Operation

TM-75/76 High-Resolution CCD Camera

3.2 Operating Modes

Besides normal operation, the TM-75/76 supports the following versatile operations that can be

selected:

• Standard Interlace Mode

Field integration Mode

Frame Integration Mode

• External Sync Mode

• Interlace Scan Mode

• Non-interlace Scan Mode

• Reset-Restart Mode with Electronic Shutter

Trigger Width Mode

Trigger Position Mode

Snapshot Mode (Donpisha Mode)

3.2.1 Standard Interlace Mode

See Section 5, “Operation Mode,” for setting and operation of modes.

3.2.1 (a) Field Mode and Frame Mode

The ﬁeld and frame integration mode is selectable. The frame integration is used to separate all CCD

pixels and the exposure of Odd and Even ﬁelds generate the full frame image shown in the ﬁgure below.

3.2.1 (b) Field Mode Binning

The ﬁeld integration is done by combining two pixel rows (binning) together, each pair alternating as

interlace scan is generated. Row 1 is binned with row 2, and row 3 is binned with row 4. In Field 2, row

2 is binned with row 3, row 4 with row 5, and so on.

3.2.2 Cyclic (Continuous) Shutter Mode

With rotary switch shutter control, the TM-75/76 operates at the internally predeﬁned shutter speeds.

Each ﬁeld output is exposed for the same period. The shutter control varies the substrate discharge

timing. The duration between the shutter pulse and transfer gate timing (9.5H from VD leading edge for

EIA, 14.5H for CCIR) decides the exposure time. The following four cyclic shutter modes are available:

• High-Speed Cyclic Shutter mode

• Trigger Position Reset/Restart Shutter mode

• Trigger Width Reset/Restart Shutter mode

• Snapshot Reset/Restart Shutter mode

Contact PULNiX for timing charts of various cyclic shutter modes.
