To provide a method of adjusting a vehicle display device that can efficiently adjust positional displacement due to a tilt of an image.SOLUTION: A method of adjusting a vehicle display device includes the steps of: performing first inspection, calculating a first correction value, and writing the first correction value into a non-volatile memory 6 of the vehicle display device; and performing second inspection, calculating a second correction value, and writing the second correction value into the non-volatile memory of the vehicle display device. Each of the first correction value and the second correction value is a value with which an image display area is corrected so that a tilt of an axis of an image is reduced, the first correction value is calculated on the basis of a displacement amount according to a tilt of an axis of the image when the image is projected onto a windshield for inspection, and the second correction value is calculated on the basis of a displacement amount according to a tilt of an axis of the image when the image is projected onto a windshield 110 of a vehicle 100. In the second inspection, a display device 3 displays the image in the image display area corrected with the first correction value.SELECTED DRAWING: Figure 8
【課題】画像の傾斜による位置ずれを効率よく調整できる車両用表示装置の調整方法を提供する。【解決手段】車両用表示装置の調整方法は、第一の検査を行なって第一補正値を算出し、第一補正値を車両用表示装置の不揮発性メモリ6に書き込む工程と、第二の検査を行なって第二補正値を算出し、第二補正値を車両用表示装置の不揮発性メモリに書き込む工程と、を含み、第一補正値および第二補正値は、画像の軸の傾斜を低減させるように画像表示領域を補正させる値であり、第一補正値は、検査用のウインドシールドへ画像を投影したときの画像の軸の傾斜に応じたずれ量に基づいて算出され、第二補正値は、車両100のウインドシールド110へ画像を投影したときの画像の軸の傾斜に応じたずれ量に基づいて算出され、第二の検査において、表示デバイス3は、第一補正値によって補正された画像表示領域に画像を表示する。【選択図】図8
