Claim:
1. A lighting control device comprising: luminance acquiring circuitry that acquires a luminance measured value of a fixed point of an object which is viewed from a predetermined viewpoint; lighting adjusting circuitry that individually controls a plurality of light sources irradiating the object from different directions based on the luminance measured value, and adjusts lighting on the object for a luminance value of the fixed point to approach a predetermined setting value; and an information storage that stores positional information, the positional information indicating a correspondence relation between positions of a plurality of fixed points and positions of the plurality of light sources, wherein the lighting adjusting circuitry performs a light control processing including at least one of light reduction and light increase based on the positional information, the lighting adjusting circuitry performs the light reduction of reducing luminosity of a light source corresponding to the fixed point when the luminance measured value of the fixed point is higher than the predetermined setting value, and the lighting adjusting circuitry performs the light increase of increasing the luminosity of the light source corresponding to the fixed point when the luminance measured value of the fixed point is lower than the predetermined setting value.
