    PC running the application should be set to the IP address of the same subnet 192.168.1.X (e.g. 192.168.1.5) as DVK-300HD. 2. If you are working with multiple DVK-300HD devices, it is possible to connect each device with a network cable to the router. In this setup, the PC running the application should be configured to the same subnet as the router to which the DVK-300HD devices are connected.

    7. DVK-300HD Utility User Interface 7.1 Keying Colour Selection and Key Mask Setting The first step is to select the mode of operation in the Mode section – the Chroma key button. The Mode section Next, the colour to be keyed out should be selected. This setting depends on the keying background used.
  • Page 15 Show alpha matte function The Show alpha matte view The intended result is to make the mask background colour as close to perfect black as possible. In order to do that the Black level slider should be moved until black is distributed as evenly as possible on the mask background.

  • Page 16: Correction Of Object Edges And Sharpness

    If the slider is moved to the extremes, the other objects will lose their properties and become non-transparent; this is why the function should be applied sparingly so that small differences are still discernible in the distribution of the black background. The successive step is to obtain a uniform distribution of white on objects which will remain fully non-transparent.
  • Page 17 In this case, in order to adjust the grayness, two further functions from the Tolerance correction section are needed. The first one is called Color and its use leads to the restoration to a uniform black structure of the background. The Color slider The other one, Luminance, improves the structure of the uniform colour of the white mask.

  • Page 18: Removal Of Keying Colour Remains (Despill)

    7.4 Removal of Keying Colour Remains (Despill) Once the correct mask is set, the functions in the Spill correction section will eliminate the reflection of the colour of the keyed background in the object. Impact of the background colour on the object – a view before a Despill correction Despill color and Despill coarse belong to the functions for the preliminary elimination of unwanted colours, and are based on the RGB space.
  • Page 19 A view after the green component has been eliminated Another function enables a more accurate adjustment of the above problem. The use of the Despill fine function eliminates the keyed background colour from the object, but this time on the basis of the chrominance components. The Despill fine slider After the application of Despill coarse, which is used for preliminary correction, more accurate adjustments can be made, and so the Despill fine settings may not have any...

  • Page 21 A view from the camera area By cutting the remaining elements by means of the sliders Left, Right, Top, Bottom, it is possible to place the object within the area of the keyed background. A view after a Garbage mask correction with the keying algorithm switched off After enabling the chroma keying function, the following effect is obtained.

  • Page 22: Post Correction

    A view after the Garbage mask correction with the keying algorithm switched on Comments: It should be kept in mind that in this case the object may only move within the area of the cut off mask – otherwise the object will disappear. Furthermore, if the Garbage mask sliders are used, it is possible to check whether the previous settings were correct and whether they had any influence on the final look of the virtual background.

    Contrast – this enables the contrast between colours to be increased. Saturation – this enables colour saturation to be boosted. Ambient Color – this enables an ambient component to be introduced into the picture. Intensity – this enables the ambient colour intensity to be set. The post correction function is usually used to match an object to a background.
