1.General
Fine Pix A120 SERVICE MANUAL
1-2.Explanation of Terms
Deactivated batteries: Leaving an Ni-MH battery unused in storage for a long period may cause a rise in
the level of substances that inhibit current flow inside the battery and result in a
dormant battery. A battery in this state is referred to as deactivated.
Because current flow is inhibited in a deactivated Ni-MH battery, the battery’s
original level of performance cannot be achieved.
DPOF: Digital Print Order Format
DPOF is a format used for recording information on a storage media (image
memory card, etc.) that allows you to specify which of the frames shot using a
digital camera are to be printed and how many prints are made of each image.
EV: A number that denotes Exposure Value. The EV is determined by the brightness
of the subject and sensitivity (speed) of the film or CCD. The number is larger for
bright subjects and smaller for dark subjects. As the brightness of the subject
changes, a digital camera maintains the amount of light hitting the CCD at a constant level by adjusting the aperture and shutter speed.
When the amount of light striking the CCD doubles, the EV increases by 1. Likewise, when the light is halved, the EV decreases by 1.
Frame rate (fps): The frame rate refers to the number of images (frames) that are photographed or
played back per second. For example, when 10 frames are continuously photographed in a 1-second interval, the frame rate is expressed as 10 fps.
For reference, TV images are displayed at 30 fps.
JPEG: Joint Photographics Experts Group
A file format used for compressing and saving color images. The higher the compression rate, the greater the loss of quality in the decompressed (restored) image.
Memory effect: If an Ni-MH battery is repeatedly charged without first being fully discharged, its
performance may drop below its original level. This is referred to as the “memory
effect”.
Motion JPEG: A type of AVI (Audio Video Interleave) file format that handles images and sound
as a single file. Images in the file are recorded in JPEG format. Motion JPEG can
be played back by QuickTime 3.0 or later.
PC Card: A generic term for cards that meet the PC Card Standard.
PC Card Standard: A standard for PC cards determined by the PCMCIA.
PCMCIA: Personal Computer Memory Card International Association (US).
White Balance: Whatever the kind of the light, the human eye adapts to it so that a white object
still looks white. On the other hand, devices such as digital cameras see a white
subject as white by first adjusting the color balance to suit the color of the ambient
light around the subject. This adjustment is called matching the white balance.
Exif Print: Exif Print Format is a newly revised digital camera file format that contains a vari-
ety of shooting information for optimal printing.

3-3.Functions of Primary Blocks
3-3-1.Technical Outline
1/2.7 -inch CCD of 3.1 million pixels(total).
An [xD picture card] is adopted as the recording media. ICs are the [AFE (IC171)] for CCD processing, [HPS IC
(IC301)] that incorporates power supply management capabilities into operation system processing, and system LSI
[XCS2 (IC202)] that pakeged signal processing, LCD drive, V-TG functions.
Video-out (NTSC/PAL) is added.
3-3-2.MAIN Board Block Functions
Photography Circuit Functions (MAIN BLOCK)
The analog video signal output from the CCD (1/2.7”, 3.1 million effective pixels,) is processed (pseudo-color
compensation, adaptive interpolation, amplification, and signal mixing) in AFE_IC (ENGINE PWB: IC171:CSP_IC),
and subsequently converted to a 12-bit digital signal. The digital signal is then sent to the single chip image signal
processing LSI : XCS2_IC (IC202 : CSP_IC*).
* CSP_IC=Chip Size Packege IC
3-3-3.ENGINE Board Block Functions
Image Signal Processing Functions (ENGINE BLOCK)
Data input from CCD
* The analog signals output by the CCD (1/2.7 CCD of 3.1 million pixels[total] [IC1]) undergo color compensation,
adaptive interpolation, amplification (ACG) and signal mixing in the [AFE(IC171)] CCD signal processing IC. After
that, the signals are converted into 12-bit digital signals and sent to the [XCS2_IC (IC202)] system LSI. This block
has a vertical drive IC (IC172) for driving the CCD.
* At the same time, AE multiplies the 12-bit image data input from the XCS2_IC in [AUTO], and sends the data re-
quired for AE/AWB/AF to the SDRAM_area. To provide the appropriate data for AE/AWB/AF, this data is then sent
from the SDRAM_area in serial format to the AFE_IC via the XCS2_IC.
Recording in the xD media
The image data stored in the SDRAM_area is converted from 16-bit to 12-bit data one line at a time in the [IBUF] in the
XCS2_IC, and sent to [YC PRO]. The image data is then converted to 8-bit Y and C signals in [YC PRO], and then sent
again to [IBFC]. The 8-bit Y and C signals are then converted to 8-bit Y, Y, Cb, and Cr signals and sent to the
SDRAM_area. The image data stored in the SDRAM_area is compressed with [JPEG] in the XCS2_IC and again
stored in the SDRAM_area. The image data following compression is recorded sequentially in the xD media in the
XCS2_IC.
Image Replay from the xD media
The compressed image data from the xD media is sent to XCS2_IC, and stored in the SDRAM_area via [MEDIA].
The compressed image data stored in the SDRAM_area is expanded with JPEG and stored again in the
SDRAM_area. The expanded image data is sent to [YC PRO] via [IBFC]. Gain control for the luminance and color
difference signals, and aperture processing, are performed in [YC PRO] and the image data then sent again to the
SDRAM_area. The image data is then displayed via [ENCD] and [D/A].
The photography adjustment data is stored in the FLASH_ROM (In the IC204). The FLASH_ROM also incorporates
firmware.
LCD Control Functions
The R, G, and B signals processed in the image signal processing XCS2_IC are output to the LCD panel via [LCD CONT].
A low-temperature polysilicon TFT color LCD monitor (62,000 pixels) is used.
Power Supply Functions
The power supply on the ENGINE board and MAIN board generates the -7.5V/15V (CCD), 1.5V (XCS2_IC), 3.3V
(AFE_IC/XCS2_IC/F_ROM/LED/KEY), MOT_5.0V (lens/flash), D_5V (AUDIO), LCD_13V (LCD backlight), D_3.3V
(LCD), and AD_3.3V (Video/ LCD) voltages.
