Abstract: A method and a device to provide a full representation of an object having a wide dynamic intensive range and maintain a good sensitivity for signal levels throughout the whole intensive range is disclosed. The wide intensive range is divided into a predetermined number of intensive intervals inside the wide intensive range. The intensive intervals are provided at the side of each other or are partly overlapping. The same number of interval representations of the object are provided as the predetermined number of intervals. Each interval representation is adapted to one individual of the intervals. The sizes, acquisition parameters and/or calibration parameters of the interval representations are adapted to each other. The interval representations are combined such that their respective intervals are provided in the same full representation.

Abstract: A device is part of an optical system (1) that works with an intermediate image and comprises stop(5) with associated aperture (6). The device comprises a light-reducing or light-absorbing arrangement (12) located at the side of the aperture. The arrangement is arranged to reduce considerably or eliminate completely light (11) incident to the side of the aperture, and thereby considerably reduce beam reflections. In this way, there is less likelihood of the optical system being detected when this is in use.

The camera is advantageously provided with elements for wireless transmission of information from the camera.

Abstract: An IR camera and a DV processing unit are disclosed which enable a user to use a standard DV recorder to record an IR film sequence and be able to play it back at a later time, and edit it, without using dedicated software. At the same time, the user has access to calibration data, enabling him the selection of data and processing of the film using dedicated software. This is achieved by including additional data related to the image processing in the signal, preferably in the part of the signal normally reserved for audio information.

The invention among others comprises a focus function to be used by a search operation in order to control a moving means (50) adjusting a focusing optical convergence arrangement (20).

Abstract: An optical device includes an objective and a detector or reticle interacting with the objective via a stop aperture. A decentralizing function for the objective and stop relative to the detector or the reticle is arranged to prevent beams reflected byte surface or surfaces of the detector or reticle from passing back through the stop aperture. By preventing reflection of such beams, little or no reflectance is emitted from the device, thereby making detection of the device more difficult.
