TECHNICAL DESCRIPTION
15
4-3-3 Card Still Picture Recording
<CCD> IC1054 / CCD PCB
• 1/3.9-inch interlaced CCD
• RGB primary color filter
• Total number of pixels : Approx. 2,200,000
Effective number of pixels : Approx. 1,230,000 for tape recording
: Approx. 2,000,000 for card recording
<CDS/AD> IC1000 / MAIN PCB
Extracts signals read through 2 left and right channels from CCD, eliminates noise components, performs A/D conversion, and then
outputs digital signal through 2 channels.
<MPX2> IC1002
Composes picture data input through 2 left and right channels, and corrects the offsets. Then performs AGC processing, corrects
CCD missing pixels, and outputs the signal through 1 channel.
<DIGIC DV> IC1102
Performs different camera signal processing (EIS, AWB, etc.) and digital effect processing. Also performs signal processing for
coping with multimedia centered on still picture shooting.
• Feature engine
• High-speed card interface
• JPEG method compression/extension
• Audio data compression (ADPCM)
• USB function
