Image Enhancement

The XH G1 and XH A1 provide advanced features that improve image

viewability and maximize visual appeal. Skin Detail mode minimizes

imperfections, such as blemishes and wrinkles, without removing

detail in other areas of the image. Three intensity levels are provided,

and an alternating zebra pattern in the viewfinder simplifies

the process of selecting the desired

area for the effect. Sky Detail can be

used to enhance outdoor footage by

removing unwanted detail and noise in

the sky. Clear Scan eliminates the flicker

and black bands that usually result

when shooting a computer or other CRT

screen. Frequency is adjustable from

50.2 Hz to 200.3 Hz to accommodate a

wide variety of monitors.

Program AE Modes

Seven programmed Auto Exposure modes

simplify the selection of camera settings

for a variety of everyday and special

shooting situations.

Easy Recording—This “point-and-shoot”

mode lets the camera make all the key

decisions. The camcorder automatically

sets focus, shutter speed, aperture,

gain, white balance, and AE program

shift as required to deliver the most

pleasing video images.

Auto—Similar to Easy Recording, this

mode also provides point-and-shoot

operating simplicity. However, it gives

the operator the option of manually

changing the settings.

Shutter Priority—The user selects the

shutter speed, and the camera auto-

matically selects the proper aperture

for correct exposure.

Aperture Priority—The user selects

the lens aperture, and the camera auto-

matically selects the proper shutter

speed for correct exposure.

Manual—The user can select any

combination of aperture and shutter

speed. Indicators in the viewfinder

show the relation of selected combina-

tions to the exposure as metered by

the camera.

Spotlight—This mode automatically

adjusts exposure for optimum results when the subject is illumi-

nated by concentrated light source (such as a spotlight) while the

background is relatively dark.

Night—The camera uses slower shutter speeds to enable capture

as ambient light levels begin to fall.

Total Image Control

By giving the operator total control of more than 23 independently

adjustable variables, the XH G1 and XH A1 enable the capture of

the perfect look in HD.

Gain Settings—Select automatic gain control or one of 3 preset gains

(low, medium, or high), which can be assigned values from -3 dB

to +36 dB.

White Balance—Numerous white balance modes are provided to

ensure color accuracy in a variety of shooting situations. The auto-

matic modes use a high-precision 128-segment through-the-lens

metering system.

Auto—Provides automatic adjustment of white balance.

Outdoor—Balances for bright sunlight (5600°K), can be customized.

Indoor—Balances for incandescent lighting (3200°K), can be cus-

tomized.

Color Temperature—Balances to a specifically selected value between

2800–12000°K in 100°K increments.

Custom Presets A and B—Enables two manual

white balance settings to be programmed for

instant recall.

Black—Three settings (STRETCH, MIDDLE, PRESS)

provide a choice of dynamic range adjustment

affecting the dark areas of the image. STRETCH

expands the range, providing greater shadow

detail. PRESS narrows the range, increasing the deep black con-

tent of the image.

Knee—Four settings (AUTO, HIGH, MIDDLE, LOW) provide a choice

of dynamic range (knee point) adjustment in the highlight areas

to control overexposure when shooting high-brightness subjects.

The HIGH setting enables high-key shooting, while the LOW setting

provides maximum protection from overexposure.

Gamma—The NORMAL gamma curve provides the best results for

conventional viewing on a TV monitor. CINE 1 creates images that

resemble the quality and appearance of film as viewed on TV. The

CINE 2 setting selects an appropriate gamma curve for images that

are to be transferred to film.

Master Pedestal—Adjustments from -9 to +9 sets the video refer-

ence black. Higher values brighten the darker areas of the image,

reducing overall contrast.

Setup Level—Black level can be adjusted from -9 to +9.

Sharpness—Image sharpness can be adjusted from -9 to +9.

Horizontal Detail Frequency (HIGH, MIDDLE, LOW)—Adjusts the H

detail center frequency. Horizontal/Vertical Detail Balance (-9 to +9)

adjusts the H/V proportion of the detail correction.

Noise Reduction 1 and Noise Reduction 2 (both with OFF, HIGH,

MIDDLE, LOW settings)—Provide a variety of methods and levels

of noise reduction to accommodate numerous shooting situations

and desired image qualities.

Color Matrix—NORMAL, CINE

1, and CINE 2 adjust the color during the

shooting. The NORMAL setting is a matrix based on the assumption

that images will be reviewed on a TV monitor. If CINE 1 is selected,

the resulting quality and grayscale resemble those of a movie film.

This is a matrix for creating images on TV that appear like movies. The

CINE 2 setting is a matrix that is for images being transferred to film.

Color Gain/Phase—Adjustable from -50 to +50 and -9 to +9

respectively.

Master Red, Blue, and Green Gain settings—Independently adjustable

from -50 to +50, provide precise control over color balance.

Six Color Matrixes—RG, RB, GR, GB, BR, and BG matrixes, each

independently adjustable from -50 to +50, provide even finer color

control capability by altering two of the three primaries.

Canon Console Software

Canon Console is an advanced software package developed to

address the creative needs of XH G1 and XH A1 users. Incorporating

many of the traditional aspects of a camera control unit, Console

runs on a laptop or desktop computer and provides tools for creative

expression as well as remote access to basic camera settings and

operations. Functions, such as a vectorscope and waveform monitor,

enable critical evaluation of the

camera signal. Users can also

capture the camera’s video output

directly to a computer’s hard drive.

Console’s REC PANEL includes

five windows:

Rec Viewer—Live video, clip count-

er, audio meter and controls,

color/monochrome settings,

split-screen, and zebra levels.

Camera Control—Remote opera-

tion of most camera functions.

Vector and Waveform Monitors—

Professional tools for checking

video signal quality.

Focus Assist—Aids for achieving

precise focus, such as electronic zoom and black-and-white view.

Custom Preset—Multiple settings for comprehensive image control.

Console’s PLAY PANEL features three windows that enable review

of captured footage or recall of any existing clips or stills that may

be stored on a hard drive or memory card:

Play Viewer—Displays selected clip with a running counter. Users

can adjust playback speed and view audio monitor settings.

File Browser—Enables users to select the clip to be shown in the

Play Viewer.

Vector and Waveform Monitors—Enables critical evaluation of

recorded material.
