Sony 3CCD-VX3 (often referred to as simply VX-3) was a Hi-8 camcorder noteworthy for being the first to feature dichroic (prismatic) imaging. It was released to the North American market in 1992 at a street cost of about US$3500. The PAL version as well as the Japanese version had the model name CCD-VX1.
The image is created using three 1/3" CCD chips by prismatically splitting the optics into red, green, and blue, and processing each of these channels individually; this preserves quality especially with red hues. The camera imaged in 410,000 pixels with horizontal resolution of better than 530 lines.
During the mid-1990s, Sony dropped Hi-8 in favor of the emerging DV format, and as a result the VX-3 was discontinued in September 1995. However the VX-3 went on to serve as the framework for a line of professional DV cameras, including the DCR-VX1000, DCR-VX9000, and DSR-200.
A charge-coupled device (CCD) is an integrated circuit containing an array of linked, or coupled, capacitors. Under the control of an external circuit, each capacitor can transfer its electric charge to a neighboring capacitor. CCD sensors are a major technology used in digital imaging.
Digital video is an electronic representation of moving visual images (video) in the form of encoded digital data. This is in contrast to analog video, which represents moving visual images in the form of analog signals. Digital video comprises a series of digital images displayed in rapid succession.
A digital camera is a camera that captures photographs in digital memory. Most cameras produced today are digital, largely replacing those that capture images on photographic film. While there are still dedicated digital cameras, many more cameras are now incorporated into mobile devices like smartphones, which can, among many other purposes, use their cameras to initiate live video-telephony and directly edit and upload images to others. High-end, high-definition dedicated cameras are still commonly used by professionals and those who desire to take higher-quality photographs.
DV is a format for storing digital videos. It was launched in 1995 with joint efforts of leading producers of video camera recorders. It is the foundation of the MiniDV format.
Digital8 is a consumer digital recording videocassette for camcorders based on the 8 mm video format developed by Sony, and introduced in 1999.
A camcorder is an electronic device originally combining a video camera and a videocassette recorder.
The 8mm video format refers informally to three related videocassette formats for the NTSC and PAL/SECAM television systems. These are the original Video8 format and its improved successor Hi8, as well as a more recent digital recording format known as Digital8.
MicroMV is a discontinued proprietary videotape format introduced in October 2001 by Sony. It is the smallest videotape format — 70% smaller than MiniDV or about the size of two US quarter coins; it is also smaller than a Digital8 or DV cassette and slightly smaller than an audio microcassette. It was the first helical scan tape system using MR read head introduced to the market. Each cassette can hold up to 60 minutes of video.
HDV is a format for recording of high-definition video on DV cassette tape. The format was originally developed by JVC and supported by Sony, Canon, and Sharp. The four companies formed the HDV Consortium in September 2003.
Handycam is a Sony brand used to market its camcorder range. It was launched in 1985 as the name of the first Video8 camcorder, replacing Sony's previous line of Betamax-based models, and the name was intended to emphasize the "handy" palm size nature of the camera, made possible by the new miniaturized tape format. This was in marked contrast to the larger, shoulder mounted cameras available before the creation of Video8, and competing smaller formats such as VHS-C.
Digital cinematography is the process of capturing (recording) a motion picture using digital image sensors rather than through film stock. As digital technology has improved in recent years, this practice has become dominant. Since the mid-2010s, most movies across the world are captured as well as distributed digitally.
Mavica is a discontinued brand of Sony cameras which use removable disks as the main recording medium. On August 25th 1981, Sony unveiled a prototype of the Sony Mavica as the world's first electronic still camera.
An image sensor or imager is a sensor that detects and conveys information used to make an image. It does so by converting the variable attenuation of light waves into signals, small bursts of current that convey the information. The waves can be light or other electromagnetic radiation. Image sensors are used in electronic imaging devices of both analog and digital types, which include digital cameras, camera modules, camera phones, optical mouse devices, medical imaging equipment, night vision equipment such as thermal imaging devices, radar, sonar, and others. As technology changes, electronic and digital imaging tends to replace chemical and analog imaging.
High Resolution Imaging Science Experiment is a camera on board the Mars Reconnaissance Orbiter which has been orbiting and studying Mars since 2006. The 65 kg (143 lb), US$40 million instrument was built under the direction of the University of Arizona's Lunar and Planetary Laboratory by Ball Aerospace & Technologies Corp. It consists of a 0.5m (19.7 in) aperture reflecting telescope, the largest so far of any deep space mission, which allows it to take pictures of Mars with resolutions of 0.3m/pixel, resolving objects below a meter across.
Digital Imaging Integrated Circuit is Canon Inc.'s name for a family of signal processing and control units for digital cameras and camcorders. DIGIC units are used as image processors by Canon in its own digital imaging products. Several generations of DIGICs exist, and are distinguished by a version number suffix.
Sony produces professional, consumer, and prosumer camcorders.
The Sony DCR-VX1000 was a DV tape camcorder released by Sony in 1995, replaced by the DCR-VX2000 in 2000 and the DCR-VX2100 in mid 2003.
The Sony DCR-TRV900 was a DV tape camcorder released by Sony in 1998, with an MSRP of USD $2699. It was intended as a high-end consumer camera, more portable and less expensive than the top-of-the-line DCR-VX1000. It became one of several Sony and Canon models popular in late-'90s desktop video production, delivering quality comparable to then-dominant analog Betacam hardware at a fraction of the cost. In 2002, Sony replaced the TRV900 with the somewhat less well-received DCR-TRV950.
A digital movie camera for digital cinematography is a video cameras that captures footage digitally rather than the historically used movie camera, which shoots on film stock. Different digital movie cameras output a variety of different acquisition formats. Cameras designed for domestic use have also been used for some low-budget independent productions.
