VC1 Main Contrast Control Characteristics1

Measuring the amplitude output at OUT (33, 38, 41). The measured value is called VOUT (33, 38, 41).

Main contrast control characteristics VC1 is calculated by the equation below:

VOUT

VC1 = 20log 0.7 (dB)

∆VC1 Main Contrast Control Relative Characteristics1

Relative characteristics ∆VC1 is calculated by the equation below:

∆VC1 = VOUT (33) / VOUT (38) ,

VOUT (38) / VOUT (41) ,

VOUT (41) / VOUT (33)

VC2 Main Contrast Control Characteristics2

Measuring condition and procedure are the same as described in VC1.

∆VC2 Main Contrast Control Relative Characteristics2

Measuring condition and procedure are the same as described in ∆VC1.

VC3 Main Contrast Control Characteristics3

Measure the amplitude output at OUT (33, 38, 41). The measured value is called VOUT (33, 38, 41).

∆VC3 Main Contrast Control Relative Characteristics3

Measuring condition and procedure are the same as described in ∆VC1.

VSC1 Sub Contrast Control Characteristics1

Measure the amplitude output at OUT (33, 38, 41). The measured value is called VOUT (33, 38, 41).

Sub contrast control characteristics VSC1 is calculated by the equation below:

VOUT

VSC1 = 20log 0.7 (dB)

∆VSC1 Sub Contrast Control Relative Characteristics1

Relative characteristics ∆VSC1 is calculated by the equation below:

∆VSC1 = VOUT (33) / VOUT (38),

VOUT (38) / VOUT (41),

VOUT (41) / VOUT (33).

VSC2 Sub Contrast Control Characteristics2

Measuring condition and procedure are the same as described in VSC1.

∆VSC2 Sub Contrast Control Relative Characteristics2

Measuring condition and procedure are the same as described in ∆VSC1.

VSC3 Sub Contrast Control Characteristics3

Measure the amplitude output at OUT (33, 38, 41). The measured value is called VOUT (33, 38, 41).

∆VSC3 Sub Contrast Control Relative Characteristics3

Measuring condition and procedure are the same as described in ∆VSC1.
