General Description

1.2 Introduction

Introduction

The MC-1000WU-20A is one of a series of high-resolution video cameras that
employs TI’s mega-pixel CCD image sensors. The cameras are intended for
scientific and industrial imaging applications where image data processing is
required.

The MC-1000WU-20A camera employs the TI TC215 full-frame CCD image
sensor, which features 1,017,000 active photosites, resulting in a very-high­resolution image. The TC215 sensor provides high sensitivity and good
spectral response as a result of the TI patented Virtual Phase technology.

The TC215 sensor measures 17.2 mm diagonally and features 12-mm square
pixels. The square pixels permit symmetrical image measurement in both the
X and Y axis. The photosite has a 100% fill factor and is responsive to wave­lengths in the ultraviolet through the visible and into the near-infrared spectral
regions. The camera outputs composite analog video at a 20-mega-pixel per
second data rate. Two operating options can be selected - a normal operating
mode and a programmable shutter mode. In addition, the camera provides for
auto-iris control.

A mechanical shutter or strobe light is recommended for most
MC-1000WU-20A camera applications. The shutter operation is synchronized
to the camera by supplying an external shutter command signal. The shutter
may operate from a minimum integration time of 1/2500 second to 1/125
second or 10 frames/s maximum. Figure 1–1 shows the camera interface
options and mode selection.

1.3 Physical Description

The MC-1000WU-20A camera is housed in an aluminum case 210.6 mm long
(excluding lens) by 68.0 mm high by 68.0 mm wide. It is self-contained except
for power supply and monitor. The camera weighs 2.09 pounds.

The MC-1000WU-20A offers a standard TV C-mount lens attachment with an
adjustable lens locking ring to allow precise adjustment of the lens back focal
length. A variety of lenses or mechanical shutters may be used.

(??Page 3–4 says three ??)Two standard 1/420 threaded tripod mounting
holes on the baseplate allow secure mounting.

Equipment Required But Not Supplied

1.5 Equipment Required But Not Supplied

The MC-1000WU-20A camera uses the full-frame TC215 CCD image sensor.
This full-frame format sensor requires a mechanical shutter or an electronic
light strobe to prevent image smear. The shutter or strobe light allows scene
information to be captured during either the open time of the shutter or on-time
of the strobe light. The transfer or read-out of the captured scene information
is performed during the closed time of the shutter or off-time of the strobe.
Once the shutter or strobe light is chosen, an appropriate lens may also be
selected.

The MC-1000WU-20A camera supplies analog video at either a 15-Hz frame
rate in the TV mode or a 10-Hz frame rate in the shutter mode and can be
displayed directly to a video monitor capable of those frame rates. However,
many applications require the addition of a custom or commercially available
frame-buffer or other video processing equipment. This hardware will enable
the user to capture and digitally process the scene information. The
MC-1000WU-20A is presently supported by several manufacturers of video
processing hardware and software systems. Most manufacturers have
application notes available describing the interface required.

Installation Procedure

3.2 Installation Procedure

The following paragraphs describe installation procedures for the
MC-1000WU-20A camera.

3.2.1 Mounting the Camera

The camera can be mounted using any one of (??T wo on page 1–4??) three
1/420-thread mounting holes located on the camera base plate.

3.2.2 Connecting an Auto-Iris Lens

Most auto-iris lenses can be used with MC-1000 series cameras. Connect the
auto-iris lens to the MC-1000WU-20A camera per the auto-iris connector pin­out table in Section 3.1 and the lens wiring schematic provided by the lens
manufacturer.

3.2.3 Connecting a Standard Lens

A number of standard C-mount or shutter attachments may be used with the
camera. The camera employs a lens locking ring to fix the minimum distance
between the rear lens element and the CCD imager.

3.2.4 Connecting the AC/DC Power Supply

The PS-1000 power supply is recommended for use with the camera, because
it already has the proper power connector installed. A bench supply can also
be used, provided that the bench supply output meets the power requirements
of the camera listed in Chapter 2.

3.2.5 Connecting the Monitor

Video may be viewed directly from the camera by attaching a video cable to
the video input jack of a TV monitor. The monitor must be capable of 15 Hz
vertical synchronization. The video may also be the input source to commer­cially available frame-buffer or other video processing hardware. The video
signal should be properly terminated into a 75-ohm load. A mechanical shutter
or strobe light will be required in most applications.

