  • Publication number: 20240116427
    Abstract: A drawing processing unit generates multi-gradation light distribution image data that defines a light distribution. The image processing unit executes multiple software processes sequentially. The drawing processing unit self-diagnoses the presence or absence of an abnormality for each software process. The drawing processing unit transmits first diagnostic data that indicates the self-diagnosis results to the auxiliary processor. Furthermore, the drawing processing unit transmits first feedback data based on data generated for each software process to the auxiliary processor. The auxiliary processor diagnoses the presence or absence of an abnormality in the multiple software processes executed by the drawing processing unit based on the first feedback data.
