CV-M77
1. General
The CV-M77 camera is a compact RGB color progressive scan camera designed for automated
imaging applications. The 1/3" CCD sensor with square pixels and primary mosaic filter offers a
superb image quality and the built-in DSP assures high color reproduction.
The camera incorporates several triggered modes and various shutter functions to capture
moving objects and to control the light. All camera mode settings can be controlled via an RS232C interface or by the switch at the rear of the camera.
The CV-M77 camera is ideal for demanding color applications such as color inspection, gauging
and color printing.
Revision B is updated with the high framerate read out mode.

5.4. Input output Circuits
In the following schematic diagrams the input and output circuits for video and timing signals
are shown. For alternative connections refer to “7. Configuring the Camera”. Jumper settings
are shown as for factory default.
RGB video output
The video output signal is a RGB video signal.
The signal level is 0.7Vpp from 75Ω. The video
output is DC coupled.
Composite sync. is selectable on the green
video signal via software or the internal switch
302-3. The sync. signal level is 0.3Vpp.

Iris video output
A video signal for lens iris control is found on
pin 4. 12-pin connector. The signal is with
composite sync. It is ac coupled from a 75Ω
source. It can only be used for iris control in
normal continuous mode.
Fig. 6. Video outputs
Trigger input
The trigger input is AC coupled. To allow a
long wide pulse width, the input circuit is a
flip-flop, which is toggled by the negative and
positive differentiated spikes cause buy the
falling and rising edge. The input signal level
is 4V ± 2V. The trigger input impedance is 1.2
kΩ or 75Ω selectable via the internal switch
S301-3.
Fig. 7. Trigger input
HD and VD input
The HD and VD input circuit can be 75Ω
terminated via the internal switch S301-1 and
S301-2.
The input signal level is 4V ± 2V.

6. Functions and Operations
6.1. Basic operation modes
Apart from the standard continuous operation mode, the CV-M77 features four external
triggering modes and a long time exposure mode. In all modes the camera can be synchronized
to an external sync. The shutter time can be selected from 12 fixed steps, or from 788 steps
with 1H resolution. In triggered mode it can also be controlled by the trigger pulse width.
The frame delayed readout can operate in either edge pre-selected trigger, or pulse width
controlled shutter mode.
Switches can set most modes and functions locally. All modes and functions can be remote
controlled by RS-232C control.
Alternative connections for input and output signals can be done by internal jumpers.
For details: refer to “7. Configuring the Camera”.
6.1.1. High frame rate.
From revision C, the CV-M77 camera has a new readout mode. It is the high frame rate mode.
Here only every third line is read out. The 2 lines between are dumped. In this way the Bayer
RGB mosaic pattern is unchanged. The DSP interpolation algorithm for RGB color output can still
be used.
The figures below shows the CCD sensor in normal mode and high frame rate mode. In high
frame rate, the vertical ccd register is clocked with 3 times higher rate. But only the signals
from every third line is transferred to the horizontal ccd register for read out. Signals from the
lines between are dumped.
The horizontal resolution is unchanged, but the vertical resolution is reduced to 1/3.
The advantages are:
Frame rate 3 times higher
The image is sampled from the whole sensor area
Horizontal resolution unchanged

6.2. Input/Output of HD/VD Signal
6.2.1. Input of External HD/VD signals
This setting is factory pre-set. The video output is synchronized with external HD/VD signals if
applied. If no ext. HD signal is input, the camera will switch to the internal X-tal controlled HD
sync. If no ext. VD is connected, the camera will continue with its internal VD.
For details: refer to “7. Configuring the Camera”.
To use this mode:
Set function: SW 303.1 and 303.2 to ON for external HD/VD input. Factory default.
SW 301.1 and 301.2 to OFF for TTL level for HD/VD. Factory defaults
SW 301.1 and 301.2 to ON for 75 Ω termination of HD/VD..
Input: Ext. HD in on pin 6 on 12-pin connector. 4.0 Vp-p ±2.0V.
Ext. VD in on pin 7 on 12-pin connector. 4.0 Vp-p ±2.0V.
Important notes on using this mode
External sync system should follow the camera scanning system.
The ext. HD/VD phase relations should follow as shown in fig. 10.
Fig. 10. External VD and HD phase relation
6.2.2. Output of Internal HD/VD signals
Internal HD/VD signals can be output for synchronizing external equipment.
For details: refer to “7. Configuring the Camera”.
To use this mode:
Set function: SW 303.1 and 303.2 to OFF for internal HD/VD output.
Output: Int. HD out on pin 6 on 12-pin connector. 4.0 Vp-p from 75Ω source.
Int. VD out on pin 7 on 12-pin connector. 4.0 Vp-p from 75Ω source.

continuous operation.
Mode setting and all other settings can be done via RS 232C control if rear switch SW1-10 is ON.
Mode setting and some other settings can be done by switch if rear switch SW1-10 is OFF.
For details: refer to “7. Configuring the Camera”.
To use this mode: RS SW1-
