charge flows into the deeper wells toward the electrode
at H2. At t3, the electrode voltage has not changed
since t2, so the charge flows into the wells at H2 and
one transfer of charge is completed. These operations
are repeated to execute the horizontal transfer.
7.3 SPECTRAL RESPONSE
7.4 FIELD MODE AND FRAME MODE
Standard factory setting for this mode selection is
FIELD MODE.
The difference of these two modes is as follows:
FRAME MODE
It scans each horizontal row as interlace scanning.
During FRAME MODE, integration of each pixel is one
frame period ( 32msec ...EIA, 40msec...CCIR).
Vertical pixel resolution is good and exact location is
obtained. It tends to show vertical Moire. For strobe
lighting, it must use FRAME MODE in order to achieve
full frame resolution.
FIELD MODE
It scans two horizontal rows together and changes the
pair at each interlace scanning.
This mode has advantages when the shutter is often
used as the sensitivity of the CCD is doubled for one
field of integration ( For shutter, integration can not
exceed one field ) therefore, it can obtain the same
sensitivity as the FRAME MODE for half of the period.
Because of alternating two row scanning, Moire is
almost unnoticable and even though the vertical resolu-
tion is not as good as in FRAME MODE it is sufficient
to see the full vertical resolution of the TV format.
FIELD MODE can not provide full frame resolution with
strobe lighting application.
NOTE: The factory setting for the TM-7 series cameras
is FIELD MODE. If FRAME MODE is required please
contact PULNiX for the setting.
The mode selection is solder jumper on the process
board.
