CV-M91 1. General The CV-M91 3 CCD RGB color camera is a new updated version of CV-M90. The prism is improved, and new CCD sensors are used. The new CCD sensor has 5 dB higher sensitivity, 15 dB lower smear and 4 dB higher dynamic range. Now there are Y/C output and input for composite sync. Pulse width control shutter is now fully implemented.

CV-M91 6. Functions and Operations The different camera modes and functions can be set by switches and jumpers. Some functions like RGB setup and white clip can only be changed via RS-232C. Function names within “ “ are names used in camera control tool. 6.1. Input/Output of Signals 6.1.1. Input/output of HD/VD In the default setting the camera will accept external HD/VD signals on pin 6 and 7 of the 12 pin Hirose connector. If external HD/VD is applied, the camera will synchronize to it.
CV-M91 6.1.2. Internal sync out/WEN out On pin #7 on 9 pin sub-D connector, the factory setting is the internal composite sync signal out. By jumper settings it can be changed to WEN out. Refer to “7. Configuring the Camera.” To use this mode: Set function on PK8407: JP303 o, JP304 s for sync output. Factory default. JP303 s, JP304 o for WEN output. 6.1.3. Internal pixel clock out The internal pixel clock can be output on pin #9 on the 12 pin connector. As factory setting it is not connected. Refer to “7.
CV-M91 6.2. Trigger Modes This camera can operate in 5 primary modes. 1 non-triggered, 3 external H synchronous trigger modes and 1 long time integration mode. 1. 2. 3. 4. 5. Normal continuous Mode. Edge Pre-select Mode. Pulse Width Control Mode. Start Stop Mode Long time integration Pre-selected exposure. Pre-selected exposure. Pulse width controlled exposure. Exposure start on trigger, end after ext. VD Accumulation controlled by ext.
CV-M91 6.2.1. Continuous Operation (Non triggered) Trigger Mode Normal. It is for applications where the camera is continuous running without external trigger. The shutter will work in all 8 steps up to 1/10,000 second. Refer to “7. Configuring the Camera.” To use this mode: Set function: Trigger mode “Normal”. SW1-4 to OFF On PK8407: JP301 open, JP302 open, JP331 short. Factory setting. Accumulation to “Frame” or “Field”. SW 301-4 to ON or OFF Scanning to “Interlaced” or “Non-Interlaced”.

CV-M91 6.2.2. Edge Pre-select Mode The exposure will start at the first HD after the trigger leading edge, and it stops after the selected shutter time, and the resulting video is read out. An EEN pulse indicate the accumulation time, and a WEN pulse that the resulting video read out. Refer to “7. Configuring the Camera.” To use this mode: Set function: Input: Trigger mode to “Edge pre-select”. SW 1-4 to ON On PK8407: JP301 open, JP302 open, JP331 short. Factory setting. Accumulation to “Field”.
CV-M91 6.2.3. Pulse Width Control Mode The exposure will start at the first HD after the trigger leading edge, and it stops between the first and second HD after the trigger trailing edge. An EEN pulse indicate the accumulation time, and a WEN pulse indicates that the resulting video is read out. Refer to “7. Configuring the Camera.” To use this mode: Set function: Input: Trigger mode to “Pulse width control”. SW 1-4 to ON On PK8407: JP301 open, JP302 open, JP311 open. Accumulation to “Field”.
CV-M91 6.2.4. Start Stop Mode The exposure time is controlled by the interval between the ext. trigger and the ext. VD signal. The exposure starts at the first HD pulse after the falling edge of the ext. trigger, and stops 14.5 H after the falling edge of the VD pulse. It means that the trigger pulse must be applied after the external VD pulse, for exposures less than 14.5 H. The range can be between 1/77 to 1/10,000. The Start/Stop mode is a continuous mode where the VD signal must be given continuously.
CV-M91 6.2.5. Long time integration The exposure time is the interval between 2 ext. VD pulses sent to the VD input. (Pin No. 7 of the 12-pin connector). The exposure starts after input of the first ext. VD pulse, and ends after the next input of the next ext. VD pulse, which again starts a new exposure. The long time exposure is a continuous process where each external VD will synchronize the camera, stop the exposure, start a new exposure and read out the previous accumulated signal.
CV-M91 6.3. Other Functions. Refer to “7. Configuring the Camera.” Scanning: SW1-5 on rear selects interlaced or non-interlaced. Non-interlaced PAL = 312H in EVEN field. Non-interlaced NTSC = 262 H in ODD field. Gamma: SW1-6 on rear for gamma select. Gamma = 1 or gamma =0.45. Gain: SW1-7 on rear select manual gain or AGC. Manual gain is set by VR7 on PK8406. In AGC the gain is automatic. The AGC level is set by potentiometer VR3. Control: SW1-8 on rear selects the camera control mode.
