Frame count for outside the dead band
This function is used to ensure that the AE operation will not overly respond to changes in the subject when an object
has passed cut across the shooting screen while AE is in the appropriate status. Tracking is started when the AE error
amount is above the setting and this has continued for at least the number of Frame count for outside the dead band
frames.
The dead band range is the setting × 16 × 6.02/1024 [dB].

Gain Priority Mode
Gain Priority(0x28) involves adjusting the shutter time automatically so that image is set to the optimum brightness
after the gain level is fixed. Set the AE mode register to normal AE =0[h] or long AE =1[h]. When the value except =
0[h] is set on the Gain Priority(0x28) register, the mode is gain priority. When it is 0[h], the mode is removed.
Shutter Priority Mode
Shutter Priority (0x29-0x2A) functions to automatically adjust the gain with the shutter time fixed to achieve the
appropriate images. Set the AE mode register to normal AE =0[h] or long AE =1[h]. When =0[h] is set, shutter priority
is set to off, and the normal AE mode is established.
