Summary: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 【課題】ヘッドライトからの投射光をカラー画像処理してヘッドライトのテストを行うカラーヘッドライトテスターを提供する。【解決手段】受光部内の内部スクリーン上に投射されたヘッドライトからの投射光の配光パターンにおいてカラー画像処理を行って得られるRGBデータに基づいて光源種別を判定する光源種別判定手段でそのヘッドライトが暖色系ランプ(ハロゲンランプ)であるか又は寒色系ランプ(HIDランプ)であるかの判別を自動的に行う。【選択図】図7
