In the water or atmosphere, front field of view is ensured by a flat front window lens (101) while suppressing abnormality in the refracting power and the stereopsis.

Definition of visibility field for the driver to the line in front of him in relation to the driver's positions.

This display is applicable to a vehicle, a vessel, or an HUD for displaying information in the forward field-of-view.

The display system is preferably contiguous with the forward field of view of the vehicle driver at a focal length that is forward of the vehicle passenger compartment.

As a result, the comfortable interior environment can be maintained, and the field of front vision of the driver can be secured stably and clearly.

If the rear sight is still in the middle of the target where you started, then look where the front sight is.

The width, as seen from a driver, of the front pillar is narrowed while its rigidity is kept, and thereby the width of a forward view field is enlarged and visibility on the far side of the front corner member is improved.

Each pair of imaging components defines a front and rear field of view, with a common overlapping region associated with each respective side of the vehicle support structure.
