(Note) The above described unnatural image
represents the following states:
● Black and white look inverted at the saturating area.
● The outline of the saturating area is blurred.
● The saturating area slightly shifts upward or downward.
● The brightness of the saturating area does not reach 1023.
(5-5) AGC gain setting
AGC function turns on by setting AGCE(AGC Enable) bit in flag register(FR) to 1.
The operating range of AGC is about 20dB.
(Note) AGC setting and MGC setting are incompatible with each other.
(5-6) Output data bit format setting
Three formats below are selectable as the data format outputting with
Camera Link interface,.
8 bit Gray scale (Default)
10 bit Gray scale
12 bit Gray scale
This camera is equipped with A/D converter with 14 bit output.
8 bit to 12 bit data of the upper bits of A/D converter is output in accordance
with output format setting as the right table.
The setting is changed by rewriting (CR)(Configuration register) with serial
communication command.
(5-7) Program page setting
The FC series cameras are internally equipped with nonvolatile memories
and various operation mode settings and level settings can be stored in them.
The setting items are stored in the virtual pages (hereinafter referred to as
"program pages" inside the camera.
This camera has 6 program pages of "A", "B", "C", "D", "E" and "F" (right
figure).
The camera starts operating according to the various settings stored in the
relevant page when the mode switch is at any one of the positions from "A" to
"F" at the time of power-on.
(!) As this camera is not equipped with the substantial shutter setting switch
on the rear panel, "Mode switch" described here means setting values of
hypothetical mode switch set on the memory inside the camera.
The position of this (hypothetical) mode switch can be set, read and
saved with serial communication command.
(Note) The memory has the configuration area aside from the saving area
of the program pages that is independent from the program pages.
The common setting items (Configuration items) are saved on this area.
(5-8) Setting of Shutter switch and Mode switch
This camera is not equipped with the substantial shutter switch and mode switch. The hypothetical switches set on the memory
inside the camera are used as a substitute for these switches.
The set values of these switches are stored in nonvolatile ROM and these values are read out onto RAM at the time of power-on.
(5-8-1) Confirmation of set position of Shutter switch and Mode switch
It can be confirmed by any of the following methods.
Confirmation on the OSD menu screen
●
Current setting status of Mode switch (MS) and Shutter switch (SW) can be
confirmed by displaying the OSD menu on the captured image.
MS
Set value of Mode switch
・・・・
SS
Set value of Shutter switch
・・・・
→ Mode switch is set to A and Shutter switch is set to 2 on the right example.
