Abstract

Izgudrojums attiecas uz gaismas signāla kodēšanas un dekodēšanas ierīci un īpaši ar RGB krāsu signāla gaismas signāla kodēšanas un dekodēšanas metodi.Gaismas signāla kodēšanas ierīce (1) ietver gaismas signālu ģenerējošu ierīci (5), kas ir konfigurēta, lai ģenerētu un nosūtītu vismaz divu dažādu viļņu garumu gaismas signālu. Gaismas signāla dekodēšanas ierīce (1) ietver sensoru (2), kas ir konfigurēts, lai notvertu vismaz divu dažādu viļņu garumu gaismas signālu un dekodētu minēto signālu, procesoru un atmiņu. Gaismas signāla kodēšanas metode ietver vismaz divu dažādu viļņu garumu gaismas signālu, kuri reprezentē kodētos bitus, ģenerēšanu. Gaismas signāla dekodēšanas metode ietver vismaz divu dažādu viļņu garumu gaismas signālu notveršanu un pārveidošanu par informācijas bitiem, izmantojot apmācītu MNT (Mākslīgais Neirona tīkls) modeli.
