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).
