1. General
This manual will cover the following 4 cameras: CV-M4+/CV-M4+CL and CV-M7+/CV-M7+CL.
The revision B cameras are updated with a new function, Restart Continuous Trigger mode
(RCT). The trigger can be H a-synchronous or H synchronous. Binning is now only vertical.
The cameras are based on progressive scan 2/3” CCD megapixel interline transfer sensors.

The color cameras use a RGB primary color filter CCD sensor (Bayer color filter). The video
output is a single data stream with the RGB signals in sequence. The RGB color decoding should
be done in the host PC.
The cameras are designed for automated imaging applications, featuring high resolution and high
speed within a uniform and compact housing.
The high-speed shutter function, asynchronous random trigger mode and partial scan mode
allows the camera to capture high quality images of fast moving objects with a high frame rate.
It is suitable for industrial applications such as on-line inspection and measurement.
Thanks to the EIA-644 (LVDS) digital interface, crisp and clear images are achieved.

Analogue video in partial scan is only valid for the scanned area.
Important note on using this signal for iris control.
The signal for iris video output is taken from the video signal after the gain control. If it is used
for auto iris control, the digital output video level can only be adjusted with the lens level
adjust. The camera gain adjust will only change the working point.

6. Functions and Operations
6.1. Basic functions
The CCD scanning format can be selected between full or partial scanning. With partial scanning
only the vertical central part of the CCD sensor is read out with a higher frame rate. The partial
scan is done by a fast dump read out of the lines in the vertical ccd register down to the top of
the partial image. The partial part of the image is read out with normal speed. The lines below
the partial image is read out and dumped with a high speed. With partial scan the shutter speed
is limited to be shorter than the frame read out time. (SC=1 1/50. SC=2 1/100. SC=3 1/200). In
PWC mode TR=2, there is no limitation.
A minor signal distortion can be expected below highlighted areas, (saturated areas). It is caused
by limitation in the vertical ccd register transfer efficiency at high speed.
Lines shown in partial scans are: 1/2 PS 512 lines. 1/4 PS 256 lines. 1/8 PS 128 lines.

Binning mode 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 spatial resolution can be
read out with a higher rate, and higher sensitivity. The CV-M4
pixel charge from 2 adjacent lines are added together in the horizontal ccd register. It is done
by double pulses to the vertical ccd register. Lowest shutter speed is 1/50. In binning mode H is
43.3 µ sec. Binning will only work for the monochrome cameras CV-M4

trigger mode, the trigger leading edge will immediately reset the internal H timing and start the

In H synchronous trigger mode and H a-synchronous trigger mode a new trigger must not be

Multiple exposure is a function which allows several exposures with a short interval. The
exposures are all placed in the same frame. This function is useful for studies of high speed
events.
The trigger leading edge will start the first exposure (edge pre select). When it is finished, the
resulting charge is read out in the stopped vertical ccd register. With additional trigger pulses on
the multi exposure input, new exposures can be done. The charge from each is added on top of
the first charge in the stopped vertical ccd register. Up to 6 exposures can be done with multi
exposure. The trigger trailing edge will start the vertical ccd registers, and the video signal will
be read out. Fig. 13 shows the timing details.
