1. A vehicle lamp system comprising:
an illuminance variable lamp capable of performing adjustment such that illuminance of any region of an angle of view of a vehicle camera mounted on a vehicle is different from illuminance of another region;
an illuminance fixing lamp capable of emitting light with a specific illuminance toward a region including the angle of view of the vehicle camera; and
a lamp controller configured to control the illuminance variable lamp and the illuminance fixing lamp,
wherein the lamp controller is configured to
after acquiring, from a vehicle controller configured to control the vehicle, position information and illuminance of a low accuracy region where a recognition accuracy of the angle of view of the vehicle camera is equal to or less than a predetermined value,
determine whether the illuminance of the low accuracy region is less than a threshold,
control the illuminance variable lamp so as to increase the illuminance of the low accuracy region if the illuminance of the low accuracy region is less than the threshold, and/or
control the illuminance variable lamp so as to decrease the illuminance of the low accuracy region if the illuminance of the low accuracy region is equal to or greater than the threshold,
wherein the illuminance of the low accuracy region is an average value of luminance of pixels belonging to the low accuracy region among the pixels of the vehicle camera, and
wherein the lamp controller is further configured to:
determine whether the illuminance fixing lamp is in a lighting state,
based on a determination that the illuminance of the low accuracy region is less than the threshold and the illuminance fixing lamp is in the lighting state, control the illuminance variable lamp so as to increase the illuminance of the low accuracy region,
based on a determination that the illuminance of the low accuracy region is less than the threshold and the illuminance fixing lamp is not in the lighting state, turn on the illuminance fixing lamp and control the illuminance variable lamp so as to increase the illuminance of the low accuracy region,
based on a determination that the illuminance of the low accuracy region is equal to or greater than the threshold and the illuminance fixing lamp is not in the lighting state, control the illuminance variable lamp so as to decrease the illuminance of the low accuracy region, and
based on a determination that the illuminance of the low accuracy region is equal to or greater than the threshold and the illuminance fixing lamp is in the lighting state, turn off the illuminance fixing lamp and control the illuminance variable lamp so as to decrease the illuminance of the low accuracy region.
