Abstract
(EN)
This image capturing module is provided with an image capturing element, a light emitting element, and a case for holding the image capturing element and the light emitting element. The case has: a light projection aperture that is open toward the front of the case; and a light accommodation unit disposed behind the light projection aperture to accommodate the light emitting element, wherein the light accommodation unit and the light projection aperture are connected to each other inside the case, and the rear end of the light projection aperture is open toward a light emitting surface of the light emitting element. The opening area of the rear end of the light projection aperture is less than the area of the light emitting surface of the light emitting element.

La présente invention porte sur un module de capture d'image qui est pourvu d'un élément de capture d'image, d'un élément électroluminescent, et d'un boîtier destiné à contenir l'élément de capture d'image et l'élément électroluminescent. Le boîtier comprend : une ouverture de projection de lumière qui est ouverte vers l'avant du boîtier ; et une unité de réception de lumière placée derrière l'ouverture de projection de lumière de façon à recevoir l'élément électroluminescent, l'unité de réception de lumière et l'ouverture de projection de lumière étant reliées l'une à l'autre dans le boîtier, et l'extrémité arrière de l'ouverture de projection de lumière étant ouverte vers une surface électroluminescente de l'élément électroluminescent. La zone d'ouverture de l'extrémité arrière de l'ouverture de projection de lumière est inférieure à la zone de la surface électroluminescente de l'élément électroluminescent.
