A light distribution controller 300A controls a light distribution variable lamp 200 including a plurality of pixels arranged in an array. The processor 312 executes the software program to generate at least one image defining the light distribution of the light distribution variable lamp 200, and writes the image in the volatile memory 322. A monitoring microcontroller 324 detects an abnormality of the processor 312. A hardware logic circuit 314 (i) generates a light distribution image data IMG_LD to be output to the light distribution variable lamp on the basis of at least one image written in the volatile memory 322 in a normal state of the processor 312, and (ii) generates a light distribution image data IMG_LD on the basis of the generated auxiliary image IMG_AUX without depending on the processor 312 in an abnormal state of the processor 312.
