Beschreibung
Zusammenfassung:	This malfunction diagnosis apparatus detects a line on a road surface by distinguishing the line from an asphalt surface other than the line. The malfunction diagnosis apparatus sets a first area corresponding to the line and a second area corresponding to the asphalt surface using a first image captured while the line is detected. The malfunction diagnosis apparatus calculates a first brightness in the first area and a second brightness in the second area using a second image captured while the vehicle is cruising and the line is not detected. Further, the malfunction diagnosis apparatus diagnoses the malfunction based on at least one of the first brightness and the second brightness.
