Imaging apparatus and a camera for vehicles |
摘要 |
A camera apparatus for vehicles including an imaging element and a lens comprises a gradation generation unit for stepwise changing the light amount reaching a whole or part of the imaging element. By this, a gradation region is formed on the imaging element and it absorbs assembling errors during manufacturing and positional shifts attributed to a road surface slope or the like. Even when an inverse light state is caused, it is possible to improve the image processing performance with an ecconomical configuration.
