1. General

The AT-030MCL is a digital 3CCD progressive scan RGB color camera. It employs three 1/3­inch 659 (h) x 494 (v), 320K pixel CCDs and it runs at the high speed of 120 frames per second
in full resolution mode. The AT-030MCL has a Camera Link® interface and its output can be
either 8-bit through a Camera Link Base configuration, or 10-bit or 12-bit through a Camera
Link Medium configuration. JAI developed an upgraded 1/3-inch compact F2.0 prism optical
system and, in combination with a linear color matrix circuit, the AT-030MCL provides a
higher fidelity of color reproduction than in earlier 1/3-inch models. The AT-030MCL also
incorporates a shading circuit, gamma correction circuit and knee correction circuit to
provide high picture quality. Functions like partial scanning and vertical binning allow higher
frame rates.

6. Input and output circuits

This chapter introduces the basic diagram and bit allocation of digital output.

6.1. Iris video output

This signal can be used for lens iris control In Continuous
and RCT modes. The signal is NUM luminance signal and
passes through the gain circuit. However, due to reversed
compensation applied, the gain settings do not influence
this signal. The iris video output is 0.7 V p-p from 75 
and without sync. This signal is always output except EPS
and PWC modes.

Fig. 5. Iris video output.

6.2. Trigger input

When TI=1, the trigger input is on pin #10 on
the 12-pin connector. The input is AC coupled.
To allow a long pulse width, the input circuit
is a flip-flop, which is toggled by the negative
or positive differentiated spikes caused by the
falling or rising trigger edges.
The trigger polarity can be changed by TP=1.
Trigger input level is 4 V 2 V. It can be
terminated by SW600 : ON for 75. OFF for
TTL. The trigger inputs can be changed to
Camera Link. (TI=0 for CL)

Fig. 6. Trigger input.

6.3. Digital output interface (Camera Link® interface)

The video output is Camera Link with 3 x 8 bits RGB video placed in a base configuration, or 3
x 10 bits or 3 x 12 bits RGB placed in a Camera Link medium configuration. The digital output
signals follow the Camera Link standardized multiplexed signal output interface. The Camera
Link output driver is NS type DS90CR285MTD.
The data bits from the digital video, FVAL, LVAL, DVAL and EEN are multiplexed into the
twisted pairs, which are a part of Camera Link. Trigger signals and the serial camera control
are fed directly through its own pairs. The trigger input can also be TTL on the 12-pin
connector.
For details of the Camera Link® standard, visit the AIA web site www.machinevisiononline.org.

6.3.1 Camera Link® bit allocation

The AT-030MCL outputs an RGB signal via Camera Link. A 3 x 8-bit signal is allocated via a
Base configuration through port 1, while a 3 x 10-bit or 3 x 12-bit signal is allocated via a
Medium configuration through both port 1 and port 2.

On the next page, there is bit allocation table.

7. Functions and Operations

7.1. Basic construction

A 32-bit microprocessor controls all functions in the AT-030MCL camera. The CCD sensor
output is normalized in CDS and preamplifiers. The signals are then digitized to 14 bits.
Digital gain control, color matrix, look-up tables and setup can do signal processing in 14 bits
before the signal is converted to a 12-, 10- or 8-bit Camera Link signal.

Fig. 9. Principle diagram for signal processing

7.2. Main functions

7.2.1 Partial scan (SC)

The partial scanning function uses the middle of the image vertically to achieve faster frame
rates. This is very useful when capturing and inspecting an image which does not require the
full height. The AT-030MCL has 4 types of pre-set partial scan modes: 2/3, 1/2, 1/4 and 1/8.

Fig.10 Partial scan (pre-set)

In addition to pre-set partial scan modes, the AT-030MCL has a variable partial scan mode.
The offset line can be set from the 1st line to 493th line and the height can also be set from
2 lines to 494 lines. In actual use, the offset line plus height must be within total lines.

