Patent Images
1. A method of displaying visible-light (VL) images and/or infrared (IR) images, the method comprising:
- providing a camera having a VL camera module, an IR camera module, and a display, the VL camera module having a first field of view (FOV), the IR camera module having a second FOV different from the first FOV causing a parallax error;
focusing the IR camera module on a target to create a focused second FOV;
the focusing of the IR camera module registering at least a portion of the first FOV with the focused second FOV to correct the parallax error; and
displaying an image of the registered first FOV, or the focused second FOV, or a blended image of the registered first FOV and the focused second FOV.

Abstract
Methods and apparatuses of registering on a camera display separate fields of view of a visible light camera module and an infrared camera module by focusing the IR camera module. The fields of view can be displayed in several display modes including 1) full screen visible, infrared and/or blended, 2) picture-in-a-picture such as partial infrared image in a full screen visible image, and 3) infrared color alarms in visible-light images.

6. A method of displaying visible-light (VL) images and/or infrared (IR) images, the method comprising:
-
providing a camera having a VL camera module and an IR camera module and a display, the VL camera module having a first field of view (FOV), the IR camera module having a second FOV different from the first FOV causing a parallax error, the VL camera module producing an image of the first FOV, the IR camera module producing an image of the second FOV; displaying at least portions of the images from the VL camera module and the IR camera module on the display; registering the images from the VL camera module and IR camera module on the display by displacing the images from the VL camera module and the IR camera module relative to each other until registered to correct the parallax error via a manual adjustment mechanism. - View Dependent Claims (7, 8, 9, 10)

11. A camera producing visible and infrared images, the camera comprising:
-
a visible camera module having a VL sensor array of pixels and VL optics; an IR camera module having an IR sensor array of pixels and IR optics, the IR sensor array of pixels having substantially fewer pixels than the VL sensor array of pixels; the VL camera module and the IR camera module being displaced from one another so that the IR and VL camera modules see a target scene from different views causing a parallax error; means for correcting the parallax error; and a display for concurrently displaying images from the IR camera module and the VL camera module such that the images register without parallax error. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A computer-readable medium programmed with instructions for performing a method of registering images from multiple camera modules, the medium comprising instructions for causing a programmable processor to:
-
receive a first image that includes a target from a visible light (VL) camera module, the VL camera module having a first field of view (FOV) and a VL sensor array of pixels for producing the first image; receive a second image that includes the target from an infrared camera (IR) module, the infrared camera module having a second FOV and an IR sensor array of pixels for producing the second image, the IR sensor array of pixels having substantially fewer pixels than the VL sensor array of pixels; determining the distance from at least one of the camera modules to the target; correcting a parallax error using the determined distance; registering the first and second images corrected for parallax error; and displaying at least portions of the first and second images on a display with the portions of the first and second images registered. - View Dependent Claims (19, 20, 21, 22, 23)
