SAFETY CHECK-OUT

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

FinePix F401 Service Manual

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. Caution: For continued protection against

1-2. Explanation of Terms

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 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.

JPEG: Joint Photographics Experts Group

A file format used for compressing and saving color images. The compression ratio can be selected, but the higher the compression ratio, the poorer the quality of the expanded 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).

FinePix F401 Service Manual

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. A function that automatically matches the white balance is called an Automatic White Balance function.

3. Schematics

3-3. Functions of Primary Blocks

3-3-1. Technical Outline

The FinePix F401 incorporates the new generation [Super CCD Honeycomb III], and two new ICs - the [Intelligent

Highly Integrated Image Processor IC (VCS2; IC302)], and the [Power Supply Management IC (PWR_ON_IC; IC252)]. The [Intelligent Highly Integrated Image Processor IC (VCS2; IC302)] is the equivalent of the [Image Signal Processing IC (MD2305; IC204; CSP)] in the previous FinePix 2500Z. The new IC allows a major reduction in photography

and playback interval time, and also contributes to better S/N ratio and sharpness, and thus to improvements in image quality. Software-controlled USB communications, and the use of a VCS internal buffer, provides for a reduction in data transmission time.

3-3-2. Block Functions

(1) CCD signal processing/photography circuit (CCD BLOCK) (CAM BLOCK)

 The analog video signal output from the CCD (1/2.7", 2,100,000-pixel super CCD Honeycomb III) is subject to

pseudo-color compensation processing (CDS), adaptive interpolation processing (CDS), amplified (AGS), and signal mixing (CDS) in the single chip CSP_IC (IC103; SCS3A)*, and is then A/D converted to a 12-bit digital signal. The CSP_IC incorporates the [TG and SSG functions] previously supported by discrete ICs. The converted digital signal is sent to the Intelligent Highly Integrated Image Processor IC (VCS2; IC302). (* CSP_IC - Chip Size Package IC)

 This block incorporates an OFD control IC (IC 101) and a horizontal/vertical drive IC (IC102) for CCD drive.

(2) Motor circuit (MOTOR BLOCK)

 The signal processing system IC (VCS2; IC302) receives commands from the switches, manages the motor drive

IC (IC 203), and controls the AF, SHUTTER, ZOOM, and IRIS motors.

(3) Image signal processing (PROCESS BLOCK)

 (Input data from CCD)

The 12-bit digital image data (equivalent to 1H) output from the CCD_CAM BLOCK is sent to the Intelligent Highly Integrated Image Processor IC (VCS2; IC302), buffered in the [internal buffer], and converted to 32-bit (16-bitx2) data (CCD RAW data). The converted 32-bit image data (CCD RAW data) is sent to two 16Mbyte SDRAMs (IC303, IC304) via the [I/O bus] in the image signal processing IC for temporary storage (a single frame equivalent (1600 pixels x 1200 lines) of image data is temporarily stored in the SDRAMs).

It is calculated in the [AUTO COMPUTE BLOCK] using the 32-bit image data input to the Intelligent Highly Inte- grated Image Processor IC (VCS2; IC302) and sent to the SCS3A_IC (IC103) in the CAM BLOCK to obtain the optimum AE, AWB, and AF.

 (Recording in the SSFDC)

Image data stored in the SDRAMs (IC303, IC304) is sent one line at a time to the [PROCESS BLOCK] via the [I/O bus] in the Intelligent Highly Integrated Image Processor IC (VCS2; IC302). This data is unpacked (converted from 32-bit to 12-bit data) in the [PROCESS BLOCK], preprocessed (digitally clamped, ƒÁ compensated, each of R, G, and B 12-bit data converted to 8-bit data), each of the digital R, G, and B 8-bit signals YC processed (Y:Cb:Cr ratio adjusted to 4:2:2), and each of the Y, Cr, and Cb 8-bit image data sent to the [internal buffer] again. In the internal buffer, each of the Y, Cr, and Cb 8-bit signals are sorted into a format readily subject to DCT compression, sent via the [JPEG COMPUTE BLOCK] and [media controller] and recorded in the SSFDC.

 (Image data playback from the SSFDC)

Compressed image data from the SSFDC is sent as 8-bit image data to the Intelligent Highly Integrated Image Processor IC (VCS2; IC302), and then sent to the SDRAMs (IC303, IC304) via the [media control unit], [DMA unit], and [internal bus control unit]. The image data temporarily stored in the IC(IC303,IC304) is returned to the Intelli- gent Highly Integrated Image Processor IC (VCS2; IC302), and sent to the [PROCESS BLOCK] via the [media controller] and [JPEG COMPUTE BLOCK]. Each of the Y, Cr, and Cb 8-bit image data signals are post-processed (converted to 8-bit R, G, and B signals) in the [PROCESS BLOCK], text display signals superimposed, and sent to the LCD BLOCK.

 Photography adjustment data is stored in the FLASH ROM (IC305).

(4) LCD control (LCD BLOCK)

The R, G, and B digital signals input to the [LCD BLOCK] IC (IC452) from the Intelligent Highly Integrated Image Processor IC (VCS2; IC302) are sent directly to the LCD drive IC for LCD drive and LCD panel brightness control.

(5) Power supply (DCDC BLOCK)

The power supply circuit on the DC board supplies 1.5V [VCS (IC302)], 3.3V [VCS (IC302), FLASH_ROM (IC305), SDRAM (IC304/IC305), KEY PWB, MRSW PWB SSFDC, POWER_ON_IC (IC252), STRB], CAM_3.3V (CAM_BLOCK), MOT_3.3V (MOTOR_BLOCK), MOT_5.2V (MOTOR_BLOCK, BL_BLOCK, AUDIO_BLOCK), -8V (CCD), -8.5V (LCD), 12V (BL_BLOCK), 16V (CCD, LCD), and UNREG.
