Understanding the JPEG System

The StudioZ Producer JPEG Compression/Decompression system provides the capability to compress and decompress images. It is a single Peripheral Component Interface (PCI) board that accelerates the compression and decompression operations in a hardware engine.
The following figure represents the JPEG Compression/Decompression board.
Digital Video Connector
JPEG Compression/ Decompression Processor
The JPEG system provides direct memory access capability to allow compression and decompression to occur with minimal host CPU intervention. JPEG compression works on each image individually. Images (raster data blocks) in system memory can be compressed and then stored to system memory. Compressed images can also be decompressed with both the source and destination being system memory. Images must comprise an integer multiple of 8 x 8 pixel blocks.
Quality of a reconstructed image is a function of how much the image was compressed. The video quality factor (controlled by StudioZ Producer) and the contents of the compressed image determine the compression ratio. Compression ratio is the size (in bytes) of the original image divided by the compressed image. The higher the video quality factor, the higher the quality of the image and the lower the compression ratio. Higher video quality also requires larger disk space. The lower the video quality factor, the greater the compression ratio and the more likely an image contains visible artifacts of the compression process.
The compression algorithm used by the JPEG board has loss (not a bit-for-bit copy of the original), but the algorithm preserves information needed to reconstruct a copy that is visually faithful to the original.

Adjusting System Ergonomics

This section provides human-factors (ergonomic) recommendations you should follow when setting up and using the ImageStation Z system. Perform the following steps in the order presented.

Adjust the Cyborg Chair

Use the reference material provided with the Cyborg chair to make the following adjustments.
To adjust the chair:
1. Adjust the seat height so that your feet are flat on the floor and your knees are bent approximately 90 degrees.
17
NOTE If needed, use a footrest to allow feet to rest on a flat surface. Do not use the table as a footrest. CAUTION The digitizer table work surface is a non-load bearing surface. Damage to sensitive parts may occur if
used for purposes other than intended. Operator injury or mechanical damage could occur.
2. Adjust the seat to distribute the weight of the upper body comfortably over the seat. The seat should be nearly level.
3. Adjust the height and angle of the backrest to maintain contact with the lumbar area of the back when you are sitting in a normal working posture.
4. Adjust the height of the armrests to support the arms when your shoulders are relaxed and your upper arms are at your side.

Adjust the Digitizer Table

Adjust the height of the digitizer table so that your arms are comfortably at your side when using the two-handed controller or keyboard.
Your elbows should be bent at approximately 90 degrees when your hands are resting on the two­handed controller or at the keyboard. If the table is at the lowest setting, you may need to raise the chair height to place your hands at a proper height. A footrest may be required if your feet do not rest flat on the floor.
To adjust the digitizer table:
1. Move the digitizer table out from under the monitor table when using the entire digitizing area.
2. Lock the casters on the digitizer table when in use to prevent it from moving unintentionally.

Adjust the Monitor Table

The monitor table should be centered along the back edge of the digitizer table so that the monitor screen will be directly in front of you.
Adjust the height of the monitor table so that the center of the monitor screen is slightly below eye level.

Adjust the Monitor Position

The monitor should be placed on the monitor table. The monitor base should be centered on the table top to evenly distribute the weight of the monitor on the table. This position allows enough room for the placement of the keyboard in front of the monitor, if desired.
NOTE Avoid placing the monitor so that it reflects glare from room lights.

Adjust the Keyboard Position

The keyboard can be placed in any position on the digitizer table, or on the front of the monitor table, according to your preference.
To use the keyboard:
1. For periods of infrequent keyboard input, place the keyboard on the front edge of the monitor table in front of the monitor.
2. For periods of frequent keyboard input, place the keyboard on the digitizer table in front of you.
NOTE When not in use, the keyboard can be moved to either side of the digitizer table.

Adjust the Two-Handed Controller

The two-handed controller uses a standard bobbin, ten buttons, and two force-operated joysticks called force sticks. The ten buttons are application-specific. They are mapped and specified within the application software.
CAUTION Exerting excessive force on the buttons and force sticks can cause fatigue or may cause them to
break.
The thumb lever force sticks are sensitive to force rather than to displacement, and require minimal force to operate. Over-straining the force sticks will not speed performance.
The ten buttons require minimal force and should be pressed until a click is heard or felt. Excessive force will cause fatigue.
