Abstract

Various techniques are provided for using one or more thermal infrared (IR) imaging modules to enhance the dynamic range of images. In one example, devices and methods provide a first IR imaging module that captures a first image, a second IR imaging module optimized for higher IR irradiance that captures a second image, and a processing system that detects saturated pixels of the first image, determines pixels of the second image corresponding to the saturated pixels of the first image, and generates a combined image based on non-saturated pixels of the first image and the pixels of the second image. The IR imaging modules may be a microbolometer focal plane array (FPA) configured for high-gain, and a microbolometer FPA configured for low-gain. The IR imaging modules may be a photon detector FPA and a microbolometer FPA.
