HVS color model
Each color is structured by Hue(H), Saturation(S) and Value(V). Color model corresponds to a conical subset in coordinate. The top surface of cone corresponds to V=1. Hue(H) is given by the degree of rotation angle considering V as axis. Red corresponds to 0°, green corresponds to 120°, blue corresponds to 240°. Saturation(S) is valued from 0 to 1. At the vertex of cone, V=0, H and S are not defined, which means black. At the center of cone’s top surface S=0, V=1, H is not defined, which means white. From the point to vertex of cone represents increasingly dark grey. S=0 and value of H is not defined among those points.

Gain control: Manual, automatic
Exposure control: Manual, automatic
1.Since the brightness of LED of well-encased remote controller is relatively low, it must be tested in black box to avoid affection from other light.
2.It is a must that there is a fixture to hold camera, PCBA of remote controller and the remote controller itself to make sure the relative position of each part is fixed in order to stabilize the outcome of test.
3.Now WNC and ALPHA have adopted this test method.
