About ALC and EEI operations

Specifications

ALC stands for Automatic Level Control and EEI for Extended Electronic Iris. ( page E34) By making the respective settings, the Automatic Level Control (ALC) will operate under dark lighting, and the electronic shutter (EEI) will operate under bright lighting. Furthermore, setting the IRIS mode to AUTO will synchronize sensitivity, iris and electronic shutter so that an appro- priate signal level can be acquired automatically at all times. The ALC mode increases sensitivity from 0dB to +12dB under dark lighting and the EEI modeautomatically adjusts the range of 1/7.5 s to 1/2384.7 s (calculated value) under bright lighting. In other words, the signal level is adjusted in the range of 2 graduations of the aperture under dark lighting and 8 graduations under bright lighting. When the IRIS mode is set to manual, the sensitivity and electronic shutter change continuously while the iris setting stays fixed. ( page E33 IRIS MODE) This feature holds the advantage of being able to shoot under changing light conditions without the depth of field altering.

MEMO

The status of ALC and EEI can be displayed on the screen. (  page E40 AE DISPLAY)

When EEI is used, the amount of change in one step of the signal level will be large and the precision becomes bad as the shutter speed is faster.

When analog output is used, and EEI LIMIT is set to 1s when a dark subject is shot, the image will appear intermittently so the 1/7.5s setting should be used.
