Appeal No. 2000-1735
Application No. 08/780,930
by photo-electric elements are read out through vertical and horizontal transfer CCDs to
generate the image, and a quadruplication, or zoom, mode, wherein only those charges for
a portion of each scan line are used to generate the image. Further, a black level for the
quadruplication, or zoom, mode is based on charges read out during a front portion of
each such line while the black level for the normal mode is based on charges read out
during a back end of the line signal.
Independent claim 1 is reproduced as follows:
1. A digital video camera, comprising:
a CCD imager including a plurality of vertical transfer CCDs which
read-out charges stored in a plurality of photo-electric conversion elements
and successively transfer read-out charges in a vertical direction, and a
plurality of horizontal transfer CCDs which successively transfer charges
transferred from said plurality of vertical transfer CCDs, in a horizontal
direction;
a switching means for switching a first mode that a whole of each line
signal outputted from said CCD imager is utilized for displaying an image
and a second mode that only a portion of each line signal including a front
end of each line signal outputted from said CCD imager is utilized for
displaying an image;
a first period defining means for defining a first predetermined period
at a back end of said line signal in said first mode;
