Camera system using interchangeable fixed lenses
A camera system is disclosed. The camera system includes a camera that employs interchangeable fixed lenses. By replacing one lens cap with another lens cap, the field of view can be changed since each lens cap has a different fixed lens. The camera can also record images or video in a forward and a backward direction at the same time.
1. A camera, comprising:
a housing including an image sensor; and
a plurality of lens caps, each lens cap including a different fixed lens,
wherein one of the lens caps is mounted on the housing for a first field of view,
wherein the one lens cap can be replaced with another lens cap for a second field of view, and
wherein the housing includes an internal lens.
2. The camera of claim 1 , wherein the internal lens and the image sensor are used to receive one or more images.
3. The camera of claim 1 , wherein the lens cap includes an internal lens.
4. The camera of claim 1 , wherein one or both of the housing and the lens caps are sealed so that water or dust cannot get inside.
5. The camera of claim 1 , wherein the housing is sealed to be waterproof, and wherein the lens cap is sealed to be waterproof.
6. The camera of claim 1 , wherein the housing is sealed to be waterproof with and without the lens cap.
7. The camera of claim 1 , wherein the housing is configured to operate as a camera with and without the lens cap.
8. The camera of claim 1 , wherein the camera is mounted on a weapon.
9. The camera of claim 1 , wherein the one lens cap can be replaced with the other lens cap for the second field of view while maintaining focus on a target.
10. The camera of claim 2 , wherein the one or more images are used for pictures or videos.
11. The camera of claim 3 , wherein the lens cap and the image sensor are used to receive one or more images.
12. The camera of claim 11 , wherein the one or more images are used for pictures or videos.
13. A camera, comprising:
a housing including an image sensor; and
a plurality of lens caps, each lens cap including a different fixed lens,
wherein one of the lens caps is mounted on the housing for a first field of view,
wherein the one lens cap can be replaced with another lens cap for a second field of view,
wherein the housing includes an internal lens, and
wherein a preset distance between a fixed lens of the one lens cap when the one lens cap is mounted on the housing is different from a preset distance between a different fixed lens of the other lens cap when the other lens cap is mounted on the housing instead of the one lens cap.
14. The camera of claim 13 , wherein a focus on a target is maintained even though the one lens cap is replaced by the other lens cap with a different fixed lens and a different field of view.
15. A camera, comprising:
a housing including an image sensor; and
a plurality of lens caps, each lens cap including a different fixed lens,
wherein one of the lens caps is mounted on the housing for a first field of view,
wherein the one lens cap can be replaced with another lens cap for a second field of view,
wherein the housing includes an internal lens,
wherein a preset distance between a fixed lens of the one lens cap when the one lens cap is mounted on the housing is different from a preset distance between a different fixed lens of the other lens cap when the other lens cap is mounted on the housing instead of the one lens cap, and
wherein the focus on a target is maintained even after the replacing the one lens cap with the other lens cap.
