This image processor digitally processes the input video signal to reduce dot interference and
cross-color problems while improving the quality of color reproduction. The unit doubles,
quadruples the horizontal scanning frequency, doubles the fields, and converts to PC formats
(of 800 x 600 and 1024 x 768). (Model IPS-4000 doubles the horizontal scanning frequency and
doubles the fields only.) This Image processor reduces line flicker, increases the vertical
resolution, and permits a video output matched to the display region of matrix type display
devices.
•
Functionally adaptive 3-dimensional Y/C separation circuit greatly reduces Y
signal and C signal crosstalk, dot interference and cross colors.
•
Functionally adaptive 3-dimensional scanning line interpolation circuitwhich
also supports PAL and SECAM, provides a reduction of line flicker and a
smooth moving picture image quality for changing still and moving pictures
by means of the original interpolation process motion detection.
•
Digital video noise reduction circuit greatly improves the signal-to-noise ratio
of the signal and outputs an image (permitting 3-stage switching) with little
noise.
•
Equipped with a still picture function for the images of document cameras.
•
Equipped with a demonstration split function for switching between the
interlace mode and the artficial interlace mode.
•
One-line type TBC(Time base corrector) function increases the margin corre-
sponding to the VCR nonstandard signal input and reduces the horizontal
jitter at the time of VCR playback.
•
The higher bandwidth of the chroma signal which is due to the color transient
correction circuit serves to raise the resolution of the color signal.