 How to calculate total line number and frame rate in variable partial scan mode

Frame rate (fps) = Horizontal frequency(61571Hz) / Total lines

Total lines = Blanking period + Fast Dump period in the upper part of the frame (L) +

Effective image period (L) + Fast dump period in the lower part of frame (L)

Where,

Blanking period = 4L (Fixed)

Calculation example
Read out: 1/2 partial at the center , Height(246), Offset(123)

Blanking period =4L
Fast dump period for the upper part = (123 + 9) ÷6 +2=24
Effective image period = 246
Fast dump period for the lower part = (494-(123+246) + 2) ÷ 6 =21.1  22
Total lines = 4+24+246+22=296

Frame rate = 61571/296 =208.1 fps

7.2.2 Vertical Binning (VB)

Vertical Binning mode is a function where the signal charges from 2 adjacent (vertical) pixels
are added together and read out as one pixel. Binning results in half vertical resolution but
higher frame rate and sensitivity. The charge accumulated in 2 adjacent lines is added
together in the horizontal CCD register. This is done by providing two pulses to the vertical
CCD register for each line read out. Vertical binning cannot be used together with partial
scanning.

7.2.3 Electronic shutter (SM)

The AT-030MCL has the following shutter modes.

 Pre-set shutter(SM-0)

The setting command is from SH=0(OFF) to SH=10（1/130,000）
OFF(1/120),1/250,1/500,1/1000,1/2000,1/4000,1/8000,1/18,000,1/25,000,1/40,000 and
1/130,000s

Note: The actual exposure uses the programmable exposure (PE) method. When the camera receives a
pre-set shutter value, it is converted to a programmable value inside the camera. So, the actual
exposure might be slightly different from the pre-set value.

 Programmable Exposure (PE) (RGB Common and RGB Individual)

The setting command is PE and the exposure time can be controlled from 0L to 511L in 1
LVAL units (16.24µs). Calculating actual shutter speed requires adding 0.5L to the
setting value. This is because there is 0.5L overhead.
The resulting range is from 0.5LVAL to 511LVAL. Setting 511L is Shutter OFF.
The programmable exposure can be set for R, G and B together (SM=1) or individually (SM=2)
in EPS and RCT modes.

Note1: If V-Binning and partial scan modes are used, the maximum shutter speed is limited
by the programmable exposure value of total line numbers in one frame.
Note2: In Pulse Width mode, the minimum trigger pulse width requires more than 2LVAL.

 Auto exposure

AT-030MCL has an automatic shutter function which sets the video at an appropriate level
depending on illumination.

7.2.4 Auto-detect LVAL-sync / a-sync accumulation

This function replaces the manual setting found in older JAI cameras. Whether accumulation
is synchronous or asynchronous in relation to LVAL depends on the timing of the trigger input.
When a trigger is received while FVAL is high (during readout), the camera works in LVAL­synchronous mode, preventing reset feed-through in the video signal. There is a maximum
jitter of one LVAL period from issuing a trigger and accumulation start.
When a trigger is received during FVAL low, the camera works in LVAL-asynchronous mode (no
delay) mode.

This applies to both Edge Pre-select (EPS) trigger mode and Pulse Width Control (PWC) trigger
mode.

(1) In this period camera executes trigger at next LVAL (prevents feed-through noise)

(2) Avoid trigger at FVAL transition (+/- LVAL period), as the function may randomly

switch between “ next LVAL ” and “ immediate ”.

In this period, camera executes trigger immediately ( no delay).

7.2.5 Shading compensation (SDM)

The AT-030MCL implements a digital shading compensation
circuit for the white shading which could be caused in the
prism or optical system. The whole image is divided
horizontally and vertically and uses the center level as the
reference. The circuit will compensate the difference between
the center and each divided area. The range for compensation
is a maximum of 30%.

Shading correction mode: SDM
0:OFF, 1:Factory shading, 2:User 1, 3:User2
These are used to load the stored data.

In order to calibrate the shading, use RS command, Recalibrate Shading correction.
Param. 1 is used to store the calibration data in 0 for User 1 and 1 for User 2. User 1 and User
2 can store only one data set for either color shading or flat shading. Param. 2 can be set to
0 for Flat or 1 for Color and executes the shading correction and the storing of data.

Note: Conditions for lens used with AT-030MCL
In order to get an appropriate picture, it is recommended to use 1/3 inch or larger,

3CCD lenses. Shading is dependent on F value and focal length. Using a wide angle lens
or using the lens fully open, will cause the shading characteristics to deteriorate.

AT-030MCL has two shading compensation circuits.

1. Color shading compensation
In this mode, the shading is compensated using the G channel as the reference.
Adjust R and B channels to match the characteristics of the G channel. Use white balance

to match R, G and B levels.

Fig.15 Conceptual drawing for color shading compensation

2. Flat shading compensation
In this mode, each channel can be adjusted to achieve flat characteristics.
