The replacement model, the HDR-HC7 came with a higher pixel count CMOS sensor and with a microphone input. Like the HDR-HC5, the HDR-HC7 could also record xvYCC. In 2008 the HDR-HC7 was replaced with the HDR-HC9. In 2006, Sony added two new models to its upscale HDV lineup: the "advanced amateur" HDR-FX7 and its professional cousin, the HVR-V1 ...
Tape is enclosed into videocassette of four different sizes: small, medium, large and extra-large. All DV cassettes use 1 ⁄ 4 inch (6.4 mm) wide tape. DV on magnetic tape uses helical scan, which wraps the tape around a tilted, rotating head drum with video heads mounted to it. As the drum rotates, the heads read the tape diagonally.
Canon introduced this system in 1987 along with the EF lens mount standard. The last non-EOS based SLR camera produced by Canon, the Canon T90 of 1986, is widely regarded as the template for the EOS line of camera bodies, although the T90 employed the older FD lens-mount standard. For a detailed list of EOS Film and digital SLR cameras, see ...
The measure of how closely lines can be resolved in an image is called spatial resolution, and it depends on properties of the system creating the image, not just the pixel resolution in pixels per inch (ppi). For practical purposes the clarity of the image is decided by its spatial resolution, not the number of pixels in an image.
The 8mm tape width was chosen as smaller successor to the 12mm Betamax format, using similar technology (including U-shaped tape loading) [16] but in a smaller configuration in response to the small configuration VHS-C compact camcorders introduced by the competition. It was followed by Hi8, a version with improved resolution.
A quire of paper is a measure of paper quantity. The usual meaning is 25 sheets of the same size and quality: 1 ⁄ 20 of a ream of 500 sheets. Quires of 25 sheets are often used for machine-made paper, while quires of 24 sheets are often used for handmade or specialised paper of 480-sheet reams.
In typography, the point is the smallest unit of measure. It is used for measuring font size, leading, and other items on a printed page. The size of the point has varied throughout printing's history. Since the 18th century, the size of a point has been between 0.18 and 0.4 millimeters.
Remanence of audio tapes, referred to quarter-inch tape width, varies from around 1100 G for basic ferric tapes to 3500 G for Type IV tapes; [5] advertised remanence of the 1986 JVC Type IV cassette reached 4800 G. [6] Coercivity is a measure of the external magnetic flux required to magnetize the tape, and an indicator of the necessary bias level.
