Basic Functions AE - Shutter Priority The shutter speed can be set freely by the user to a total of 22 steps - 16 high speeds and 6 low speeds. When the slow shutter is set, the speed can be 1/30, 1/15, 1/8, or 1/4 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.

AE - Bright The bright control function adjusts both the gain and iris using an internal algorithm according to a brightness level freely set by the user. Exposure is controlled by gain when dark and by iris when bright. As both gain and iris are fixed, this mode is used when exposing at a fixed camera sensitivity. When switching from Full Auto or Shutter Priority Mode to Bright Mode, the current status will be retained for a short period of time. Only when the AE mode is set to "Full Auto" or "Shutter Priority," the user can switch it to "Bright."
