1. PDC-2000 Description

General Description

The Polaroid

Digital Camera, Model PDC-2000 (Figure 1-1), captures high-quality color

pictures electronically. It has all the features of an automatic compact 35mm camera, including

automatic exposure, electronic flash and automatic focus. These features produce correct

exposure, accurate colors and sharp focus under a great variety of picture-taking conditions.

Manual overrides are also provided for unusual conditions.

With appropriate image-processing software (such as Polaroid PicturePro or Adobe

Photoshop) and the Polaroid PDC-2000 plug-in software on a Macintosh computer or PC,

users can view the pictures taken with the PDC-2000 camera and transfer them to their

computer via a standard SCSI-2 interface. They can then use image-processing software to

manipulate, enhance, save and print the pictures.

When the camera is connected to a computer, the camera can be controlled and operated via

the computer keyboard and mouse. This is useful when the camera is used in a stationary

setup.

Models

The PDC-2000 is available in three different models:

Model Internal Storage Capacity (Megabytes)

PDC-2000/40 40 (40 images)

PDC-2000/60 60 (60 images)

PDC-2000/T None; tethered operation only

Front

Rear

PDC 2000/3000 Repair Manual Description

7

Tethered operation refers to operation of the camera while it is connected to a computer. The

PDC-2000/T has no internal storage and must be connected to a computer to be operable.

Instead of storing images internally, it immediately transfers them to the computer as they are

captured.

Features

The PDC-2000 is designed for completely automatic, point-and-shoot operation. It

automatically sets exposure, focus and flash mode based on ambient light and distance to the

subject. Manual overrides are available for setting focus to infinity, setting flash mode to on or

off, and setting white balance to daylight, incandescent or fluorescent. A backlight-

compensation setting is also available.

The camera is capable of transferring its images to the computer in either of two resolutions:

(1) standard (800x600 dpi) and high (1600x1200 dpi). Both resolution modes are 24-bit color.

Because the camera always stores enough raw image data to produce the high resolution

images, resolution is not selected until pictures are being transferred to the computer.

Power for the camera is provided by four AA rechargeable NiCad batteries. These batteries

can be charged in the camera, using the battery charger provided with the camera. The

camera is operable while the batteries are charging.

An LCD panel on the camera provides information about time and date, camera status,

remaining battery capacity and error conditions. Time and date are recorded in the header of

each picture file, and on-camera controls allow the user to attach an additional alphanumeric

label to each picture file header. Time, date, label, and camera status transfer with the image

to the computer to aid identification and troubleshooting.

2. Theory of Operation

Picture Data Flow

Picture data flows through the PDC-2000 camera from the CCD sensor to the SCSI interface is

shown in Figure 2-1. This analog and digital data is processed through the following modules:

• CCD sensor

• Video signal processor

• Frame buffer

• Internal storage

• Median filter interpolator

• SCSI interface

Median Filter Interpolator

Standard Resolution Mode

The median filter interpolator converts RGB triplets received from the frame buffer to an 800 x 600

(standard resolution for the PDC-2000) RGB image by arranging the pixels and averaging

adjacent horizontal pixels as shown in Figure 2-2. It sends the reconstructed pixel data to the

SCSI interface.

High Resolution Mode

When the operator through the host computer decides to transfer a picture in the high-resolution

mode (1600 x 1200) instead of standard resolution, data from the frame buffer passes directly to

the SCSI interface without passing through the camera’s median filter interpolator (Figure 2-1).

In this high resolution mode, the host computer processes the frame buffer data to produce a

1600 x 1200 pixel image as shown in Figure 2-3.

3. PDC-2000 Testing and Adjustment

LabView

Overview

LabView is a graphical application program designed by National Instrument. It is used to

graphically program instrumentation systems for data acquisition and control, data analysis,

and data presentation. This application program offers an innovative method in which a

design engineer can graphically assemble software modules called virtual instruments (VI's)

instead of writing text-based programs. VI's can be used to acquire data from plug-in boards

and programmable instruments such as PDC 2000/3000 digital cameras. VI's can also be

assembled to analyze data and to present results through graphical user interfaces.

