For example the IR camera in the Galaxy S21 Plus model generates an IR 

image signal that inherently includes temperature information, e.g. hotter 

objects appear brighter in the image, which enables a user to distinguish hot 

objects from colder objects, bare earth from vegetation etc.

The module of the Samsung smartphone generates a signal representative of

the electromagnetic radiation.

For example, the IR camera/sensor generates a signal responsive to the 

infrared electromagnetic radiation received from the location or subject at 

which the IR camera is pointed, or from the vicinity in which the smartphone

location, and

For example, the main processor in the SoC device processes the signal to 

extract information of the infrared electromagnetic radiation, in the location 

of the IR sensor or at which the IR camera is pointed in the case of the IR 

wide angle camera and Iris Scan feature. 

For example the IR sensor in the Galaxy S4 and Note 3 models produces a 

signal that is used by the SoC processor to provide a numeric temperature 

reading to the user via the display.[1]

For example the IR camera in the Galaxy S21 Plus model generates an IR 

image signal that is representative of the infrared electromagnetic radiation 

and provides the image to the user on the display of the smartphone. [2]

For example, the IR camera of the Galaxy S8, S8+, S9, S9+ and Note 8 

models used for the Iris Scan feature generates an image signal responsive 

to the infrared radiation received from the user’s iris. The SoC device 

processes the signal to extract information, based in part on the intensity of 

the received infrared electromagnetic radiation, to determine characteristics 

of the user’s iris. If the characteristics sufficiently match previously recorded 

characteristics, the SoC unlocks the smartphone. [3] [4] [5]

sending said information

to the output means for 

conveying the 

information to the 

operator.

The Samsung smartphone sends the information to the output means for 

conveying the information to the operator.

For example, depending on the feature being activated, the SoC processor 

sends the information to the touchscreen display, which causes the display to

be unlocked as in the case of the Iris Scan feature, or to display a 

temperature, or to display an IR image captured with the IR camera. [1] [2]
