SAFETY CHECK-OUT

After correcting the original problem, perform the following
safety check before return the product to the customer.

1. Check the area of your repair for unsoldered or poorly
soldered connections. Check the entire board surface
for solder splasher and bridges.

2. Check the interboard wiring to ensure that no wires are
“pinched” or contact high-wattage resistors.

3. Look for unauthorized replacement parts,
particularly transistors, that were installed during a
previous repair. Point them out to the customer and
recommend their replacement.

4. Look for parts which, though functioning, show obvious
signs of deterioration. Point them out to the customer and
recommend their replacement.

5. Check the B + voltage to see it is at the values specified.

6. Make leakage - current measurements to determine
that exposed parts are acceptably insulated from the
supply circuit before returning the product to the customer.

7. CAUTION: FOR CONTINUED
PROTECTION AGAINST FIRE

SAME TYPE 2.5 AMPERES 125V

1.General

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.

FinePix A330 SERVICE MANUAL

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

The FinePix A303 incorporates a 1/2.7 -inch square pixel, primary color interline CCD of 3.34 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”, 3.34 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=

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 square pixel, primary color interline CCD of 3.34 million pixels[total]

[IC101]) 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 required

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 (1.5, 60,000 pixels) is used.

Chip Size Packege IC

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.
