GLOSSARYOFTERMS

Iris

Works like the pupil of the human eye. In a well-lighted environment, the human pupil contracts to keep too much light from entering. In low lighting, the pupil dilates to allow more light in.

Color temperature

A measurement in Kelvin degrees which indicates the color contents of a light source; bluish light has a higher color temperature than reddish light. To reproduce white as white under different types of lighting, the chrominance signal must be adjusted to match the light source’s color temperature.

(See “White Balance”.)

AC Adapter

Used when charging the battery. Or, when connected directly to the camcorder, it can be used as a power supply.

Auto focus

Focus can be set for automatic adjustment, for beginners who find the adjustment difficult.

On-screen display

Displays in the viewfinder can be shown on a connected TV.

Strobe

In the early days of movie making, 1-second strobes were uncommon, so movies didn’t have the smooth movement they have today. This function gives movies the old-film flicker effect.

Record/Standby

Engage this mode by pressing START/STOP during Stop or Record modes. It means that the camcorder, or your VCR, is paused and ready to record.

CCD (Charge coupled device)

Solid-state imaging device used in camcorders as the camera’s image pickup; analogous to the eye’s retina except that picture information is output as electric signals.

Dew sensor

If condensation forms inside the unit due to a temperature change, the indicator appears in the viewfinder, and the camcorder becomes unusable.

Digital zoom

10x Optical zoom image is taken and digitally processed to provide 20x or 100x magnified images.

Digital Image Stabilizer

When shooting while holding the camcorder in your hand, even if you think you’re perfectly still, there is slight movement. This function compensates for that movement.

Fade

An effect used in scene transitions. Like movies or TV, the scene gradually goes black or white (fade out), or comes in from a black or white screen (fade in).

One of the television color system standards; used in the U.S., Canada, Mexico, Japan, and other countries. Other standards include PAL and SECAM.

White balance

A term that refers to the correctness of color reproduction under various lighting. If the white balance is correct, all other colors will be accurately reproduced.

Wipe

An effect used in scene transitions. A scene disappears as though it’s being wiped off the screen (wipe out), or appears as though it’s wiped on (wipe in).

GR-DVM1 specifications

The JVC GR-DVM1 is a remarkable piece of technology that represents a significant leap in the world of digital camcorders. Released in the early 2000s, this compact device quickly gained recognition for its innovative features and user-friendly design, catering to both amateur videographers and seasoned professionals.

One of the standout features of the GR-DVM1 is its ability to capture stunning video quality thanks to its advanced Progressive Scan technology. This allows for the recording of smoother video footage, perfect for dynamic scenes. The camcorder utilizes a 1/4-inch CCD sensor, delivering a resolution of up to 680,000 pixels, which translates to sharp, vibrant images that reflect true-to-life colors.

The camcorder's 10x optical zoom lens offers exceptional versatility for capturing distant subjects without sacrificing clarity. Coupled with a digital zoom capability, the GR-DVM1 allows users to get closer to their subjects, whether filming a scenic landscape or a candid moment at a family gathering. The lens is designed to minimize distortion, providing both wide-angle and telephoto capabilities.

Flexibility in shooting styles is further enhanced by the camcorder’s built-in digital effects, which include various transitions and filters that make it easy to add a professional touch to home videos. The ease of use is evident in its intuitive controls, enabling users to navigate settings effortlessly. An LCD screen provides a clear view while composing shots, and it's adjustable for optimum viewing angles.

Another notable characteristic of the JVC GR-DVM1 is its compatibility with various recording media. It supports MiniDV tapes, which were popular at the time for their reliability and quality. This format also makes it possible to obtain recordings that can be transferred to a computer for editing or archiving.

In terms of connectivity, the GR-DVM1 is equipped with FireWire (IEEE 1394) ports, enabling straightforward digital transfers to compatible devices. This allows for seamless integration into a digital editing workflow, where hours of recorded footage can be quickly imported for post-production.

The JVC GR-DVM1 not only excels in video capabilities but also includes a built-in microphone and the option for external mic support, ensuring high-quality audio to complement the impressive visuals. With its combination of advanced technology, user-friendly features, and portability, the JVC GR-DVM1 remains a noteworthy camcorder that played a vital role in the transition to digital video recording. Its legacy continues to influence camcorder design and functionality in subsequent generations.
