Example of calculating Bayer output with software equivalent to mono- chrome output

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

between pixels. However, tone can be recognized in 2,000 pixel resolution

Comparing images of the same work size by BU1203MCF and BU406MCF camera with 4MCMOS, apparently image by BU1208MCF has higher resolution due to its 2 times resolution

And, image by BU1203 does not obviously show color false peculiar to single sensor camera.

Advanced Function (“MONO” output mode)

 MONO output mode from color camera

Color camera generally output signal in RGB or RAW (Bayer). This function is to get output like mono chrome camera by calculating brightness from RGB.

① Conversion from Bayer to RGB (example)

Among single plate color sensors, primary color RGB type sensor proceed through zigzag alignment (Bayer array) as chart shown in left. A screen of RGB color can be output by interpolation on each RGB element Left chart shows typical

assignment method among

various interpolation method.

Bayer array

RGB output RGB pixel interpolation

Such as enhancing image quality by neighbor pixel calculation after RGB conversion, and interpolation by calculation with

dynamic switching on detected

brightness in horizontal and vertical.

Advanced Function (“MONO” output mode)

② RGB to Y Conversion

Calculating brightness (Y) with RGB signal converted from Bayer signal, this camera outputs mono chrome signal as mono chrome camera.

Brightness signal (Y) and chrominance signal (U/V) can be calculated from RGB signal.

General formulas are ;

Y=0.30R+0.59G+0.11B

U=-0.17R-0.33G+0.50B

V=0.50R-0.42G-0.08B

Explanation of Shutter function

Doc. No. 4300-0223

2015/12/25

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 are

applied.

 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.

Sensor operation : reset➡exposure➡

reset➡exposure➡・・・

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 by

resetting on each line

 In some cases, effect of virtual global reset is achieved by high speed rolling

reset

3. Rolling shutter + global reset

 As only resetting is done in one time, exposure time after reset varies on each

line. ＝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.

Data reading

Resetting and starting exposure in all the lines at

the same time

As no difference in exposure starting time in lines like rolling

shutter, exposure starting time can be measured easily as global shutter.

Starting time of exposure is same in each line. However, exposure

time length are longer in lower line. Hence distortion and

luminance difference in image is caused under constant light.

Output image

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 cost of strobe. There is a certain advantage of easier measurement in exposure starting time comparing with rolling shutter.

Introduction of USB3.0/USB3 Vision

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 mass

storage 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 in

accordance 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.

USB3 Vision packet format

■UVC (USB Video Class) packet format

CPU analyzes header, and separate it from image data.

Over head is bigger, CPU process and communication becomes unstable.

■USB3 Vision packet format

time

CPU processing and communication is stable because of less CPU load as image data is deployed on memory at one time by DMA transfer.
