signal is indicated in the counterclockwise direction based on the B-Y color difference signal as a reference (color burst is specified to have an angle of 180° from the B-Y axis). In a color bar, the phase becomes larger in the order of magenta, red, yellow, green, cyan and blue. After one complete circle, it returns to the starting color, but all subtle intermediate colors are included in this 360° range. When skin color becomes pinkish or yellowish, the phenomenon is referred to as hue shifting. This occurs when the phase deviates from the normal skin color. Color temperature: A value used to express the color of light. It is used as a reference value for light sources, such as incandescent lamps, fluorescent lights and sunlight. The color temperature is expressed with the unit K (kelvin). The higher the color temperature value, the more bluish the color. A low color temperature value makes the color reddish. The AG-HVX200 allows fine adjustment of the color balance after the white balance has been adjusted. Master pedestal: The value of black in reference to the image. Knee point: The knee point is the level of compression applied to the CCD-generated highbrightness video signal to minimize washout. Gain: If the fully opened aperture cannot provide sufficient light, the image can be made brighter by electrically amplifying the video signal. Gain refers to the rate of amplification of the amp circuit designed for this purpose. For example, when the gain is 6 dB, the brightness becomes twice as high. White balance: A process of setting white color according to the light conditions at the shooting site by adjusting the color balance in order to achieve natural-looking color. ND filter: The ND (natural density) filter reduces light intensity without altering color. It is used when acquiring images in a bright place. The AG-HVX200 has two filters with light intensity reduction rates of 1/8 and 1/64. [P.38] Synchro: Phantom power supply: Synchro refers to the shutter speed used to acquire an image of a TV screen or a PC monitor. Supply of power (+48 V) to a microphone that supports phantom power supply, such as the AG-MC100G. [P.39] The lens aperture. This mechanism regulates the amount of light reaching the imaging area. Tally lamp: A red lamp that lights to indicate that the camera-recorder is recording. Squeeze: The squeeze function compresses camera images in the horizontal direction before recording. When compressed images are played back on a monitor TV compatible with the wide-screen format, they are displayed in the 16:9 aspect ratio. Letterbox: An image display format with black bands above and below the centered image. It is designed for recording wide-screen images for viewing on a 4:3 screen. Zebra function: Indicates that the brightness of the subject being shot exceeds the set value. When this happens, the zebra function shows a striped pattern to indicate the need to prevent washout. In AG-HVX200, the level set for displaying the striped pattern can be set between 50% and 105%, in 5% steps. Center marker: The marker function indicates, in percentage, the level of the brightness signal within the marker area on the screen. It indicates a level between 0 and 99%. Iris: 62
