CALCULATING ENERGY DISSIPATION IN AN IR IMAGE
First Claim
1. An IR camera (1) comprisinga thermal radiation capturing arrangement (4, 5, 6) for capturing thermal radiation of an imaged view (2) in response to an input control unit(s) (12) receiving inputs from a user of the IR camera (1);
- a processing unit (7,) arranged to process the thermal radiation data (Tx,y) in order for the thermal radiation data (Tx,y) to be displayed by an IR camera display (11) as thermal images; and
a IR camera display (11) arranged to display thermal images to a user of the IR camera (1);
characterized in thatthe processing unit (7,) is further arranged to;
determine at least one temperature reference value (Trad,env,Tconv,env) representing the temperature of the surrounding environment of the imaged view (2);
calculate at least one output power value (PDx,y) indicative of an amount of energy dissipated in a part of the imaged view (2) by using the temperature value of the thermal radiation data (Tx,y) corresponding to said part of the imaged view (2) and the at least one determined temperature reference value (Trad,env,Tconv,env).

Abstract
An IR camera comprises: 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 a IR camera display arranged to display thermal images to a user of the IR camera. The IR camera is characterized in that 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.

15. A method for use in a processing unit (7) of an IR camera (1) capturing thermal radiation data (Tx,y) of an imaged view (2), the method being characterized by comprising the steps of:
-
determining at least one temperature reference value (Trad,env,Tconv,env) representing the temperature of the surrounding environment of the imaged view (2); calculating at least one output power value (PDx,y) indicative of an amount of energy dissipated in a part of the imaged view (2) by using the temperature value of the thermal radiation data (Tx,y) corresponding to said part of the imaged view (2) and the at least one determined temperature reference value (Trad,env,Tconv,env). - View Dependent Claims (16, 17, 18, 19, 21)
