Full HD Global Shutter Block Cameras


Global Shutter Block camera
Global Shutter 30x optical zoom

skoopia has recently introduced three new Full HD global shutter block cameras. 10x, 30x and 36x, allowing you to combine the advantages of global shutter cameras (synchronisation, trigger, strobe, viewing fast moving objects without image deformation) with the advantegous of block cameras (auto focus, optical magnification). All global shutter cameras can be controlled the well known VISCA commands


10x global shutter block/ 30x global shutter block G21Z10S/G21Z30S

The skoopia 10x G21Z10S and 30x G21Z30S have form factors known from their rolling shutter block equivalents (21Z10S and 21Z30S), and are equipped with a global shutter sensor (AR0234) while offering an extensive set of VISCA commands for trigger and strobe.


Ruggedized 36x global shutter block G20Z36S-R/ G20Z36S-RS

The skoopia 36x is special in that it has been designed to meet harsh environments. Its ruggedized optics have withstand the military shock and vibration tests (MIL-STD-810), combining excellent image quality (Sony IMX392 sensor) in harsh environments. The ruggedized 36x global shutter block comes in two flavors having different video output.

G20Z36S-RS: native HD-SDI, EX-SDI, TVI and CVBS video ouput


Naturally it provides control via VISCA.

Below you find the extensive trigger and strobe control support on the 10x and 30x global shutter block camera


6.1. Trigger Control

Free Run:

The camera operates without a trigger signal and performs the video output operation continuously after the shutter (exposure) is finished. The horizontal and vertical timing signals are generated within the camera. During the free-run operation, image pickup timing cannot be controlled. In the free-run operation, the adjustment is made automatically to achieve the maximum frame rate according to the shutter setting.


Trigger mode :

Exposure is started by detecting the externally input trigger signal. When ExposureDetection is

EdgeDetection, exposure is started by detecting the rising or falling edge of the trigger signal and the trigger edge detection (exposure is performed based on the set shutter value) is performed.


When ExposureDetection is WidthDetection, the trigger width detection (exposed for the period of

the trigger signal width) is performed.

  • Manual Focus and manual exposure are forced when trigger mode.


Related Command

  • CAM_TriggerMode: OFF(FreeRun)/ ON(Trigger mode)

  • TriggerSource : OFF / Internal Sync / External Trigger / SOFT (command)

  • ExposureDetection

Different trigger signals for global shutter block cameras

In CAM_TriggerMode is ON and TriggerSource is Ext Trigger, Exposure is started by detecting the

externally input trigger signal. When ExposureDetection is EdgeDetection, exposure is started by

detecting the rising or falling edge of the trigger signal and the trigger edge detection (exposure is performed based on the set shutter value) is performed. When ExposureDetection is WidthDetection, the trigger width detection (exposed for the period of the trigger signal width) is performed.


Related Command

  • TriggerExpMode: edge detection/ width detection


Trigger Edge Detection

the camera exposure starts at the falling edge of the trigger pulse or positive edge when setting is “Trigger Polarity is ActiveLow”, the camera exposure starts at the falling edge of the trigger pulse.


Exposure duration time is preset by the “Electrical Shutter” settings.

  • Trigger Width Detection

  • Trigger Source

This can be input via the 9pin FFC connector, KEL 30pin connector, or software command (SOFT).


Related Command

  • TriggerSource: OFF / Internal Sync / External Trigger / SOFT

  • Trigger range limit

Only signals in the set trigger width can be accepted as the trigger signal. This functions as a noise filter, which removes chattering or disturbance noise in the trigger signal line. This also functions as a trigger selector, whereby only a specific camera can be operated by the trigger when multiple cameras share one trigger signal line. When the trigger signal is input, exposure is started immediately to increment the trigger counter; however, when trigger width is out of the range, video is not output and the trigger counter is decremented. If the shutter time is set shorter than the upper limit, triggers will be received and video is output even if the trigger signal is wider than the trigger range limit. If the trigger source is soft trigger, trigger range is not enabled.


