    Cv-a1-20 binning mode bi is a function where the signal charge from 2 or more adjacent pixels are added together and read out as one pixel. A resulting full frame with lower resolution can be read out with a higher rate. By adding 2 pixels together, the sensitivity is doubled. The cv-a1-20 has both ...

    Cv-a1-20 6.2. Input-output of hd/vd signals 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. If no external sync signals are applied, the camera will operate with its i...

    Cv-a1-20 6.3. Continuous operation (non triggered) trigger mode normal. Tr=0. It is for applications where the camera is continuous running without external trigger. In normal mode the shutter mode can be normal or programmable exposure. (sm=0 sm=1). The shutter will work in all 16 steps up to 1/140...

    Cv-a1-20 6.4. External trigger modes this camera has 6 external asynchronous trigger modes, which can be set by rs-232c commands. 1. Edge pre-select mode.Tr=1 pre-selected exposure. (sm=0, sm=1) 2. Pulse width control mode. Tr=2 pulse width controlled exposure. (hc=0, hc=1) 3. Frame delay read out m...

    Cv-a1-20 6.5. Edge pre-select mode the exposure starts at the first hd pulse after the trigger leading edge. It stops and is read out after the duration of the shutter time selected. It can be the first 9 step in normal or 1023 steps in programmable shutter. Sm=0 or sm=1. Shutter selections sh ≥10 w...

    Cv-a1-20 6.6. Pulse width control mode in this mode the exposure starts from the leading edge of the trigger pulse. It stops at the trailing edge of the trigger pulse, and the resulting video is read out. The accumulation can be either h synchronous or h asynchronous. Hc=0 or hc=1. In h synchronous ...

    Cv-a1-20 6.7. Frame-delay read out mode in this mode the exposure starts from the leading edge of the trigger pulse. It stops at the trailing edge of the trigger pulse. The accumulation can be either h synchronous or h asynchronous. Hc=0 or hc=1. In h synchronous mode the accumulation starts at the ...

    Cv-a1-20 6.8. Long time exposure mode the exposure time is the interval between 2 external vd pulses sent to the vd input. The exposure starts after the input of a vd, and it ends after the next vd input, which again starts a new exposure. The interval between the external vd pulses (exposure time) ...

    Cv-a1-20 6.9. Start/stop mode the exposure is controlled by the interval between the external trigger pulse and an external vd pulse. The exposure start at the first hd pulse after the trigger leading edge, and it stops after the rising edge of the vd. An een pulse will indicate the active accumulat...

    Cv-a1-20 6.10. Smearless mode this mode will reduce the unwanted smear signal from a highlighted scene when a short exposure time is used. The trigger mode is like edge pre-select, but a dummy readout is performed before the active accumulation is started. It will remove the smear above the highligh...
