Abstract: Various techniques are provided for systems and methods to process images to reduce consumption of an available output dynamic range by the sky in images. For example, according to one or more embodiments of the disclosure, a region or area in images that may correspond to the sky may be identified based on the location of the horizon in the images. A distribution of irradiance levels in the identified sky region may be analyzed to determine a dynamic range attributable to the sky region. A transfer function that compresses the dynamic range attributable to the sky region may be generated and applied so that the sky in the images may be suppressed, thereby advantageously preserving more dynamic range for terrestrial objects and other objects of interest in the images.

Abstract: Various techniques are provided to detect abnormal clock rates in devices such as imaging sensor devices (e.g., infrared and/or visible light imaging devices). In one example, a device may include a clock rate detection circuit that may be readily integrated as part of the device to provide effective detection of an abnormal clock rate. The device may include a ramp generator, a counter, and/or other components which may already be implemented as part of the device. The ramp generator may generate a ramp signal independent of a clock signal provided to the device, while the counter may increment or decrement a count value in response to the clock signal. The device may include a comparator adapted to select the current count value of the counter when the ramp signal reaches a reference signal. A processor of the device may be adapted to determine whether the clock signal is operating in an acceptable frequency range, based on the selected count value.

Abstract: Various techniques are disclosed for smart surveillance camera systems and methods using thermal imaging to intelligently control illumination and monitoring of a surveillance scene. For example, a smart camera system may include a thermal imager, an IR illuminator, a visible light illuminator, a visible/near IR (NIR) light camera, and a processor. The camera system may capture thermal images of the scene using the thermal imager, and analyze the thermal images to detect a presence and an attribute of an object in the scene. In response to the detection, various light sources may be selectively operated to illuminate the object only when needed or desired, with a suitable type of light source, with a suitable beam angle and width, or in otherwise desirable manner. The visible/NIR light camera may also be selectively operated based on the detection to capture or record surveillance images containing objects of interest.

Abstract: A shutter assembly may be provided for an infrared imaging module to selectively block external infrared radiation from reaching infrared sensors of the infrared imaging module. For example, the shutter assembly may comprise a paddle situated external to an optical element (e.g., lens) and adapted to be selectively moved by an actuator to substantially block external infrared radiation from entering the optical element. The shutter assembly may be stacked relative to a housing of the infrared imaging module without excessively increasing the overall profile of the infrared imaging module. A substantially reflective low emissivity interior surface may be provided on the paddle to reflect infrared radiation originating from an infrared sensor assembly of the infrared imaging module back to the infrared sensor assembly.

Abstract: Various techniques are disclosed for providing a wearable apparatus having an integrated infrared imaging module. In one example, a wearable apparatus implemented as a self-contained breathing apparatus (SCBA) may include a shield to protect a user from an external environment, one or more infrared imaging modules, a projector, a processor, and a communication module for projecting a user-viewable thermal image onto a surface of the shield. Such infrared imaging modules may be positioned internal to the SCBA for protection from a hazardous external environment. In another example, a wearable apparatus implemented as a welding mask may include one or more infrared imaging modules, a projector, a processor, and a communication module, so as to project a user-viewable thermal image onto a surface of a shield of the welding mask, while at the same time protecting these components and the welder's face from a harsh welding environment.
