A camera that can capture a visible light image and an infrared image of a target scene. The camera includes a focusable infrared lens and a display. The display provides the visible light and infrared images in a focus mode or an analysis mode. In the focus mode, the percentage of infrared imagery of the target scene is relatively higher to assist the user in focusing the infrared image. In analysis mode, the percentage of infrared imagery is relatively lower to assist the user in analyzing and visualizing the target scene. The modes may be switched manually or automatically.

The invention claimed is: 1. A camera for producing visible-light (VL) images and infrared (IR) images, comprising: VL sensors for sensing VL images of a target scene; IR sensors for sensing IR images of the target scene; focusable optics for capturing the target scene; and a display area for displaying a composite image including at least a portion of the VL images and the IR images superimposed and blended in one of a focus mode and an analysis mode, the modes being particular ratios of the amount of VL images to the IR images in the blended composite image, the analysis mode blend ratio being different from the focus mode ratio and being appropriate for analyzing and visualizing the target scene, the focus mode blend ratio being appropriate for focusing the optics, the analysis mode being the default mode used by the display area, and the display area being switchable between the focus mode and the analysis mode. 2. The camera of claim 1, wherein the focusable optics are optics for the IR sensors. 3. The camera of claim 2, further including optics for the VL sensors, and wherein the VL optics and IR optics have different fields of view so that the VL and IR images of the target scene have a parallax error. 4. The camera of claim 3, wherein focusing the IR optics registers the VL and IR images to correct the parallax error. 5. The camera of claim 4, wherein a detection of focusing the IR optics causes a switch to the focus mode. 6. The camera of claim 1, wherein the analysis mode blend ratio is higher than the focus mode ratio. 7. The camera of claim 6, further including a sensor for detecting a focus change in the focusable optics. 8. The camera of claim 7, wherein the sensor includes a hall effect sensor. 9. The camera of claim 1, wherein the display area is automatically switchable between the focus mode and the analysis mode. 10. The camera of claim 9, wherein the display is automatically switched to the focus mode after detection of a focus change in the focusable optics. 11. The camera of claim 1, wherein the display area is manually switchable between the focus mode and the analysis mode via camera user controls. 12. The camera of claim 1, wherein the analysis mode blend ratio is such that the percentage of IR images in the composite image is 100%. 13. The camera of claim 1, wherein the focus mode blend ratio is such that the percentage of VL images in the composite image is 100%. 14. The camera of claim 1, wherein the percentage of IR images in the composite image in the focus mode varies from about 50% to 100%. 15. The camera of claim 1, wherein the percentage of VL images in the composite image in the focus mode varies from about 0% to 50%. 16. The camera of claim 1, wherein the superimposed and blended VL and IR images are registered together. 17. The camera of claim 1, wherein the VL sensors and the IR sensors each include arrays of sensors. 18. The camera of claim 1, wherein the blending is alpha-blending. 19. The camera of claim 1, wherein the focus mode and analysis mode blend ratios are one of preset, user-defined, the most recent user blend ratio employed by the user. 20. A camera producing visible light (VL) and infrared (IR) images, the camera comprising: a VL camera module having VL optics and adapted for capturing VL images; an IR camera module having IR optics and adapted for capturing IR images; and a display area for displaying a composite image including at least a portion of the VL images and the IR images superimposed and blended in one of first and second modes, the modes being particular ratios of the amount of VL images to IR images in the blended composite image, the first mode blend ratio being different from the second mode ratio and being appropriate for analyzing and visualizing the target scene, the second mode blend ratio being appropriate for registering the VL and IR images on the display, the first mode blend ratio being the default mode used by the display area, and the IR images and VL images translatable on the display relative to one another for registering the IR and VL images on the display, the display area being able to toggle between the first and second modes. 21. The camera of claim 20, wherein the first and second modes are analysis and focus modes, respectively. 22. The camera of claim 20, wherein the IR optics are focusable. 23. The camera of claim 22, wherein focusing the IR optics translates the IR images relative to the VL images. 24. The camera of claim 23, wherein a detection of focusing the IR optics causes a switch to the second mode. 25. The camera of claim 20, wherein actuation of a camera control mechanism translates the IR images. 26. The camera of claim 20, wherein actuation of the camera control causes a switch to the second mode. 27. The camera of claim 20, wherein the VL optics and the IR optics have separate fields of view so that the VL and IR images of a target scene have a parallax error. 28. The camera of claim 27, wherein the translation of the IR images corrects the parallax error. 29. A camera with a computer-readable medium programmed with instructions for performing a method of operating a camera display, the camera display for displaying a composite image of visible light (VL) and infrared (IR) images of a target scene superimposed and blended, the medium comprising instructions for causing a programmable processor to: detect a change in a camera parameter indicative of a desire to display the composite image with a first ratio of the amount of IR images to the VL images in the blended composite image; display the composite image with the first ratio; determine a lack of change in the camera parameter for a period of time; and change the ratio of the composite image display to a second ratio after determining the lack of change. 30. The camera of claim 29, further comprising instructions to initially set the camera display to the first ratio. 31.
