ELURA20 MC A, ELURA10 A
CAHPTER 2. TECHNICAL DESCRIPTION
2-12
4-2 Major Functions of Each Microcomputer
(1) MAIN MI-COM (IC100)
The MAIN MI-COM, as the nucleus of the system, carries out control of mode transition plus mechanism control through commu-
nication with CAMERA MI-COM. It also detects the input of various sensors and switches (DMCII). Following are the major
functions.
• VIC2 (Video IC) control/VIF2 (Video Interface) control/AIF (Audio Interface) control
• Control in accordance with IEEE1394
• Key input
• LANC communication
• LCD control
• OSD (On Screen Display) control
• DMCII mechanism control
(2) SUB MI-COM (IC203)
The SUB MI-COM is mainly in charge of the power-on sequence and charging control. Following are the major functions.
• Key input
• Remote control input
• Power ON/OFF control
• MIC (Memory In Cassette) control
(3) CAMERA MI-COM (IC1401)
Carries out lens control and camera signal processing. Following are the major functions.
• CCD drive control
• AE, AF, AWB control
• EIS (Electric Image Stabilizer) control
• Zoom key input
4-3 Servo Control
Servo control is made by the MAIN MI-COM. and VIC2 the same as heretofore. The MAIN MI-COM. controls motor ON/OFF,
turning direction, etc. and VIC2 controls the speed of revolution, phase and outputs the signal. The signal flow is such that VIC2 detects
the FG/PG, PB-RF, etc. from motor and send them to the MAIN MI-COM. The MAIN MI-COM generates the error signal and outputs
it to the VIC2 again. The VIC2 outputs the error signal (PWM), and the MAIN P.C.B. drives that signal and sends it to the motor driver
IC as a control voltage.
