5. Dark signal
Block all light falling on the imaging element surface and measure the CCD output signal from the center of the
image. At this time, do not take the difference between the signal level and the optical black segment level, but rather
take the difference with the no signal level that has no pixel information. See Figure 5.

Block Descriptions
No. 4971-7/9
LC9947G
OSC
Generates the basic frequency (28.636 MHz) for synchronization signals and timing pulses
Timing pulse generator IC
Generates the pulses required for the video signal (SYNC, blanking, etc.) and the pulses required for driving
the CCD. This IC includes a built-in CCD horizontal driver and provides an electronic iris function.
Driver IC
Amplifies the pulses described above to their prescribed levels and drives the CCD device.
Level shifting circuit
Drive pulse level shifter
Signal processing IC
Video signal processing, including sample and hold, clamping, AGC, gamma correction, white clipping, and
pedestal addition.
