiplied first and second data outside, the first data being based on the two visible light signals, the second data being based on a distance image generated by calculating the distance; and
in the controller apparatus,
performing face authentication that uses three-dimensional information by using the first and second data.
