Abstract
A thermal imaging apparatus and a method of improving image quality in a thermal image video sequence imaging a scene, determining one or more of an image detail level, a degree of image motion and/or an image signal level of one or more captured thermal images; determining, based on one or more of the image detail level, the degree of image motion and/or the image signal level, an adapted frame rate for the capturing of one or more subsequent thermal images for the video sequence; capturing one or more subsequent thermal images at the adapted frame rate to improve the image quality in the video sequence.
Claims17
A method of improving image quality in a video sequence of thermal images captured using a thermal imaging system, the method comprising:
- determining one or more of an image detail level and/or an image signal level of one or more captured thermal images, wherein the determining of the image detail level comprises determining an image detail measure, and wherein the determining of the image signal level comprises determining an image signal level measure;
- determining, based on one or more of the determined image detail measure and/or the determined image signal level measure, an adapted frame rate for capturing of one or more subsequent thermal images for the video sequence, wherein the adapted frame rate is adjusted if the image signal level measure is less than a signal threshold;
- and
- capturing the one or more subsequent thermal images at the adapted frame rate to improve the image quality in the video sequence.
A thermal imaging apparatus comprising:
- a thermal imaging system configured to capture one or more thermal images for a video sequence imaging a scene;
- a processor communicatively coupled to the thermal imaging system, the processor being configured to:
- determine one or more of an image detail level and/or an image signal level of one or more captured thermal images, wherein the determining of the image detail level comprises determining an image detail measure, and wherein the determining of the image signal level comprises determining an image signal level measure;
- determine, based on one or more of the determined image detail measure and/or the determined image signal level measure, an adapted frame rate for capturing of one or more subsequent thermal images for the video sequence, wherein the adapted frame rate is adjusted if the image signal level measure is less than a signal threshold;
- and
- capture the one or more subsequent thermal images at the adapted frame rate to improve an image quality in the video sequence.
