Aim : At daily clinical diagnostic tests, as it is very important to judge whose each specimen it is, we
can think that it is good to photograph faces in order to discriminate individuals of test subjects. I
investigated the changes by making facial portraits by a CCD Camera, by discriminating individuals and
by including simple photographing systems in personal-computers to determine whether individual
discrimination of judged specimens succeeds to be practicable.
Materials and Methods : I performed by joining CCD Camera with personal-computers, through
softwares to take in portraits, by adjusting shades of portraits to signals, by dividing into two kinds, by
letting indicate that shadowy directions were “1” and light directions were “0”, by forming a line of both
0 and 1 and by including systems that let express facial portraits by both 0 and 1 in personal-computers.
Results : As a result of expressing man’s facial portraits by shades of both 0 and 1, man’s facial portraits
formed a line of shades of both 0 and 1 and at both the same man and position, in comparing the first
time with the second time, coincided almost closely. But when the photographing position changed,
somewhat slipped out rows of both 0 and 1. And when the man also changed, somewhat slipped out
rows of that.
Conclusions : By using CCD Camera, individual discrimination by facial portraits seems to be well
practicable. Therefore, by also using cellular phones, individual discrimination seems to be well
practicable. At clinical diagnostic tests, if we introduce these CCD cameras, individual discrimination of
specimens seems to be effectively practicable by using that of this facial portrait.
