6.2. Camera’s functions
6.2.1. Shutter Speed
You can set the exposure time (electronic shutter speed) of the camera in 1-line time units.
The exposure time can be calculated by the following formula.
Exposure time = 1 line time * (number of lines in 1 frame –shutter speed related register setting
value) + 13.73 [μsec]
The 1-line time does not change even if the mode changes.
1 line time = 13.28us
When all pixels are output (2448 x 2048)
1 line time = 13.28 [μsec]
Exposure time (min) = 0.1 [m sec]
Exposure time (max) = 700 [m sec]
When ROI is set
1 line time = 13.414 [μsec]
When thinning (subsampling) is set
1 line time = 13.28 [μsec]
Exposure time (min) = 0.1 [m sec]
Exposure time (max) = 700 [m sec]
* If you set ROI or thinning out, the brightness of the image will change because the exposure time
will change.
If you are using the SDK, you can use the Set / GetRealExposure function to
The exposure time can be set / acquired in 1 μs units.
* If the frame rate does not improve even though ROI or thinning transfer is performed,
The shutter speed setting value may be larger than the number of effective vertical pixels.
In that case, set the shutter speed setting value <effective vertical pixel count.

6.2.2. Analog + Digital Gain
Analog gain and digital gain are installed in the sensor of this camera.
For the set value [0~480] of the software, the floating range of the gain magnification
changes from 0.0 dB to 48.0 dB.
Formula for calculating the gain magnification:
Gain [dB] = Gain’s set value / 10.0 [dB]
When the setting value is over 240, the digital gain data becomes valid.
The relationship between gain set value and magnification [dB] is shown as below:
6.2.3. Black level adjustment
As for this camera, offset of the Black level is added to the data where the digital gain is applied.
The initial set value of the black level is 240 when outputting 12bits.
Therefore, the luminosity value in a light shaded state will be around 5 when outputting 8 bits (or 24
bits color)
*If you wish to change this value, please contact our sales department.

6.2.4. Mirror Reversal
The sensor utilized in this camera provides horizontal and vertical mirror reversal function.
In a normal position (of no avail to both horizontal reversal and vertical reversal), the lower left corner
of the direction in which the front of the camera is oriented is the origin (0, 0).
When horizontally or vertically reversed, the Bayer setting of the software will be automatically
converted.

6.2.5. Region of Interest (ROI)
It is possible to reduce unnecessary data as well as increasing frame rate by cutting out an arbitrary
area in the effective pixel scope.
The arbitrary area can be simply cut by specifying "starting point" and "effective pixels".
※The above image shows the positional relationship with the origin (0,0) in the upper left corner.
Please specify the “origin”by selecting the location of Effective Horizontal Origin and the Effective
Vertical Origin.
Please specify the “Effective Pixels”by selecting the Effective Vertical Pixels and the Effective
Horizontal Pixels.
Please use multiples of 4 when specifying values.
The range of values of the horizontal direction is 320~2448, and the range of values of the horizontal
direction is 4~2048.
For instance, if specify the effective horizontal starting point as 128, the effective vertical starting point
as 64, the effective horizontal pixel as 1280, and the effective vertical pixel as 640, then the cut area is
shown as below. In such a case, the frame rate is around 110fps (reference value).

- 13 -
6.2.6. Thinning (subsampling) settings
It is a function to reduce the total amount of transferred data and improve the frame rate by skipping
the pixels.
This sensor supports horizontal / vertical 1/2 thinning mode. (The resolution in 1/2 thinning mode is
1216 x 1024.)
As shown in the figure below, skipping is performed while leaving the Bayer pattern, so color
information is not lost.
* Cannot be used in combination with ROI settings.

9. System Requirements
9.1. Recommended System Requirements
●Host Controller
This camera is applicable to USB 3.0.
Connecting to USB 2.0 host controller may cause low-speed or failure to function properly.
●CPU
The driver of this camera is applicable to computer architecture “x86”or “amd64”.
The specification of CPU effects directly the imaging process speed, therefore it is highly
recommended to utilize a high-end CPU if possible.
●Memory
In the viewer software, there is a data buffer which can store 4 to 8 frames.
Therefore, it is necessary to keep spare space at least for 8 frames in the memory.
(For example, when using 1.3MP color camera, 1280 x 1024 x 3 x 8 [byte] = 30[MB] is
necessary.)
It is highly recommended to keep enough memory space especially when using high resolution
camera.
●OS
This camera is applicable only to the architecture of Windows NT (32bit/64bit).
Standard functions are confirmed with OS after Windows 7.
In addition, it is recommended to use Windows 10.
Caution
■Please refer the restrictions below when you use ARTCAM series.
(1) Recommended System Requirements
If the system specifications do not meet the requirements recommended above, it may be difficult to
run at the maximum frame rate.
(2) Use of other USB3.0 Hardware
The data on our camera/converter is transferred in bulk mode. For this reason, when using our
camera/converter, please avoid using other bulk transferred USB3.0 hardware such as Memory stick,
External HDD, External DVD, CDROM etc.
As a solution, we recommend installing a PCI USB host card to the PC and connect external USB
hardware to this port only.
(3) USB3.0 Cable Extension
We cannot guarantee the functionality of the USB3.0 camera if the user adopts USB3.0 extension
cables or repeaters which are not confirmed by us. With the extension cables or repeaters, the
bandwidth of transfer may differ, and thus caused malfunctions such as a low frame rate or recognition
failure on the camera.
What may cause the problem is that the regulation of the power lines becomes not enough, and so
causes impudence mismatch on data signals.
*For the recommended extension cable, please contact our sales department.