Related Command

  • TriggerRange : OFF/ ON

  • TriggerRangeLowerLimit : 1~2,000,000 Trigger range lower limit [μs]

  • Trigger Delay

  • The camera can delay the trigger signal.

  • Related Command

  • TriggerExDelay : 1~4,194,303 μs

  • TriggerDelay: 0 ~ 255.9 ms

  • AcquisitionMode

Only signal in the SOFT trigger source can be accepted as the acquisition trigger signal.

Continuous : Continuous acquisition in SOFT trigger mode. The Frame acquisition start trigger is

coming from the AcquisitionStart command. Images are picked up until AcquisitionStop command. The exposure time is performed based on the set shutter value.

  • SingleFrame : One Frame image pick up after AcquisitionStart command.

  • MultiFrame : Multiple Frame images pick up after AcquisitionStart command.

  • Related Command

  • AcquisitionMode : Continous/SingleFrame/MultiFrame

  • AcquisitionFrameCount : Number of frames to acquire in MultiFrame Acquisition mode.

  • AcquisitionStart, AcquisitionStop : Software trigger start or stop


6.2. Special Trigger

When operating in trigger mode and performing image pickup in different conditions (such as the shutter, gain, and image pickup area), the setting has to be changed in advance for each trigger input. However, if the special trigger operation is enabled, the setting does not have to be changed and continuous image pick up in different conditions is facilitated. Up to 16 settings can be configured. There are the bulk operations in which images are taken consecutively by inputting the trigger signal once and the sequential operation in which images are taken each time the trigger signal is detected. The next exposure is started after the end of video output. In the sequential operation, the second and subsequent trigger signals should be input 5 ms or more after the end of video output. During the special trigger operation, the device cannot be entered to the trigger mode. The source and polarity of the special trigger signal should be defined separately from the trigger mode. Each setting should be saved in the user set.


Bulk Trigger

Different camera setting configurations are stored in memory channels beforehand, with the different settings applied to acquire multiple video images at each trigger event. In the following diagram, two images are acquired in one cycle.


Sequential Trigger

Different camera setting configurations are stored in memory channels beforehand, with the different settings applied in sequence to acquire a different image with each trigger event. In the followingdiagram, two images with different exposure settings are acquired in one cycle.


Burst Trigger

This is a feature capable of continuous shooting at the trigger timing and specifying the number of exposures, exposure interval, and exposure time. Select from the mode that repeats one exposure time or the mode that switches between 2 exposure times repeatedly. Furthermore, there is another mode that repeats only while the trigger signal is on.


6.3. Strobe Control

Strobe mode :

  • ON : CMOS exposure active signal

  • Night Only : Indicate Night signal

  • Day Only : Indicate Day signal

  • Level Low : This function can set low level

  • Level High : This function can set high level

  • Ext trigger through:


Ext trigger with delay : Strobe control signal with strobe delay and strobe width.

  • FVAL(CMOS) : Frame Valid (CMOS Readout)

  • LVAL(CMOS) : Line Valid (CMOS)

  • FVAL(ISP) : Frame Valid (ISP output)

  • LVAL(ISP) : Line Valid (ISP output)

  • PWM : Pulse generation signal. PulseCycle, PulseDuty

  • USEROUTPUT1 : user defined output

  • USEROUTPUT2 : user defined output

  • USEROUTPUT3 : user defined output


Related Command

  • StrobeExDelay, StrobeExWidth : StrobeWidth can be enabled when StrobeMode is ext trigger with delay

  • PulseDuty, PulseCycle : cycle = duty(high level) + low level

  • StrobePolarity : ActiveLow(fallingEdge) / ActiveHigh(risingEdge)


The skoopia 10x and 30x are perfect replacements for previous global shutter cameras (often Sony CCD blocks) as they support the interfaces known (KEL interface for replacing the HD models) and 9 pin FFC replaceing the analog blocks while offfering extensive trigger strobe control.
