categories were mapped to the pre‐2010 "thin" category, whereas the "overweight" and "markedly obese" categories were mapped to the pre‐2010 "heavy" category. In addition, the records database contains weight‐related diagnoses, which veterinarians can use when classifying the nature of any consultation. The use of these diagnoses was also examined, and if it did not agree with the body condition assessment (eg, dog assigned a normal body condition, but given a diagnosis of "thin"), the body condition assessment was altered to bring it in line with the stated diagnosis.

One further issue for pre‐2013 data was that the body condition field defaulted to "normal" if a body condition category was not entered. An extrapolation process was used to correct errors arising from this issue, where a non‐default body condition assessmenta light illumination area set for the detected target object. For example, when an oncoming vehicle is detected in the high-beam state (the state in which the headlights of the vehicle on which the vehicular headlight apparatus is mounted are in the high-beam state) or the intermediate-beam state (the state in which the headlights are between the high-beam state and the low-beam state), the vehicular headlight apparatus changes the present light distribution pattern so that the present light illumination area excluding an area near the detected vehicle is illuminated. This makes it possible to illuminate to a sufficient distance without dazzling the driver of the oncoming or preceding vehicle.
In the above vehicular headlight apparatus, the light illumination area is changed depending on the position of an oncoming vehicle.
