SYSTEMS AND METHODS FOR ENHANCED DYNAMIC RANGE INFRARED IMAGING

摘要

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.