A LabView virtual instrument (VI) consists of:

• Front Panel

• Block Diagram

• Icon/Connector

The following paragraphs only gives an overview of the LabView components necessary to

design a test program. Refer to the LabView User's Guide for more detailed information

pertaining to the LabView components necessary to design a test program.

Front Panel

The front panel is the user interface. It serves as an interactive interface for supplying

inputs to and observing outputs from the instrumentation system. LabView makes

creating a front panel as simple as drawing a picture and gives the user a variety of

controls and indicators to use.

When the VI is completed, the user uses it to control his/her system - even while the VI is

running - by clicking a switch, moving a slide, tweaking a knob, or entering a value from

thekeyboard, the front panel responds immediately, providing real-time feedback from the

instrumentation system.

Once the necessary information is entered or selected from the applicable front panel, the

user then starts the VI by clicking on the Start button. It then performs the test and

displays its results in the Test Status window on the front panel. Refer to the applicable

Testing and Adjustment section for a detailed explanation of the PDC 2000/3000 front

panel.

16

PDC 2000/3000 Repair Manual Testing&Adjustment

Block Diagram

The block diagram is the source code of the VI. It is constructed, free from syntactical

details of conventional programming, by selecting functional blocks from LabView menus.

The selected functional blocks are then connected with lines called wires to pass data from

one block to the next. These blocks include arithmetic functions, advanced acquisition and

analysis VI's, Sub VI components which call other VI's, and network and file I/O functions

that store or retrieve data in ASCII, binary, or spreadsheet formats.

Icon/Connector

The icon/connector is the calling interface. The icon is the graphical ID of the VI, and the

connector assigns controls and indicators to VI input and output terminals.

Test Software

The Test Software is an application program that was developed using LabView software

(National Instrument) and Concept VI Image Processing Library (Graftek). It is intended to

help the repair person diagnose PDC 2000/3000 digital camera malfunctions. Programs

developed using LabView are called virtual instruments (VI's).

The developed software consists of a Tester which invokes the necessary sub-VI's routines

that allow the repair person to check the PDC 2000/3000 digital camera.

When the Tester is invoked, it performs and verifies specified camera tests.

At the completion of the specified test, a report file is generated by the Tester indicating

whether or not the tested functions passed ( Pass ) or failed ( Fail ). It also list the current

parameters for the test functions so that repair person can verify the tested functions with the

PDC 2000/3000 digital camera specifications.

If the report file indicates that all or a particular function failed ( Fail ), the repair person can

compare the current parameters with the PDC 2000/3000 digital camera specifications to

determine how to bring the failed function/functions back into specification.

17

PDC 2000/3000 Repair Manual Testing&Adjustment

Tester Operation

Starting the Tester

1. If applicable, click the mouse on the front panel white arrow to start the tester.

2. Click the mouse on the Start button to start the test sequence.

3. Tester prompts the user to perform specified function when testing the PDC 2000/3000

digital camera.

4. Once all user prompts are completed, the test sequence for the PDC 2000/3000 digital

camera begins.

5. Upon completion of all or partial tests, a test completed message appears in the Status box

of the test panel.

Also, a test report and the Pass / Fail indicators displayed on the test panel are updated.

Stopping the Tester

Note: The Tester should not be stopped in the middle of a test sequence. However, if an

emergency situation occurs, use the following steps to stop and restart the Tester.

1. Click the mouse on the stop box to completely stop the camera's test sequence.

The black arrow changes to a white arrow indicating that the run-time version of LabView

stopped running.

2. To restart the Tester, just click the mouse on the white arrow; the arrow becomes black

again and the tester resumes.

Quitting the Tester

To quit the Tester due to a malfunction or before the selected tests are completed, just

click the mouse on the Closing box.
