Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of camera equipment, in particular to a brightness-adaptive image frame-filling thermal imaging camera. Background Art

[0003] Thermal imaging cameras (night vision cameras), as a type of camera, illuminate their surroundings by emitting infrared light (invisible light) and then receiving the reflected infrared light to form an image. However, existing thermal imaging cameras have the following problems: 1. Although image clarity has been significantly improved in low-light environments, image noise, blur, and insufficient resolution are still difficult to avoid; 2. Night vision cameras are significantly affected by temperature, such as unstable performance at high temperatures; 3. High-quality night vision cameras are generally expensive, limiting their widespread adoption. Utility Model Content
