frame per second.
●USB3.0 Interface
This camera adopts USB3.0 interface, so the data can be delivered to PC directly. No capture card isneeded.
●I n G a A s Camera Viewer Software
The camera comes with a bonded viewer software ArtMeasure (Windows 7/8/10). With this software,users can easily preview images, save images and change camera settings.
●Software Development Kit
For customer who prefers to create their own image processing software or use our camera with otherapplications, we provide SDK upon requests.

6.3.1. Shutter Speed Setting
The exposure time (electronic shutter speed) of the camera can be set in one line time resolution.
The exposure time can be calculated by the following formula:
Exposure Time = Shutter Value * One Line Time / 1000 [µsec] (Setting Range 1~65533)
The calculation formula for the one line time is different for every single mode.
Full Resolution Output（640x512）
1 Line Time = (640 / 16 + 26) * 1000 / 9 / 1000[µsec.]
Exposure Time (min) = 1 * (640 / 16 + 26) * 1000 / 9 / 1000 = 7.333[µsec.]
Exposure Time (max) = 65533 * (640 / 16 + 26) * 1000 / 9 / 1000 = 480,553.48[µsec.]≒ 480[msec.]※Long exposure (up to 10 seconds) as an option will be available in the future.

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.
●CPUThe 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] isnecessary.)
It is highly recommended to keep enough memory space especially when using high resolution
camera.
●OSThis 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 11.

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 bedifficult 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 ourcamera/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 orrepeaters, 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.
