SuperResolution (optional)
SuperResolution is a technology to improve image quality. Each
time an image is recorded, a sequence of images is saved on the
thermal imager and used to calculate a higher-resolution image
with the aid of the PC software (no interpolation). The pixel count
increases by a factor of 4, while the geometric resolution (IFOV) is
improved by a factor of 1.6.
To use the function, the imager must be hand-held (no tripod).
