Fig. 5
The CCD is driven by the 1-chip engine (XFCR-MVP), and the output
video signal from the CCD is input into the XFCR-MVP through the
amplifying circuit and clamp circuit.
The ADC and buffer are provided in the XFCR-MVP, and the digital
image processing is performed.
(6) Speaker amplifier
The speaker amplifier monitors the line under the on-hook mode,
outputs the buzzer sound generated from the XFCR-MVP, ringer
sound, DTMF generated from the modem, and line sound.
