Operation

TMC-6700/1000 Series Progressive Scan CCD Digital Color Camera

FIGURE 10. External Pulse Width Control

3.5.2 (b) Long Integration

With pulse-width control, long integration is possible up to a few seconds besides integration control

(pin #11 of the 12-pin connector).

3.5.2 (c) Internal Fast Reset Mode (1H~8H, or 1/16,000~1/2,000)

When fast reset mode is selected, the camera resets with internal VINIT timing which is latched to H

Video output is also synchronized with internal VINIT timing without further delay. The shutter speed

is controlled by the shutter dial.

3.5.2 (d) Internal Slow Reset Mode (9H~1048H, or >1/2,000~1/15)

With the Internal Slow Reset mode selected, the camera operates the reset and shutter by the same

means as the wide pulse width control mode. When external VINIT pulse is applied, internal VINIT is

latched to H

D and the second internal VINIT signal is generated to set up the shutter speed period.

Video output timing starts right after the second internal VINIT.
