Abstract
A digital camera has a lens, a camera housing, and a semiconductor sensor. The camera housing is primarily formed of a transparent plastic block that encloses a semiconductor sensor only on its underside and has an adapted lens on its top side. Between the two there is provided an opaque layer with an aperture that improves the image quality. The invention also relates to a method for producing such a digital camera.
Claims24
A digital camera, comprising:
- a lens having a lens top side and a lens underside;
- a camera housing;
- a light-sensitive semiconductor sensor having a top side aligned with said lens and an underside;
- said camera housing having a plastic body with a top side carrying said lens and an underside with said light-sensitive sensor;
- a transparent plastic core filling an interspace between said lens underside and said top side of said semiconductor sensor, wherein the entire space between said lens underside and said top side of said semiconductor sensor is filled by said transparent plastic core;
- and
- wherein a circular aperture is formed between said lens underside and said top side of said semiconductor sensor in said transparent plastic core.
