Measuring Horizontal Resolution

Horizontal resolution in 16:9 mode
When the horizontal image frame of this camera is
aligned with the width of the 4:3 resolution chart, the
resolution is about 935 TV lines (see Figure A).
However, to measure the resolution of a video camera
precisely, the vertical image frame must be aligned
with the height of the chart. When this is done, the
resolution is approximately 800 TV lines (see Figure
B).
Horizontal resolution in 4:3 mode
In 4:3 mode, frame memory is used to extract the 4:3
area from the 16:9 video signals produced by the WS
CCD, and the 4:3 signals are electronically enlarged.
As a result, the horizontal resolution is approximately
850 TV lines (see Figure C).
