Claim:
1. A process for mapping temperatures in an enclosure during a combustion process, comprising: providing a device setting for an image-capturing device; generating an intensity-temperature mapping by performing an intensity-temperature calibration based on an intensity of an image pixel in a field of view (FOV) generated by the image-capturing device, a corresponding temperature measurement, and the device setting of the image-capturing device; detecting an amount of emitted radiation of selected regions within the enclosure based on a first image in the FOV captured by the image-capturing device at the device setting; determining whether at least one region of said selected regions is poor responsive, which is underexposed or overexposed, such that an accurate temperature is unable to be estimated based on the intensity-temperature mapping associated with the device setting; and replacing, using a computer processor, temperatures of the at least one poor responsive region with temperatures from acceptable regions unaffected by a saturation from at least one other image in the FOV captured at a different device setting in order to provide an extended temperature mapping of the enclosure, wherein the extended temperature mapping has higher temperature resolution and range than that associated with the first image in the FOV.
