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.

FinePix F455 Service Manual

1. General

1-2. Explanation of Terms

AF/AE Lock: On the FinePix F455, pressing the shutter button down half way locks the focus and

exposure settings (AF and AE lock). If you want to focus on a subject that is not centered in the frame or change the picture composition after the exposure is set, you can obtain good results by changing the composition after the AF and AE settings are locked.

Auto power save function: If the camera is not used in any way for 60 seconds, this function turns features such as

the LCD monitor off (sleep mode) to prevent battery depletion and the waste of power when the AC power adapter is connected. If the camera is then left unused for a further period, the Auto power save function turns the camera off. This period can be set to 2 or 5 minutes on this camera.

• The Auto power off function does not operate in PC mode, during automatic playback, or if it is disabled during setup.

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 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 1second interval, the frame rate is expressed as 10 fps. For reference, TV images are displayed at 30 fps (NTSC).

JPEG: Joint Photographic 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.

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). Smear: A phenomenon specific to CCDs whereby white streaks appear on the image when there

is a very strong light source, such as the sun or reflected sunlight, in the photography

screen. WAVE: A standard format used on Windows systems for saving audio data. WAVE files have

the “.WAV” file extension and the data can be saved in either compressed or

uncompressed format. Uncompressed recording is used on this camera.

WAVE files can be played back on a personal computer using the following software:

Windows: MediaPlayer

Macintosh:QuickTime Player

* QuickTime 3.0 or later

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 variety of

shooting information for optimal printing.

3-3. Functions of Primary Blocks

3-3-1. Technical Outline

 Equipped with a 1/2.5-inch square-pixel interline CCD (with 5.2 effective megapixels) and a 3.4x optical zoom lens

featuring the new slimline sliding lens system.

 Features a new image signal processing LSI chip, called the XCS2_IC (IC204, CSP_IC), built into the MAIN PWB ASSY.

This CPU incorporates the standard peripheral I/O functions as well as the peripheral functions required for still image processing into a single chip. Standard peripheral I/O consists of the interrupt controller, DMA controller, clock controller, SDRAM controller, block selection controller, serial I/O, multifunction timer, monitoring timer, programmable I/O ports, USB 2.0 (Full Speed), microprocessor ADC, microprocessor DAC, image processing circuit, JPEG compression/ expansion circuit, display control circuit, still image processing and card interface circuit.

 In the white balance procedure, an algorithm has been installed that provides an estimation of the light source used for

shooting based on the brightness and light source color detected when the shot was taken, and a white balance (WB) compensation function based on that estimation. The new algorithm is designed to prevent “hunting” due to field-of-view slippage by providing more accurate brightness and color detection, and to allow the installation of a powerful algorithm for distinguishing between the light source and the original subject colors.

 Flash brightness is adjusted using the CCD-TTL method in which the flash brightness is calculated from the CCD

feedback data generated by the pre-flash.

3-3-2. MAIN Board Block Functions

Explanation of the imaging circuit functions

 Analog video signals output from the CCD (1/2.5-inch with 5.2 effective megapixels) undergo pseudo-color correction

processing, adaptive interpolation processing, amplification and signal mixing in the AFE_IC (IC151; CSP_IC). The converted digital signals are then sent to the single-chip image signal processing LSI chip, known as XCS2_IC (IC204,

CSP_IC).  Input data from the CCD * The 10-bit digital image data (corresponding to 1H) sent from the imaging circuit (AFE BLOCK) is sent to XCS2_IC,

buffered in the chip’s IBFC and replaced by 16-bit (96 MHz) data. The replaced 16-bit (96 MHz) image data is then stored

in the XCS2_IC [SDRAM] via the XCS2_IC [I/O BUFFER]. The image data for each frame is temporarily stored in the

XCS2_IC [SDRAM]. * At the same time, the AE for [AUTO] is calculated using the 10-bit image data input to XCS2_IC and the data required for

AE, AWB and AF is sent to the XCS2_IC [SDRAM]. In the XCS2_IC [SDRAM], the data is sent serially to AFE_CS to

obtain the correct AE, AWB and AF.  Recording onto an xD-Picture card

The image data stored in SDRAM is converted to 16-bit (96-MHz) data by [IBFC] in XCS2_IC one line at a time and then

sent to [YC PRO]. In [IBFC], the 32-bit Y and C signals are each converted to 8-bit Y, Y, Cb and Cr signals and sent to the

XCS2_IC [SDRAM]. The image data stored in the XCS2_IC [SDRAM] is compressed using [JPEG] in XCS2_IC and then

recorded sequentially onto the xD-Picture card via [MEDIA] in XCS2_IC.  Playing back images from an xD-Picture card

The compressed image data from the xD-Picture card is sent to XCS2_IC and stored in the XCS2_IC [SDRAM] via

[MEDIA]. The compressed image data stored in the XCS2_IC [SDRAM] is expanded using [JPEG] and again stored in

the XCS2_IC [SDRAM]. The expanded image data is sent to [YC PRO] via [IBFC]. In [YC PRO], gain control and

aperture processing is applied for the brightness signals and color difference signals, after which the data is again stored

in the XCS2_IC [SDRAM]. The image data is then displayed via [ENCD] and [D/A].  In movie shooting mode

The 10-bit digital image data output from the imaging unit is converted to 8-bit Y and C signals by the XCS2_IC [YC PRO]

and sent to the XCS2_IC [SDRAM]. The image data is compressed using [JPEG] in XCS2_IC and again stored in the

XCS2_IC [SDRAM]. The compressed data is then recorded sequentially onto the xD-Picture card via [MEDIA] in

XCS2_IC.  The imaging system adjustment data is stored in FLASH_ROM (IC202).

Explanation of the LCD controller functions

 The R, G and B signals processed in the XCS2_IC image signal processor are output to the LCD panel via [LCD

CONST].

3-3-3. LCD CONST Block Functions

 The LCD monitor (2.0-inch 1.54 megapixels) used in the camera uses a low-temperature polysilicon TFT color LCD

screen.

3-3-4. DCTS Board Block Functions

 The power supply circuits on the DCST board generate power supplies such as -8V/12V (CCD), UNREG (flash and LCD

backlight), 5.2V (lens), XCS_3.3V (XCS2_IC), CAM3.3V (AFE), D3.3V (LCD and F_ROM) and AD_3.3V (AUDIO/VIDEO).
