Abstract
Maģistra darbs ir uzrakstīts latviešu valodā, datorsalikumāuz 48 lapaspusēm. Tas satur 38 attēlus, 4 tabulas, 18 atsauces uz literatūras avotiem.
Darba mērķis: novērtēt noguruma ietekmi uz datorā stimulēta apmiglojuma uztveres sliekšņiem (tikko pamanāmais apmiglojums, skaidra attēla uztveres slieksnis).
Metodika: apmiglojuma radīšanai tika izmantota avotu metode, lai noteiktu datorā stimulēta apmiglojuma adaptācijas ietekmi uz apmiglojuma uztveres sliekšņiem.
Secinājumi: tikko pamanāmais apmiglojums, tiek konstatēts pie mazāka apmiglojuma filtra diametra, nekā, tad ja optotipa apmiglojuma līmenis tika pakāpeniski samazināts līdz skaidram attēlam.
Atslēgas vārdi: apmiglojums, apmiglojuma adaptācija, apmiglojuma uztvere.
Master thesis written on 48 pages by computer in Latvian. It contains 38 figures, 4 tables, 18 references of literature sources. Aim:to evaluate effect of visual fatigue on computer stimulated blur perception ( Just Noticeable Blurriness and clear image perception threshold). Methods:defocus was generated using source method to evaluate effect of blur adaptation on blur perception thresholds. Conclusions:Just Noticeable Blurriness (JNB) it is found to lower blur filter tham blur level was gradually reduced to clear image. Key words: defocuss, blur adaptation, blur perception.
