by different descriptors depending on the color
model being used.
handshaking the process of acknowledging transmission and
reception of data through hardware or software.
interleaved refers to a color pixel storage structure where the
RGB elements of the pixel are all present in
consecutive order at one memory location for that
pixel. Non-interleaved or planar means that the red,
green and blue pixels are stored in different planes
or files. See band sequential, byte sequential, line
sequential, full chunky, chunky planar, and full
planar.
intensity see color models.
irradiation photons entering a light sensitive film emulsion tend
to ‘bounce around’ resulting in diffusion of sharp
lines and loss of definition. This can be minimized
with thinner emulsions and a light absorbing base
under the sensitized layers.
high-key describes an image where most if not all of the
subject matter has a density range from midtones to
highlights. A predominantly light picture.
HP-IB see GPIB.
line-sequential where color is stored in RGB, YMCK, etc. lines of
pixels instead of bytes or planes. Sometimes called
row sequential for a horizontal raster.
luminance see color models.
