Imaging device for measuring distances of elements in an image

摘要

The device (100) has an imager integrated circuit (101) comprising a matrix of pixels (108) for receiving light rays from a scene. Three focusing units e.g. optically transparent units (116a-116c), are provided between the matrix of the pixels and a light ray inlet face of the device. Opaque layers (113) enable passage of the light rays directed toward the group of pixels and passing through one of the focusing units associated with the group of pixels. The opaque layers block the light rays directed toward the group of pixels and passing through the other focusing units.
