ORDERING INFORMATION
The KS7314 offers enlarged images through the zoom
effect attained by horizontal and vertical interpolation of
luminance and chrominance signal input supplied from
the CCD digital signal processor (KS7306). The signal
input is implemented by employing a 2nd generation
electronic zoom IC, which electronically enlarges the
image picked up by the CCD of a camcorder. In
addition, it corrects the wobble of hand-held cameras,
and also provides the functions of a gyro-sensor and a
mosaic mirror.
