4.How to Get High-quality Images
For thermal cameras, the image quality is by no means limited to the resolution. The function of the image
is to record information of target details, colors, temperature OSD, acquisition date, acquisition time, etc.
Different application will have different requirements for imaging, so choosing the right shooting distance,
image mode, color palette, magnification, temperature width, and fill light is also crucial for obtaining
high-quality images.
4.1 Image Mode
The P series thermal cameras can capture infrared images and visible light images at the same time.
Four different images can be displayed on the screen by selecting the image mode function: thermal
imaging, dual-light fusion, picture-in-picture and visible light. Each image mode has a different emphasis
on displaying information for different applications. The details are as follows:
Illustrations
Introduction
1.Thermal imaging: the infrared image records the heat distribution
on the surface of the object, which is not limited by the visible light
environment. It makes up the information blind area of the visible
light image and plays a vital role in night vision and temperature
analysis. In this mode, the +,- icons in the lower left corner of the
main interface can adjust the magnification of the image so as to
achieve the best effect of the target screen ratio.
2.visible and infrared fusion images. The infrared image records
abundant temperature information of the target, but its resolution is
lower than that of the visible image, especially for the tightly packed
target group. Due to the heat transfer effect, the infrared image can
not record the sharp outline details of the target as the visible image
as a result. The dual-light fusion mode combines the advantages of
infrared and visible light, and can record abundant temperature
information and outline details at the same time. Even the infrared
light and visible light can be fused to a certain scale. Operation: in
this mode, the +, - icons in the lower left corner of the main interface
can adjust the fusion ratio.

P Series Pocket Thermal Camera User Manual

3.PIP: visible light and infrared overlay image. Because of the heat
transfer effect, the infrared image can not distinguish the details of
objects closely arranged in one dimension, such as multiple heating
pipes, so it is difficult to identify the pipes. The picture-in-picture
mode can solve this problem very well by overlaying the infrared
image on the visible light image, and the overlaid position can be
adjusted by the dual-light alignment function.
4.Visible Light: full color image in visible light. The light
compensation design can adapt to the low light environment. The
electronic zoom function can be used to capture the details of a
long-distance target. The lower-left +,- icon of the main interface can
adjust the image magnification, so that the target proportion of the
screen can achieve the best results.
4.2 Color Palette
Human eyes can only distinguish twenty gray levels. Although the gray level of collected infrared image
can be up to thousands of gray levels, it is a pity that the human ability to distinguish gray level is limited,
and information loss is dozens of times. However, the human visual sense of color resolution is strong
enough to distinguish thousands of colors. Therefore, the image with color palette is more distinguishable
and detailed than the gray image.
The three image modes of infrared, dual-light fusion and picture-in-picture are related to the temperature.
Different temperatures can show different colors, and it is easier to analyze the image by choosing the
right color palette which includes black heat, white heat, iron red, lava, rainbow, rainbow HC, and black
red. The color palette can be set through the menu .
4.3 Electronic Zoom
The size of the target object in the image is related to the shooting distance. The shorter the distance, the
smaller the object, which will make it impossible to see the details of the object; the shorter the distance,
the larger the object, which will make the image unable to fully accommodate the object; Therefore, the
appropriate screen ratio of the target is also an important factor affecting the image quality. Adjusting the
distance allows the target to be the right size in the image. However, the distance from the target to the
thermal camera will be limited in many cases, such as high-altitude targets. At this time, the electronic
zoom function will become particularly important. In infrared mode and visible light mode, the ratio of