Installation

3.3 Post-Installation Test

When the power and monitor connections have been made, test the camera
by applying power to the monitor and the external power supply (if used). The
green power-on LED on the camera rear panel should light and an image
should appear on the display . It may be necessary to operate the shutter con­trol or frame-buffer hardware to obtain an image. In addition, the lens may re­quire focus adjustment to obtain a sharp picture.

General Operating Procedures

4.1 General Operating Procedures

The MC-1000WU-20A camera features high-resolution, stable, very sensitive,
linear images from an array of 1000(H) by 1017(V) picture elements. The cam­era operates as one unit of a user-defined imaging system. Other components
typically consist of a mechanical shutter or strobe light, a TV frame-buffer or
frame-storage computer or hardware system, an optical system (lens), and a
power supply . The MC-1000WU-20A camera operates with little or no opera­tor adjustment after the initial setup period. The following paragraphs give op­erating procedures for the camera.

4.1.1 Turn-On Procedure

The camera does not have a power switch; as soon as power is applied by the
power supply, the camera becomes operable. The green LED on the rear
panel signals that power is applied to the camera. After connection of the
power supply, a picture should appear on a monitor screen within a few
seconds. If additional frame-buffer hardware is used in the application, verify
that the hardware is working properly.

4.1.2 Turn-Off Procedure

T o turn off the camera, remove the power connector from the camera, or switch
off the appropriate system power supply.

4.1.3 Focusing

The MC-1000 series cameras use a lens-locking ring to set the minimum dis­tance between the rear lens element and the CCD imager. Focus the lens by
rotating the front lens barrel clockwise or counterclockwise until the image is
sharp. If a sharp image cannot be obtained, do the following steps:

1) Check lens surface for smears, smudges, or dust. Clean lens surface per
lens manufacturer’s instructions.

2) Check glass cover on CCD imager for smears, smudges, or dust. Clean
glass cover with alcohol and a cotton swab. See Chapter 6, Maintenance
Instructions, for details.

3) Check the distance between the rear lens element and the CCD imager.
If necessary, adjust the distance by loosening the lens-locking ring.
Remember to tighten the lens-locking ring after adjusting to fix the new
distance setting.

4.1.4 Adjusting Image Brightness

Image brightness is a function of exposure time (which is fixed in standard TV
applications) and lens aperture (F number). The sensitivity of the CCD sensor
and the amount of light reaching the sensor through the optical system is a
function of scene illumination, optical alignment, and magnification. In most
cases, the image brightness can be adjusted by varying the lens aperture. If
an image is too dark, rotate the lens aperture ring to a smaller number. This
selects a larger lens aperture, allowing more light through the lens.

CCD Circuit Description

The CCD Array

5.1 The CCD Array

The TC215 is a full-frame charge-coupled device (CCD) image sensor that
provides very-high-resolution image acquisition for image processing
applications such as robotics vision, medical x-ray analysis, and metrology.

The image format of the sensor measures 12.0 mm horizontally by 12.2 mm
vertically; the image area diagonal is 17.2 mm. The image area contains 1017
active lines with 1000 active pixels per line. Six additional dark reference lines
give a total of 1024 lines in the image area, and twenty-four additional dark
reference pixels per line give a total of 1024 pixels per horizontal line. The
pixels are 12 mm square and form precise rows and columns, horizontally and
vertically, allowing precise image geometry measurements.

The CCD is a solid-state device, which requires no external adjustment or
regular maintenance. Unlike a conventional pickup tube, there are no
electromagnetic alignment routines to be observed because there is no
electron beam involved.

The full-frame image sensor should be used with a shutter or with strobed
illumination to prevent smearing of the image during readout. After image
capture (integration time), the readout is accomplished by transferring the
charge one line at a time into two serial registers, each of which contains 512
data elements and 12 dummy elements. The typical pixel rate is
20 mega-pixels per second using both serial registers. Operating the TC215
at the typical data rate of one field per frame generates video at a continuous
15 frames per second in the TV mode of operation.
