A building system, such as an elevator system, a physical access control system, or a combined elevator and physical access control system, has a controller system to control the building system to perform a building action, and a credential acquisition unit to acquire a credential presented by a user. The building system includes a camera system having a thermographic camera, which generates an infrared image of a face of the user, and an image processing system. The image processing system processes the infrared image to determine if the user's face shows a temperature value that is higher than a set threshold temperature value. The controller system enables or disables the building action as a function of the acquired user credential and the result signal.

An image based correction system compensates for the image quality artifacts induced by thermal ghosting on evolving imaging member surfaces. With thermal ghosting directly tied to previous image content, a feed forward system determines thermal ghosting artifacts based on images previously rendered and generates an open loop gray-level correction to a current image that mitigates undesirable ghosting. For example, the correction system compensates for the thermal ghosting by making the current image “lighter” in areas that will be imaged onto warmer blanket regions, thereby cancelling out TRC differences between different temperature regions. A temperature sensor is used to measure the temperature of the imaging blanket due to the stresses induced by the image. This data is used to learn the parameters of the temperature model periodically during operation, and used in subsequent corrections to mitigate thermal ghosting in spite of changes in blanket properties over use and time.

A notification control device for controlling notification based on subject information is disclosed. The subject information including temperature image data, which indicates temperature of a subject captured within a predetermined capturing range, is received. A predetermined destination of notification information, which represents a state of the subject based on the subject information, is notified. A process of notifying the notification information to the predetermined destination is stopped depending on whether or not the subject information includes predetermined identification information.

A thermal imaging system for a cooking appliance is capable of being calibrated for any arrangement of cooktop burners disposed on a surface of a cooking appliance. A thermal imaging system can be calibrated by processing a received thermal scan of a surface of a cooking appliance having a particular cooktop arrangement to identify a plurality of cooktop burners on the surface of the cooking appliance for the particular arrangement, determine a number of cooktop burners in the particular arrangement, and determine one or more locations of the cooktop to assign to each of the cooktop burners. Further, the determined one or more locations assigned to each of the cooktop burners can be stored in association with a respective cooktop burner. Once calibrated, the thermal imaging system can calculate a temperature for each of the cooktop burners to be used in performing subsequent control and/or safety functions.
