Abstract: An IR camera includes: a thermal radiation capturing arrangement for capturing thermal radiation of an imaged view in response to input control unit(s) receiving user inputs from a user of the IR camera; a processing unit arranged to process the thermal radiation data in order for the thermal radiation data to be displayed by an IR camera display as thermal images; and an IR camera display arranged to display thermal images to a user of the IR camera. The processing unit is further arranged to determine at least one temperature reference value representing the temperature of the surrounding environment of the imaged view; and calculate at least one output power value indicative of an amount of energy dissipated in a part of the imaged view by using the temperature value of the thermal radiation data corresponding to said part of the imaged view and the at least one determined temperature reference value.

Abstract: A method for displaying a thermal image in an infrared (IR) thermal camera, includes, for an embodiment, registering an outdoor temperature value, registering an indoor temperature value, calculating an isotherm level by using the registered temperature values and a temperature color alarm level, imaging a surface area to create an image of the temperature distribution in at least a part of the surface area, comparing the surface area temperature in at least one image point of the thermal image to the isotherm level, adjusting the color of the at least one image point in dependence of the relation between the surface area temperature in said at least one image point and the isotherm level and displaying the colored version of the thermal image. The method may allow a user to determine immediately, on-site, if a building is well insulated and may present an easily interpreted and understandable thermal image.

The lens assembly is mounted at one end of the housing, the other end portion of which is formed as a user handle, the longitudinal axis of which preferably is inclined relative to the optical axis of the lens assembly to form an angle (?alpha) with the optical axis. There are provided manual control elements for allowing single hand operation of the camera, and a visual control elements is intended to be viewed when holding and operating the camera away from the eye and the body of a user. The camera is advantageously provided with elements for wireless transmission of information from the camera.

Abstract: An infrared (IR) camera includes a camera unit for recording IR images, a slave monitor connected to the camera unit for displaying IR images recorded by the camera unit. In this way, the camera unit can be moved independently of the operator. The slave monitor is preferably connected to the camera unit via a cable, a short-range radio connection or a Wireless LAN (WLAN) link. The connection is used for communicating image data from the camera unit to the slave monitor as they are recorded. The connection may also be used for control data from the slave monitor to the camera unit.
