Abstract

A vehicular viewing device including a display section that displays an imaging result of a rear imaging section imaging behind a vehicle, and a controller that, when an warning target has been detected in the imaging result, controls the display section such that a predetermined warning image is displayed in a region outside a predetermined field of view required range in a captured image expressed by the imaging result.

Claims

1. A vehicular viewing device comprising:

a display section that displays an imaging result of a rear imaging section imaging behind a vehicle; and

a controller that, when an warning target has been detected in the imaging result, controls the display section such that a predetermined warning image is displayed in a region outside a predetermined field of view required range in a captured image expressed by the imaging result.

2. The vehicular viewing device of claim 1, wherein

the controller controls the display section such that the warning image is displayed in a region further toward an upper side than a horizon line or a vanishing point in the captured image as the region outside the field of view required range.

3. The vehicular viewing device of claim 2, wherein:

when the warning image is displayed in a region at the upper side of the horizon line, the horizon line is found from an attachment position of the rear imaging section; and

when the warning image is displayed in a region at the upper side of the vanishing point, the vanishing point is found from the captured image.

4. The vehicular viewing device of claim 1, wherein:

the controller further controls the display section such that the size of the warning image is changed and displayed according to at least one of a size of the warning target in the captured image, or a distance to the warning target.

5. The vehicular viewing device of claim 1, further comprising a rear imaging section that images behind the vehicle.

6. The vehicular viewing device of claim 1, wherein:

the controller extracts a brightness of the specific region from an imaging result of a surroundings imaging section that images vehicle surroundings including at least a specific region on an extension line between an occupant and the display section, and further controls the display section so as to become a predetermined luminance according to the extracted brightness.

7. The vehicular viewing device of claim 6, further comprising

a surroundings imaging section that images vehicle surroundings including at least a specific region on an extension line between an occupant and the display section.

8. The vehicular viewing device of claim 7, further comprising

a center monitor that generates and displays overhead images centered on the vehicle from images imaged by the surroundings imaging section.
