1. A vehicle light-adjusting system comprising:
an incident portion which an external light enters;
a light-adjusting member arranged in the incident portion;
a light emitting unit provided in an interior of a vehicle; and
a control unit that controls transmittance of the light-adjusting member and controls illuminance of the light emitting unit, wherein
the light-adjusting member is divided into a plurality of parts, and
the control unit is capable of adjusting an individual transmittance of each of the plurality of parts,
wherein the light emitting unit is arranged remotely from the light-adjusting member,
the vehicle light-adjusting system further comprising an information acquiring unit that acquires information on a predetermined object in the interior,
wherein the control unit, based on the information acquired by the information acquiring unit:
adjusts the transmittance of the light-adjusting member to reduce an amount of external light entering the interior of the vehicle while adjusting the illuminance of the light emitting unit to increase an amount of emission light in the interior of the vehicle to compensate for the reduced amount of external light entering the interior of the vehicle, or
adjusts the transmittance of the light-adjusting member to increase the amount of external light entering the interior of the vehicle while adjusting the illuminance of the light emitting unit to reduce the amount of emission light in the interior of the vehicle to compensate for the increased amount of external light entering the interior of the vehicle,

wherein
the light-adjusting member is divided into the plurality of parts by a plurality of lines arranged along a predetermined direction and a plurality of intersecting lines intersecting the plurality of lines,
the control unit determines a light-shielding part that shields light among the plurality of parts, and a non-light-shielding part that does not shield light among the plurality of parts based on the information acquired by the information acquiring unit, adjusts the transmittance of the light-shielding part to within a first range, and adjusts the transmittance of the non-light-shielding part to within a second range, and
the light-adjusting member is operable to provide adjacent parts as alternately-arranged light-shielding parts and non-light-shielding parts to protect privacy of an occupant.
