Resolution is 2,000 lines with vertical
4,000 pixels mono chrome sensor. In
case of Bayer color, resolution must
be reduced because of calculation

Basic of electronic shutter (shutter, reset)
 Shutter mode Assigning exposure time to sensor
 Global shutter; Shutter mode which takes image by exposure for all pixels (1 frame) in one time Applied to CCD sensor and some of CMOS sensor
 Stable imaging for Motion picture and still picture Rolling shutter; Shutter mode which has different exposure timing on each line. Most of CMOS sensors areapplied.
 Digital camera, mobile phone, smart phone, web camera, low cost monitor camera, mobile
camera etc.
 Disadvantage of distortive image in motion picture Reset mode Action of clearing the information(charge, electron) in sensor before
taking fresh image
 Global reset; A mode of reset which reset all pixels in one time Rolling reset; This resets on each line.

Basic of electronic shutter (combination of shutter and reset)
1. Global shutter + global reset Complete global shutter action
 As scanning time is longer in lower part of image, black floating phenomenon
might be caused by dark current effect. ＝This can be corrected as it is slight

2. Global shutter + rolling reset Global shutter mode can reduce an effect of time difference during reading byresetting on each line In some cases, effect of virtual global reset is achieved by high speed rollingreset

3. Rolling shutter + global reset As only resetting is done in one time, exposure time after reset varies on eachline.
＝The lower part of image is the brighter as exposure time is longer.

4. Rolling shutter + rolling reset Complete Rolling shutter action
 Stable exposure process as both reset and shutter are rolling mode
 Easier to make low noise type sensor as structure of less pixel transistor number.
 As disadvantage, motion image shot under continuous light will be distortive.

Exposure time length is different in each line

As no difference in exposure starting time in lines like rolling
shutter, exposure starting time can be measured easily as
global shutter.
However, as exposure ending time is different in each line,
image of moving subject under constant light is distortive due
to luminance difference.
As a result, low cost advantage will be offset by additional costof strobe. There is a certain advantage of easier measurement
in exposure starting time comparing with rolling shutter.

Under constant light, both of global shutter and rolling shutter can beused for shooting.
In case of global reset, the lower part becomes brighter due to duration

About USB3.0
 Back ground of USB3.0
 USB was started to be used for PC peripherals such as mouse, keyboard, printer etc.
in its early stage. And USB2.0 became majority which can be connected to massstorage like HDD.
 Gradually, USB is also used for sequential data transfer such as audio and video.
 As internet is getting more popular, USB3.0 became an interface which can handle
more data. Official support to USB3.0 by Windows 8 also helps its popularity.

 Output data from camera is getting larger with higher speed than before inaccordance with transition of CCD to CMOS sensor in it.
 USB3.0 is adopted as an interface which can handle these data. USB3.0 is expected
as an interface for worldwide use by standardization of protocol as “USB3 Vision”.
 Industrial cameras with USB3.0 get ready to spread in the market with USB’s
advantage of board less use and various availability of PC peripherals.

 Transition of USB standard USB has been quite popular as
multipurpose PC interface for about
20 years since USB1.0 in 1996.

 USB3.1 standard will start following
the tremendous performance
improvement of USB3.0.

CPU analyzes header, and separate it from image data.
Over head is bigger, CPU process and communication becomes unstable.

timeheaderImage data■USB3 Vision packet format
CPU processing and communication is stable because of less CPU load as
image data is deployed on memory at one time by DMA transfer.
