(d) Power on reset
During electronic iris mode (IRENB = high), the initial settings for the iris are made in the instant the
POWER pin (Pin 54) switches from low to high.
The initial setting shutter speed is 1/1000 (s).
By applying the circuit shown below, the shutter speed can be initialized when the power is turned on.

(e) Backlight compensation
By applying the window pulse to the electronic iris detection signal (IRIS) input to IRIN (Pin 20) and the
AGC detection signal (DET OUT) input to AGCI1 (Pin 26), backlight compensation can be performed.
Compensation is achieved by detecting a limited area with the built-in analog switch for the window and the
external sample-and-hold capacitor. In addition, four types of backlight compensation areas can be
selected by combining the WSEL1 pin (Pin 59) and WSEL2 pin (Pin 60) as shown in the table below.
The basic circuit to perform the window operations is shown in the figure below, and window pulse timing
charts are shown on the following pages.

AGC Flickerless
By setting the FL pin (Pin 57) of the CXD2409R high when using the CXA1310Q AGC, the fluorescent light
flicker component generated by differences between the fluorescent light emission cycle and the EIA field
