Claim:
1. A thermal imaging device comprising: a housing including a handle portion, wherein a removable and rechargeable battery pack is configured to be inserted into the handle portion for providing power to the thermal imaging device, wherein the battery pack includes a battery pack housing, at least one battery cell positioned within the battery pack housing, a terminal, and a latch mechanism, and, when the battery pack is coupled to the thermal imaging device, the latch mechanism engages the housing of the thermal imaging device to secure the battery back to the thermal imaging device such that a portion of the battery pack housing remains exposed; a visual camera configured to generate a first signal related to a visual image; an infrared sensor configured to generate a second signal related to a thermal image; a display configured to display the visual image based on the first signal and the thermal image based on the second signal; and a controller electrically connected to the visual camera, the infrared sensor, the display, and the inserted battery pack, the controller configured to receive the first signal, the second signal, a feedback control signal, and a calibration signal, the controller further configured to control the display based on the first signal, the second signal, the feedback control signal, and the calibration signal; wherein the feedback control signal is related to at least one selected from the group consisting of an amount of light detected by the visual camera, an amount of thermal radiation detected by the infrared sensor, an ambient temperature, and an average ambient temperature; wherein the calibration signal is related to one or more operational parameters, the operational parameters including at least one selected from the group consisting of the ambient temperature, a rate of change of the ambient temperature, and an operating temperature of the thermal imaging device; and wherein the controller includes a memory configured to store the visual image and the thermal image, the memory further configured to store a set of temperature data associated with the thermal image, the set of temperature data being appended to the visual image, and the visual image, including the appended set of temperature data, and the thermal image being stored separately in the memory.
