Abstract
Videokamera sadrži fotoosjetljive senzore pomoću kojih se provodi analiziranje distribucije intenziteta svjetlosti promatrane scene te optoelektričku pretvorbu. Sukladno principima funkcioniranja ljudskog vizualnog sustava i doživljaja boja, fotoosjetljivi senzori videokamere generiraju tri komponente videosignala. Komponente su podešene na pažljivo izabrane valne duljine primarnih boja: crvenu, zelenu i plavu, poznate kao R, G i B komponente. Iako su R, G i B komponente nužne za formiranje slike u boji vidljive ljudskom oku, zbog vrlo visoke zalihosti među njima, nisu pogodne za djelotvornu pohranu i prijenos videosignala za prikaz slike u boji. Oslanjajući se upravo na redundanciju komponenti RGB formata, videosignal se transformira u druge oblike komponentnog videosignala koji mnogo učinkovitije koriste resurse. U radu su obrađene značajke standardnih oblici komponentnog videosignala: RGB, YUV, YIQ i YCBCR. Provedena je programska i opisna analiza pretvorbi formata videosignala uzimajući u obzir vremensko i frekvencijsko područje te primjenu pojedinih oblika komponentnog videosignala.
Abstract (english)
A video camera consists of three photosensitive sensors which analyze the light distribution in the observed scene and then converts the optical signals into electrical signals. According to the principles of the human visual system and the color sensation, photosensitive sensors in a camera generate three components of a video signal. Components are carefully tuned to a chosen wavelenght of primary colors: red, green and blue, known as R, G and B components. Althought they are necessary for forming a color image by a human eye, because of the very high redundancy between these three components, they are inappropriate for video signal processing and transmission. Taking into account high redundancy of RGB format, the video signal is transformed into other forms of component video signals which are much more efficient. In this BSc Thesis there will be described features of standard forms of component video signals: RGB, YUV, YIQ and YCBCR. There will also be given a presentation of the program and a descriptive analysis of the component transformation, considering both the time and frequency domain, but also the applications of individual component video signal forms.
