Vehicle display device
A vehicle display device including an image display unit and a control unit is provided. An image includes a both-eye region that is a region visually recognized by both eyes of the driver and a one-eye region that is a region visually recognized by only one eye of the driver. The control unit sets a non-display region at a boundary portion between the both-eye region and the one-eye region and perform control such that at least no static image is displayed in the non-display region.
1 . A vehicle display device comprising:
an image display unit that emits display light for an image;
an optical system that projects the display light emitted from the image display unit toward a reflecting surface in front of a driver; and
a control unit that controls the image display unit, wherein
the image includes a both-eye region that is a region visually recognized by both eyes of the driver and a one-eye region that is a region visually recognized by only one eye of the driver,
the control unit sets a non-display region at a boundary portion between the both-eye region and the one-eye region and controls such that at least no static image is displayed in the non-display region,
the control unit sets a width of the non-display area based on an average amplitude of movement of a head of the driver in a left-right direction, and
the control unit changes the width of the non-display area in proportion to a change in the average amplitude.
2 . The vehicle display device according to claim 1 , wherein
the control unit includes a first acquisition unit that acquires movement of the head of the driver in the left-right direction;
the control unit determines the average amplitude of movement of the head of the driver based on the movement of the head of the driver acquired by the first acquisition unit, and
the control unit includes a first setting unit that sets the width of the non-display region in a horizontal direction based on the average amplitude of movement of the head of the driver.
3 . The vehicle display device according to claim 1 , wherein the control unit includes:
a second acquisition unit that acquires a viewpoint position of the driver; and
