Modern HDTV lenses can still produce optical distortions. One of these

called “lateral chromatic aberration” can be reduced in certain lens

models when used with the SK-UHD4000 camera system. The SK-

UHD4000 camera's function is called RLAC (Real-time Lens Aberration

Correction) and it dynamically corrects images using correction data

provided by the lens, through a digital interface with the camera.

Precise focus can be easily achieved with the aid of Hitachi's viewnder

Focus Assist functions. There is a Linear Focus indicator at the bottom of

the viewnder display, a Pixel-to-Pixel function that displays an enlarged

image without re-sizing and Edge color peaking which emphasizes the

in-focus area in an easily visible color

. Each focus assist function can be

selected in the VF menu according shooting conditions and can be

activated when the camera operator begins to focus.

High Chroma Detail

The High Chroma Detail adjustments allow precise control of the detail

level in highly color-saturated portions of the picture such as the petals

of a rose or a colorful fabric.

Skin Tone Detail

The Skin Tone Detail functions allow a esh-color based softening of

the image to achieve a more youthful look for on camera personalities.

Two individual memories exist as well as a function to automatically

detect the hue, saturation and luminance of the skin tone to be aected.

Furthermore, the Skin Tone Detail level can be adjusted to follow the lens'

zoom to avoid 'rubber faces' in wide angle shots while using the function.

Black Gamma

The SK-UHD4000’s Black Gamma function can control Initial Gamma

gain more nely than conventional black stretch.

Independent Initial Gamma controls are provided for the Red, Green

and Blue channels providing a ne granularity control over dark colors.

Black Stretch

The SK-UHD4000’s Black Stretch function allows for better

reproduction of dark or underexposed areas by evenly raising the

luminance response without changing the pedestal or white clip/ knee

settings. It is especially useful in high contrast shooting conditions.

Triple-Masking

The Triple-Masking function includes 12-vector, linear matrix and skin

tone masking providing users wide latitude in subject image color

control. The 12-vector color corrector provides independent control of

hue and saturation for six primary and six secondary combinations of

colors. A 6-axis linear matrix provides overall color control for excellent,

precise color rendition control. The skin tone masking function provides

“ne painting” (hue and saturation) of skin tones without aecting other

colors in the scene.

Prompter and Floor Monitor Power

The SK-UHD4000 camera system provides plenty of power to drive

two 24-inch LCD monitors. This makes for a cleaner, more reliable

install and avoids safety issues with multiple cables on your studio oor.

Ultra Gamma

A useful function implemented in the SK-UHD4000 is Ultra Gamma,

which provides seven different responses to dramatically increase

exposure latitude of

the camera in shooting

conditions where lighting

and scenery vary widely in

intensity.

Preset Masking

The Preset Masking function recalls known industry standard

colorimetry values that are precisely calibrated at the factory.

These color standards are: STANDARD (Hitachi standard) / ITU-709 /

SMPTE240M /SMPTE-WIDE / NTSC / EBU.

Knee Saturation

Washed out colors are faithfully reproduced in bright areas of the image

with the Knee Saturation control.

Chroma Saturation

Total Chroma Saturation allows control over the amount of color in the

image. A purely black & white image can be also be achieved.

Auto Chroma

Auto Chroma automatically reduces over-saturated colors in the image

caused by extremely bright and colorful objects such as emergency

vehicle lights or stage lighting LEDs.

Also has the eect of ‘legalizing’ the color gamut of a particular preset

masking setting.

Floor Monitor Digital Video

The studio oor or talent monitor can be driven with SDI (digital) video

for critical viewing by the talent.

Gray-Scale Automatic Setup

Hitachi’s Gray-scale auto-setup accurately adjusts the video

parameters of the camera by using an external known reference,

under actual lighting conditions, compensating for the lens in use.

Color matching can easily be accomplished by employing this unique

function.

RET/INCOM Handle Switches

RET and INCOM talk switches

are located on the handle for easy

operation in hand held and low

angle shooting.

Dual Filter Wheel with 10 Optical Filters

SK-UHD4000 offers two remotely

controlled lter wheels as a standard

feature. A total of 10 optical filters

are available: 4 ND filters and a

cap on one wheel and 4 color

correction filters and an effect on

another wheel. Optical lters are the

preferred method of color correction

or attenuation to preserve the

camera's signal to noise ratio and

color reproduction delity.
