Abstract
A scanning module for scanning a document is provided. The scanning module comprises: a chassis; a light source on the chassis for emitting a light ray onto the document; a plurality of reflectors inside the chassis; a lens inside the chassis; an image sensing device inside the chassis, an image of the document being reflected by the plurality of reflectors and formed on the image sensing device, the image sensing device including a plurality of sensing cells; and a plurality of microlenses on the plurality of sensing cells, each of the plurality of microlenses having a top surface and a bottom surface, the top surface having a plurality of notches as an input window for changing an incident angle of the light ray, the bottom surface having a plurality of round curves as an output window for further focusing the light ray.

An image capturing device for capturing a light ray, comprising:
- a lens having a light axis;
- an image sensing device on said light axis, said light ray being focused by said lens to be projected onto said image sensing device, said image sensing device including a plurality of sensing cells;
- and
- a plurality of microlenses on said plurality of sensing cells, wherein at least one of said plurality of microlenses has a top surface and a bottom surface, said top surface having one or more notches as an input window for changing an incident angle of said light ray, said bottom surface having one or more round curves as an output window for further focusing said light ray.