P Series Pocket Thermal Camera User Manual
8
target to screen can be adjusted by electronic zoom function, and the +,- icons in the lower left corner of
the main interface in each mode can adjust the magnification of the image, so that the ratio of target to
screen can achieve the best effect.
4.4 Alignment Distance
For better dual-light image effects, you need to set the alignment distance separately, that is, the
approximate distance from the thermal camera to the object when using dual-light fusion,
picture-in-picture modes. Operation steps: after entering any of the two image modes of dual-light fusion,
and picture-in-picture, the +,- icons appear on the main interface, and the distance parameters can be set.
The distance range is 0.5m-4m, and the adjustment accuracy is 0.5m. When the adjustment is finished,
touch the screen to hide the icon.
4.5 Temperature Scale Adjustment
The temperature range adjustment refers to the adjustment of the upper and lower temperature limits.
The gray value of the image in the thermal image is related to the temperature. If the temperature range is
fixed and cannot be adjusted, the thermal camera cannot adapt to various scenes with changing
temperature. Adjusting the temperature range can change the gray value distribution in the image and
present a better image. The temperature range adjustment of the thermal camera has two types:
automatic and manual:
Temperature
Scale Mode
Introduction
Auto Mode
In automatic mode, the thermal camera continuously adjusts the upper
and lower temperature limits according to the highest temperature and
the lowest temperature in the entire screen, and presents the best
image in real time.
Manual Mode
In manual mode, you can drag the movable temperature scales to
adjust the upper and lower limits of the temperature. The global best
effect of the image in a specific scene may not be able to meet the
demand, so the temperature range is set near a specific target
temperature through the manual temperature range function, thereby
shielding insignificant objects in the image, and making it easier to
focus on the details of the target.
Notes: Only Auto Temperature scale Mode is available for P200.

P Series Pocket Thermal Camera User Manual

4.6 Fill Light
In case of applying visible light mode in dark scenes, fill light is needed to achieve the ideal image effect.
The secondary menu icon or icon in the main menu can set the turn-on and turn-off of fill light, which
can also be used for lighting.
5.Measuring Temperature
Besides capturing high-quality images, the thermal camera also has another characteristic function, that
is, temperature measurement. How to measure temperature accurately? To obtain accurate temperature,
it is not enough to have high-performance detectors and stable hardware components only, correct
methods are also required. The main factors that influence the result of temperature measurement are
emissivity, ambient temperature, distance, temperature measurement range, unit selection, and so on.
Therefore, before using the camera for measuring temperature, be sure to set the temperature
measurement parameters. In addition, in order to obtain accurate temperature efficiently, suitable
temperature measuring tools should be selected for different target objects.
5.1 Set Measuring Parameters
5.1.1 Set Emissivity
Emissivity refers to the ratio of the radiant power of an object to the radiant power of a black body at the
same temperature, which is relative to the reflectivity of the object.At the same target temperature, higher
target emissivity means that the target can radiate a higher proportion of energy. For example, the
emissivity of body skin is 0.98, and the emissivity of printed circuit boards is 0.91. For more information on
emissivity, please refer to the attached common emissivity table or search from other channels. In order to
obtain more accurate measurement results, it is necessary to set the corresponding emissivity according
to the target to be measured before each measurement. For specific operation steps, please refer to
chapter 8.1.
5.1.2 Set Ambient Temperature
The ambient temperature is an important factor that affects the temperature measurement of the thermal
camera. Before measuring the temperature, it’s necessary to set this parameter in advance. For the
specific operation steps, see 8.1 Measurement Parameters.
5.1.3 Set Distance
Infrared rays will be attenuated in the atmosphere. In the process of temperature measurement, the

P Series Pocket Thermal Camera User Manual
10
distance between the target and the thermal camera will have different effects on the measurement
results. The farther the distance, the lower the temperature. In order to ensure the accuracy of the
temperature measurement, the thermal camera will compensate the result according to the distance of
the object. Therefore, be sure to set the appropriate distance before temperature measurement. Refer to
chapter 8.1 for detailed operation steps.
5.1.4 Set Measuring Gear
The temperature measurement range of the camera is -20～550℃. In order to ensure the imaging effect,
the temperature measurement range is divided into -20～150℃and 100～550℃. The user can
independently select different temperature measurement ranges according to the conditions of use. For
specific operation steps, please refer to chapter 8.2.
5.1.5 Set Units
The temperature unit supports three display modes: Celsius, Fahrenheit, and Kelvin. The default distance
unit is meters. For specific operation steps, please refer to chapter 8.9.4.
5.2 Choose Measurement Tools
Different measurement tools should be chosen for different scenarios because choosing a suitable
measurement tool can improve your work efficiency. Click the icon in the main menu, the fan-shaped
