DISTANCE MEASUREMENT DEVICE

摘要

A distance measurement device (101) is provided with a light source (102), a light source control unit (103), a light reception unit (104) in which pixels (108) are arranged two dimensionally, an exposure control unit (106), and a signal processing unit (107). The light reception unit (104) outputs, to the signal processing unit (107), a signal corresponding to the amount of charge stored in a storage unit (112). The signal processing unit (107) determines that interference is occurring if the ratio of signal levels at each exposure interval of a signal indicating the charge amount of a single pixel (108) and/or the ratio of the signal level of a pixel (108a) of a first pixel group and a pixel (108b) of a second pixel group exceeds a prescribed threshold relating to a determination standard that is based on the difference between the interval for which the read gate (111) of the pixel (108a) of the first pixel group is open and the interval for which the read gate (111) of the pixel (108b) of the second pixel group is open.
