Automatic Exposure Mode

The variety of AE functions, which allow video signal to output the optimum image for subjects from low light conditions to bright light conditions, are available.

•Full Auto

Auto Iris and Gain, Fixed Shutter Speed (59.94/ NTSC: 1/60 s, 50/PAL: 1/50 s)

•Slow shutter limit

Lower limit of the slow shutter mode in the Full Auto mode. For the 59.94/NTSC video format, select the lower limit from among 1/60, 1/30, 1/15, 1/8, 4/1 or 1/2.

For the 50/PAL video format, select the lower limit from among 1/50, 1/25, 1/12, 1/6, 1/3 or 1/2.

•Shutter Priority 1)

Variable Shutter Speed, Auto Iris and Gain

(1/2 to 1/10,000 s, 21 steps, high speed shutter: 15 steps,

slow shutter: 6 steps)

•Iris Priority

Variable Iris (F1.8 to Close, 18 steps), Auto Gain and Shutter speed.

•Manual

Variable Shutter, Iris and Gain.

•Bright

Variable Iris and Gain (Close to F1.8, 18 steps at 0 dB: F1.8, 6 steps from 0 to 18 dB)

•Spot light

Avoids a situation where the face of the subject is over-illuminated, and becomes whitish.

Basic Functions

AE – Shutter Priority

The shutter speed can be set freely by the user to a total of 21 steps – 15 high speeds and 6 low speeds. When the slow shutter is set, the speed can be 1/30, 1/15, 1/8, 1/4, or 1/2 s. The picture output is read at a normal rate from the memory. The memory is updated at a low rate from the CCD. AF capability is low.

In high speed mode, the shutter speed can be set up to 1/10,000 s. The iris and gain are set automatically, according to the brightness of the subject.
