Only some models of cameras with rolling shutter support the Global Reset function.Global reset means that all of the sensor's
pixels start exposing at the same time, but stop exposing at different time.
When you need to use the Global Reset function, You can go to Acquisition Control > Sensor Shutter Mode, and select
Sensor Shutter Mode to Global Reset.
Rolling
Rolling means that the device exposes the pixel rows one after the other, and it supports sensor’s pixels exposure and pixel data

Sensor Shutter Mode
The sensor shutter mode allows you to set the operating mode of the device’s electronic shutter. The shutter mode refers to the
way in which the image data is captured and processed.
In general, there are 3 sensor shutter modes, including Global Reset, Rolling and Trigger Rolling.
● Only some models of devices with rolling shutter and corresponding firmware support the sensor shutter mode.
The actual product you purchased should prevail.
● Stopping the real-time acquisition is required before setting the sensor shutter mode.
● For some device models, only when Trigger Mode is On, you can set Sensor Shutter Mode.
i
● Whether the camera supports Global Reset/Trigger Rolling function depends on the specific model.
● After the Global Reset function is turned on, due to the different exposure time of each line of the image, the
brightness of each line of the image may vary from top to bottom.
Therefore, if this function is turned on, it is recommended to use it with a visual light source in a dark environment.
Turn on the light source during the exposure time shown in the figure above, and turn off the light source at other
times, so that each line of the image gets the same illumination during the same exposure time, so as to control the
brightness of each line of the image.
i
Trigger Rolling
The Trigger Rolling function is mainly used in rolling shutter cameras. This function can increase the maximum frame rate in
trigger mode, thereby increasing the drawing time. But this function does not support that sensor’s pixels exposure and pixel
data readout proceed at the same time(overlap exposure).
When you need to use the Trigger Rolling function, You can go to Acquisition Control > Sensor Shutter Mode, and select Sensor
Shutter Mode to Trigger Rolling .

Camera Features
Non-Overlap Exposure and Overlap Exposure
The process that camera captures one frame of image includes two stages, exposure and readout. According to the overlap relation
between the exposure time and the readout time, cameras with different sensors can be divided into overlap exposure and non-
overlap exposure. Compared with non-overlap exposure, overlap exposure can reduce the influence of exposure time on grabbing
time.
The products mentioned in this manual use overlap exposure to process image data.
After completing the current frame’s exposure and readout, the next frame starts to expose and read out. This process is called
non-overlap exposure. The non-overlap exposure’s frame period is larger than the sum of the exposure time and the readout
time, as shown below.

CHAPTER 5 IMAGE ACQUISITION
Frame Rate
Frame rate refers to the image number that is acquired by the camera per second. The higher frame rate, and shorter time used for image
acquisition will be.
The following 5 factors determines the camera’s frame rate in real-time.
■ Frame readout time: The frame readout time is related with camera’s sensor performance and image height. The lower the image
height and less the frame readout time, and the higher the frame rate will be.
■ Exposure time: If the reciprocal of max frame rate that the camera supports is t, and when the configured exposure time is larger than
t, the less the exposure time, the higher the frame rate will be. When the configured exposure time is less than or equal to t, exposure time
will not influence the frame rate.
■ Bandwidth: The larger the bandwidth, the higher the frame rate will be.
■ Pixel format: The more bytes pixel format occupy, the lower the frame rate will be.
■ Image compression mode: This function is used to compress data before transmitting to the PC, and increase the frame rate to some
extent.
For different models of camera, the Image compression mode may be different, please refer to the actual one you got.
i
The camera can also manually control the real-time frame rate.
The specific steps are as follows:
1.Click Acquisition Control > Acquisition Frame Rate, enter Acquisition Frame Rate according to actual demands, and enable Acquisition
Frame Rate Control Enable.
_If the current real-time frame rate is smaller than configured frame rate, the camera acquires images according to the real-time frame rate.
_If the current real-time frame rate is larger than configured frame rate, the camera acquires images by the value you set.
2.When you enable the image compression mode (refer to section Set Image Compression Mode for details), you can view the Reference
Frame Rate that is a reference rate calculated according to bandwidth and the compression ratio.
In the most undesirable situation, the actual frame rate should be less than the resulting frame rate value.
3.You can refer to Resulting Frame Rate to view the camera’s resulting frame rate.
Full Frame Transmission
The full frame transmission function is used to continue frame transmission action and have a full frame when frame acquisition stops
during the process, and the frame will be discarded if this parameter is not enabled.
Go to Acquisition Control → Full Frame Transmission, and enable it according to actual demands.
The full frame transmission function may differ by device models.
