In an illumination apparatus arranged on a vehicle, image data of a plurality of pixels of an imaging region in front of the vehicle is created and an image processor calculates a luminance of each of the pixels on the basis of the image data. A controller is configured to calculate an average luminance of each of partial regions of the imaging region on the basis of the luminance of each of the pixels, to determine whether it is necessary to perform luminance adjustment for each of the partial regions, and to perform luminance adjustment for the partial region on the basis of a result of the determination. An illuminating unit having a plurality of light sources illuminates the partial region while allowing each light source to be adjusted so as to have a predetermined light quantity on the basis of the result of the luminance adjustment.
