Abstract: Various techniques are provided for a stray light compensation method for an infrared (IR) camera. For example, a stray light compensation method includes: capturing an IR image of a scene by an IR camera, generating a fixed pattern noise estimate FPNestt0 for time t0 using the captured IR image and a stray light model associated with the IR camera, and performing a fixed pattern noise (FPN) compensation of the captured IR image based on said FPNestt0 to obtain a stray light compensated IR image. The fixed pattern noise estimate may be generated through operations in a frequency domain representation of the captured IR image and the stray light model according to one or more embodiments.

Abstract: A method and a system for displaying an infrared (IR) image and/or a related image on a touch screen are provided. For example, a method may include: displaying, on a touch screen, an image of a scene; partitioning the image into a first part and a second part in response to a user indication made on the touch screen; displaying the first part of the image in an IR image mode using an IR image of the scene capture by an IR imaging sensor; and displaying the second part of the image in a non-IR image mode. The non-IR image mode may include a visible light (VL) image mode for displaying a VL image of the scene, or a fusion image mode for displaying a combination of the IR image and the VL image. The partitioning may be adjusted in response to a swipe gesture made on the touch screen.
