Abstract
Official abstract text for this publication.
A headlight control apparatus (1) for performing control on a headlight device (7) which includes a pair of headlight units (3, 5) each including a light source (9) and an image forming section (16R, 16G, 16B) capable of forming an image and disposed in a light path of light from the light source to illuminate light (101, 105) for projecting the image onto a road surface, wherein the headlight control apparatus forms the image in the image forming section such that a first image (103) projected onto the road surface by one of the headlight units includes a second image (107) projected onto the road surface by the other headlight unit.
First claim
Opening claim text (preview).
The invention claimed is: 1. A headlight control apparatus for performing control of a headlight device which includes a pair of headlight units each including a light source and an image forming section capable of forming an image and disposed in a light path of light from the light source to illuminate light for projecting the image onto a road surface, wherein the headlight control apparatus forms the image in the image forming section such that a first image projected onto the road surface by one of the headlight units encloses thereinside a second image projected onto the road surface by the other headlight unit to thereby cause a boundary line separating between an inside and an outside of the first image and a boundary line separating between an inside and an outside of the second image not to cross each other. 2. The headlight control apparatus according to claim 1 , wherein the first image has a shape similar to the second image, and is larger than the second image. 3. The headlight control apparatus according to claim 1 , wherein the first image has a shape different from the second image. 4. The headlight control apparatus according to claim 1 , wherein insides of the first image and the second image projected onto the road surface are lower in brightness than outsides thereof.
