Method and apparatus for providing an infrared image
First Claim
1. A method 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, characterized by the following steps:
- a) divide the wide intensive range into a predetermined number of intensive intervals(INT1 to INT3) inside the wide intensive range, which intensive intervals are provided at the side of each other or are partly overlapping;
b) providing the same number of interval representations(IM1 to IMn;
F1 to Fn;
T1 to Tn) of the object as the predetermined number of intervals, each interval representation being adapted to one individual of the intervals;
c) adapting the sizes, acquisition parameters or calibration parameters of the interval representations(IM1 to IMn;
F1 to Fn;
T1 to Tn) to each other;
d) combining the interval representations such that their respective intervals are provided in the same full representation (18;
18′
;
20),e) providing the interval representations for the predetermined number of intervals successively; and
f) adjusting (18;
25) the frame speed of the full representation with the number of successive interval representations in a cycle with different integration times for the successive interval representations, such that the display rate for the combined interval representations has a predetermined frame rate.

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.
