V
SHD/SHP external input: <SHD/SHP>
Brightness signal output for iris detection: <IRISOUT>
V
AGC gain variable range: 6 to 19dB (typ.)
The gain is controlled by the 8-bit DAC for DC voltage generation.
Manual setting possible by the register
10 bits
V
The input block clamp circuit pulse is generated internally, and external input is impossible.
Built-in voltage follower for the reference voltage
DGC (digital gain control) operates at the maximum AGC (analog gain control) gain.
The gain can be controlled from 0 to approximately 8 times.
The aperture signal coring level is automatically controlled in conjunction with the gain.
Right/left inverted output possible <MIRROR>
Horizontal and vertical aperture correction circuit
The circuit can be turned on and off by the setting pin. <APCON>
Fine adjustment possible by the register
The position at which the aperture correction signal is added can be switched to before or after gamma.
4 patterns can be selected by the setting pins. <GAMMA1, GAMMA2>
7-line approximation
Adjustable by the register
Sampling frequency selectable from 2MCKI or (2MCKI/2)
Standard setting: 7.5 IRE
Adjustable by the register
A 1-bit signal from an external pin can be added to the luminance signal. <CHARA>
The gain can be set by the register.
Up to a total of 10 white point blemishes can be detected and compensated during dark signal.
Blemish addresses can be read out by serial communication.
