Abstract

Camera system for a vehicle comprising an objective lens; a first printed circuit board provided with an image sensor for acquiring image information via the objective lens; and at least one additional printed circuit board adapted for providing a predetermined basic function for the camera system, wherein the first printed circuit board and each of the at least one additional printed circuit board comprises at least a connection unit, wherein the printed circuit boards are electrically connectable in a modular exchangeable manner, respectively, via the at least one connection unit for adapting the range of functions of the camera system according to the predetermined basic function.

First claim

What is claimed is:

1. A camera system for a vehicle, comprising
an objective lens;
a first printed circuit board provided with an image sensor for acquiring image information obtained via the objective lens; and
an additional printed circuit board adapted for providing a predetermined basic function for the camera system;
wherein at least one further additional printed circuit board is provided between the first printed circuit board and the additional printed circuit board and is adapted for providing a predetermined camera specific basic function for the camera system; and
wherein each of the printed circuit boards comprises at least one connection unit adapted for electrically connecting the printed circuit boards to each other in a modular exchangeable manner for adapting the range of functions of the camera system according to the predetermined camera specific basic function,
wherein each of the connection units comprises a plurality of groups of electrical connections, wherein the first printed circuit board is connectable with both of the at least one additional printed circuit board and the additional printed circuit board via the plurality of groups of electrical connections for providing the predetermined camera specific basic function for the camera system; and
wherein a respective group of electrical connections comprises a plurality of electrical terminals located at predefined positions and required for a basic function for operating each of the at least one further additional printed circuit boards, for providing the predetermined camera specific basic function, wherein the respective connection units of the first printed circuit board, at least one further additional printed circuit board and the additional printed circuit board are arranged at predetermined positions geometrically compatible to each other on at least a surface side of the first printed circuit board, the least one further additional printed circuit board and the additional printed circuit hoard.

2. The camera system according to claim 1 , wherein the printed circuit boards are connectable to each other via a plurality of electrical terminals.

3. The camera system according to claim 1 , wherein the electrical terminals of a respective group of electrical connections are located at predefined positions.

4. The camera system according to claim 1 , wherein plural connection units are provided for each printed circuit board.

5. The camera system according to claim 1 , wherein the at least one additional printed circuit board comprises an electrical connection for transmitting data and/or a signal to the exterior of the camera system.

6. The camera system according to claim 1 , wherein the at least one additional printed circuit board is arranged on a side of the first printed circuit board, which is opposite to the side of the objective lens.

7. The camera system according to claim 6 , wherein a plurality of additional printed circuit boards are arranged one after another with respect to the first printed circuit board.

8. The camera system according to claim 1 , wherein the at least one additional printed circuit boards comprises at least one electrical component adapted for providing the predetermined additional function for expanding the camera system.

9. The camera system according to claim 1 , wherein the predetermined additional function for expanding the camera system is at least one of signal acquisition, signal processing, signal transmission, power supply and control function.

10. The camera system according to claim 1 , wherein the at least one connection unit of the printed circuit boards is a plug connection for electrically connecting the printed circuit boards to each other via the electrical terminals of the groups of electrical connections.
