Color Matrix Adjustment. JVC GY-HM710, GY-HM750

Camera Features

Color Matrix Adjustment

The color matrix of the camera recorder can be adjusted to a color of the user’s preference.

When shooting is performed using multiple cameras, the colors of the different cameras can be adjusted, and a color of the user’s preference can be set on this camera recorder.

13 saturation parameters and 3 hue parameters are available for adjustment. Adjust the color on the vector scope and waveform monitor using the color chart.

* The adjusted values of AStandardB, ACinema VividB, and

ACinema SubduedB in [Color Matrix] can be stored individually. (A Page 83)

Select [Color Matrix] or [Adjust] in the [Camera

Process] menu. (A Page 86)

Adjust the saturation.

● Use the cross-shaped button ( JK ) to select a value.

● The correction range (gray area in the chart below) for each of the 12 levels from [Mg&R Mg Level] to [B&Mg Mg

Level] changes in the direction indicated by the arrow on the vector scope.

Adjust Yl&G Mask Range.

Adjusting [Yl&G Yl Level] and [Yl&G G Level] may also affect the I-axis (color close to the skin tone). When [Yl&G Yl Level] is increased, the skin tone becomes slightly more yellowish.

On the other hand, when [Yl&G G Level] is increased, the skin tone becomes slightly more greenish.

Adjust [Yl&G Mask Range] if you want to increase YI&G toward yellow and green without affecting the skin tone. As illustrated in the chart below, [Yl&G Mask Range] adjusts the gray area from the R-axis, which disables the [Yl&G Yl Level] and [Yl&G G Level] adjustments.

Increasing the [Yl&G Mask Range] value widens the masking range. By doing so, the effect on the I-axis (color close to the skin tone) due to adjustments of [Yl&G Yl Level] and [Yl&G G Level] is reduced. However, this also reduces the amount of correction by [Yl&G Yl Level] and [Yl&G G

Level].

Adjust the hue.

Adjust the hue based on the R-, G-, and B-axes.

As illustrated in the chart below, increasing the value rotates the hue in the anti-clockwise direction on the vector scope, with the respective axes as the center. Decreasing the value rotates the hue in the clockwise direction.
