Embodiment Construction

[0034] Disclosed herein are systems and methods that provide enhanced visual representation and display of infrared data values ​​in accordance with various embodiments. For example, an infrared camera can be used to capture thermal images. These thermal images can be processed by performing a mapping process using an improved palette (or LUT) according to various embodiments of the present disclosure to create and display visual representations that advantageously have better distinguishable temperature range changes.

[0035] Hereinafter, the terms "visual representation of infrared data values", "visual representation" and "infrared image" are used interchangeably.

[0036] For ease of understanding, the method embodiments herein are typically described with respect to a single frame of infrared data values; however, these methods can be applied to any number of captured frames of infrared data values ​​and can be used to generate still images and / or video image sequences. ...

Abstract

Imaging systems and methods are disclosed for generating enhanced visual representations of captured data such as infrared image data. For example, the perceived color distance or contrast between colors representing adjacent output levels (e.g., temperature or infrared intensity levels) are enhanced in visual representations of infrared images. According to embodiments, infrared image data valuesrepresenting a scene may be mapped according to a color palette implemented using complementary colors as adjacent (e.g., successive) base colors or a sequence of colors that repeats a predetermine set of hues with varying saturation and/or intensity, thereby increasing the color contrast between pixels representing subtle temperature differences in the scene. The color palette can be enlarged bymapping a larger number of distinct output levels to a larger sequence of colors, for example by increasing the bit-depth of the color palette, such that color transitions look smoother and more natural.
