LIGHT SOURCE TYPE DETERMINABLE COLOR HEADLIGHT TESTER

摘要

PROBLEM TO BE SOLVED: To provide a color headlight tester for testing a headlight by performing color image processing of projection light from the headlight.SOLUTION: Light source type determination means determines a light source type on the basis of RGB data obtained by performing color image processing in a light distribution pattern of projection light from a headlight projected onto an internal screen in a light receiving part. The light source type determination means automatically discriminates whether the headlight is a warm color system lamp (halogen lamp) or a cold color system lamp (HID lamp).SELECTED DRAWING: Figure 7
