The camera supports multiple image formats，the ROI parameter values in the user setting will increase image
frame rate.
Color camera default output format is YUV 422 8，mono camera default output format is Mono8.
“ Y” means Support，“—”means nonsupport.
The color camera converts the original data to RGB8 via pixel interpolation algorithm.
Bayer GR，Bayer GB，Bayer BG，Bayer RG as shown as below.
Bayer GR Bayer GB Bayer BG Bayer RG
The camera with 12Bit ADC（Some model only support 10Bit ADC），but considering the user's processing
capacity of data volume, the 8bit data output is provided. In order to retain the gray level output of the
image data, the 8bits are extracted from the high-order as the output.
The corresponding numbers of Bytes to different formats are shown as below.
In the client software to find “Image Format Control” and expand it. To click “Pixel Format” you can view the
pixel format supported by the current camera to select right output mode according to your actual demands.

Image acquisition
Line Frequency
Line frequency is the number of lines that a line scan camera can acquired in a second. The line frequency of
real-time acquisition by the camera depends on the bandwidth, pixel format, line readout time and exposure
time.
Line readout time: The less time it takes to readout each line, the higher the line frequency
Exposure time: The lower the exposure time, the higher the line frequency
Bandwidth: The larger the bandwidth, the higher the line frequency
Pixel format: Different pixel formats take up different bytes, the fewer bytes the pixel format
takes up, the more line frequency the camera has.
The camera frame rate is proportional to the line frequency and inversely proportional to the height of the
image, namely, Fps=Lps/Image Height.
Via “Acquisition Line Rate(Hz)” in” Acquisition Control”, can set camera line frequency. shown as below.
www.contrastech.com
Image Acquisition Mode
The line scan camera trigger mode can be divided into SingleFrame and Continuous.
The specific working principle and corresponding parameters are as follows:
Parameters：Acquisition Control > Acquisition Mode
SingleFrame Acquisition
Mode Select：SingleFrame
Working principle: After the camera starts Acquisition images, it only Acquisition one image
and then stop
Continuous Acquisition
Mode Select：Continuous
Working principle: After the camera starts to acquisition images, images can be continuously
acquisition. The number of acquisition frames per second is determined by the real-time frame
rate, and needs to be stopped manually
www.contrastech.com
Trigger Mode
The line scan camera trigger mode can be divided into Free Trigger, Line Trigger, Frame Trigger and
Line+Frame Trigger.
Trigger can be switched by On/Off button under Trigger Mode
Under “Acquisition Control” to set specific parameters in “Trigger Selector” and “Trigger Mode”.
Acquisition Mode：
Free Trigger Mode
Trigger Selector = Line Start ；Trigger Mode = Off
and
Trigger Selector = Frame Burst Start ；Trigger Mode = Off
Working principle: the trigger signals of this mode are generated by the camera itself. The
users can adjust the line frequency parameters according to actual needs.
Line Trigger Mode
Trigger Selector = Line Start ；Trigger Mode = On
and
Trigger Selector = Frame Burst Start ；Trigger Mode = Off
Working principle: The line frequency is determined by the frequency of the external trigger
control signal. Under this mode, only one line is exposed when a trigger signal is input.
In “Trigger Source”, you can select the trigger source of line trigger. The range of trigger signal are Line0,
Line2, Line3, Encoder Module Out and Frequency Converter. Shown as below.
