“…This average is that green represents 59 % of reduced light, while red and blue channels make up only 30 % and 11 %, respectively. Once all the pixels have been turned into light, the histogram of light is produced by counting the number of pixels on each brightness -identical to the one produced by histogram for one color [17,18]. From the given histogram we can see that there are three different tops, one for each color.…”

This paper analyzes the effect of front and back light on the Chroma key effect in a virtual TV studio. The model of the system in which the experiment was realized is given. Different intensity of front and back light was used. The analysis of the front light of 200 lux, 800 lux and 1400 lux was done, while the back light changes in the range from 200 to 1400 lux. The characteristics of the analyzed images were clearly determined by their luminance histogram and parameters Mean, Median, and Standard Deviation. Chroma key effect parameters: Color Tolerance, Edge Thin and Edge Feather were used for the analysis. The results that are considered are tabulated and graphically based on the influence of light on the quality of the realization of the Chroma key effect.
