High dynamic range imaging implementation in scene monitoring under bad illumination
Unapređenje kvaliteta slike širenjem dinamičkog opsega u poslednje vreme se intenzivno
koristi. Ovo za posledicu ima prisustvo znatno više detalja na slici, što je jako bitno u većini
primena. Širenje dinamičkog opsega ima svoje granice i one su definisane fizičkim limitima
senzora koji se koristi, tj. ograničenjima njegovog A/D konvertora. Kada je dinamički opseg
scene značajno širi od dinamičkog opsega senzora, mnogi detalji neće biti adekvatno
prikazani na slici. Međutim, ukoliko senzor inherentno podržava široki dinamički opseg,
jasno se može uočiti da je snimljena slika kvalitetnija od one koja se dobija sa standardnog
senzora...Improving image quality by expanding the dynamic range is extensively used recently. This
results in the presence of significantly more details in the picture, which is very important for
most applications. Expanding the dynamic range has its limits, and they are defined by the
physical limits of sensor used, i.e. the limits of its A / D converter. When the dynamic range
of the scene is significantly wider than the dynamic range of the sensor, many details will not
be shown properly in the picture. However, if the sensor inherently supports wide dynamic
range, it can be clearly noticed that the recorded image quality is higher than the one obtained
with the standard sensors..
