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).
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 adjust-
ing 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.

FinePix A204 (EU/EG/GE/AS) SERVICE MANUAL 3.Schematic
3-3. Explanation of Main Block Functions
3-3-1. Technology Outline
The FinePix 2650/A204 incorporates two new ICs - a intelligent highly integrated image processor IC (WCS:304)
The intelligent highly integrated image processor IC (WCS:304) is equivalent to the image signal processing IC (VCS:
IC209) incorporated in previous models of the FinePix 2600Zoom, however it provides a dramatic reduction in imaging/
playback interval time, and improved S/N ratio and image sharpness.
Time required for transfer of software via the USB interface is reduced due to the use of the WCS internal buffer.
3-3-2. Explanation of Block Functions
(1) CCD signal processing/Imaging circuit (CCD block) (CAM block)
The analog video signal from the CCD (1/2.7, 2,000,000 pixels, square pixel CCD) is pseudo color compensated
(CDS), optimally interpolated (CDS), amplified (AGC), and signal is mixed (CDS) in the single-chip CSP_IC (IC103:
SCS3A), and converted (A/D) to a 12-bit digital signal (CSP_IC = Chip Size Package IC). The CSP_IC incorporates
the TG/SSG function previously supported with a separate IC into a single IC. The converted digital signal is sent to
the intelligent highly integrated image processor IC (WCS:304).
This block contains a horizontal/vertical drive IC (IC102) to drive the CCD.
(2) Motor Circuit (MOTOR block)
The signal processing system IC (WCS:304) receiving the commands from the various switches controls the AF
MOTOR DRV (IC703), SHUTTER DRV (IC703), ZOOM MOTOR DRV (IC703), and IRIS MOTOR DRV (IC703), and con-
trols each motor with the relevant driver.
(3) Image Signal Processing (PROCESS block)
(Input data from CCD)
The 12-bit digital image data (1H equivalent) from the imaging block (CCD_CAM block) is sent to the intelligent
highly integrated image processor IC (WCS:304), buffered in its internal buffer, and converted to 32-bit (128-bit) data
(CCD raw data). The 32-bit image data (CCD raw data) is saved in the 32 Mbyte SDRAM (IC305) via the image signal
processor IC I/O bus. A single frame (1600 pixels x 1200 lines) of image data is held temporarily in the SDRAM. The
32-bit image data in the intelligent highly integrated image processor IC (WCS:304) is processed in the AUTO math
processor, and sent to the SCS3A_IC (IC103) in the CAM block to obtain the optimum AE, AWB, and AF.
(Recording on xD-Picture Card)
The image data saved in the SDRAM (IC305) is sent to the signal processing block one line at a time via the intelligent
highly integrated image processor IC (WCS:304) I/O bus. It is then unpacked (ie. converted from 32-bit to 12-bit) in the
signal processing block, and pre-processed using digital clamping, g compensation, and conversion of R, G, and B
data to 12-bit to 8-bit. Each 8-bit digital R, G, and B signal is then subject to YC processing to produce a Y:Cb:Cr ratio of
4:2:2, and each 8-bit Y, Cb, and Cr image data is then sent again to the internal buffer. Each 8-bit Y, Cb, and Cr signal is
then sorted in the internal buffer to facilitate DCT compression, and recorded in the xD-Picture Card via the JPEG
processor and media controller.
(Image replay from xD-Picture Card)
Compressed image data from the xD-Picture Card is sent to the intelligent highly integrated image processor IC
(WCS:304) as eight bit image data, and finally sent to the SDRAM (IC305) via the media control unit, DMA unit, and
internal bus control unit. The image data temporarily stored in the SDRAM (IC305) is then returned to the intelligent
highly integrated image processor IC (WCS:304), and then sent to the image processing block via the media
controller and JPEG processor. Each 8-bit Y:Cb:Cr image signal is then converted to 8-bit R, G, and B signals,
simultaneously superimposed on text display signals, and sent to the LCD block.
The imaging adjustment data is stored in the WCS (IC304).
(4) Power supply (DCDC block)
The power supply circuit on the DC board is used to generate the 1.5V[WCS(IC304)], 3.4V[WCS(IC304), SDRAM
(IC305), RSW PWB, STRB], 3.4V[EVR(IC302/303)], CAM_3. 4V (CAM_BLOCK), LCD_3.4V(LCD), MOT_3.4V
(MOTOR_BLOCK), MOT_5.25V (MOTOR_BLOCK), -8.0V(CCD), 15.5V(CCD, LCD), and UNREG voltages.
