Detailed Explanation of Infrared Thermal Image Palette

Infrared thermal imaging technology can break through the limitations of human vision. The output thermal image is the key to user judgment or decision-making when using infrared thermal imaging cameras. Infrared thermal image shows temperature difference of the radiation of targets. Greater temperature difference means more obvious contrast of thermal image. In order to facilitate users to use it in different scenes, GSTiR infrared camera cores support a variety of pseudo colors such as white hot, black hot, iron red, lava, arctic, medical, rainbow, red tracing, etc. So what is the significance of changing the palette with different colors?

Like visible light digital images, infrared thermal images are also composed of thousands of pixels. Usually when we purchase infrared camera core, GSTiR provides a variety of resolutions such as 120x90, 256x192, 384x288, 640x512, 800x600, 1280x1024, etc. These array specifications represent pixels. For example, a 1280x1024 resolution infrared camera core represents 1.3 million pixels. The higher pixel infrared camera module means that it can output clearer and more detailed infrared thermal images. Each pixel represents a specific temperature data, and these different temperature data are equipped with unique color grayscale values based on different values. When the heat value of target changes, the color gray value of each pixel will change accordingly. These heat palettes determine the appearance color of the pixels. Users can choose appropriate color according to different application scenarios.

In the field of security surveillance, in order to comply with night surveillance viewing habits and present more details, original white-hot images are usually used.

In the field of outdoor night vision, the white-hot palette is also the most common mode. It uses white to display objects with higher temperatures and black to display low-temperature objects. The black-hot palette reverses the white-hot palette to present details with higher temperatures. Temperatures appear in black, and cooler objects appear in white. A favorite among search and rescue personnel and wildlife conservation, the Black Heat Palette displays body heat in a clear and realistic image.

In the field of infrared temperature measurement for power inspections, hot iron palettes are often used, which can display heat distribution and fine details through color to quickly identify thermal anomalies.

Medical palettes are often used in the field of medical testing, such as body temperature monitoring during epidemic prevention and control, etc.

The main feature of the rainbow palette is that its high contrast reflects small temperature differences, which is suitable for application scenarios with small temperature differences and can clearly display subtle temperature differences.
